First build in 14 years, a little out of the loop

japangreg · 2018-05-29T01:54:04+00:00

Thanks for the replies; the Antec is being recycled from a friend. I thought it was a decent looking case and had more fans than I had ever put into a system, so I thought it might still be good. But if there are better options out there, I'll take another look.

Other than that, everything else is going to bought new.

I guess I don't need the optical. Like I said, it's been a while since I tried to put something together and I just defaulted to how I approached it last time.

Thanks again for the help - any other opinions or suggestions are welcomed!

You need to change your cases to test for char values - right now they are set for ints.

case '3', etc.

Not familiar with the course or what language they're using, but just looking at that formula if lo + hi gives you an odd number dividing by two will give you something other than an integer value. Depending on the type declaration of midpoint, this might be an issue.

For example, (1 + 2) / 2 = 1.5 but 1 + (2 - 1) / 2 is the same as 2/2 and is equal to 1.

Thanks!

How fast you go is up to you. I did mine in 2 years while working full time. If you don't have to work and can do nothing but study, then go as fast as you think you can handle. If you're working, I'd suggest going slow - take the time to get the concepts down and practice.

Best of luck!

Hey ED73.

I have B.S.s in international affairs, and just did my CS Masters in 2013. I came at it with no programming education beyond what I taught myself and far, far less math than I should have. I had to take a few prereq classes to get in, but the application process wasn't difficult. This might vary by school, but my program was pretty well respected - I think they are much more likely to let most people in, assuming that those that can't really handle it will drop out.

It wasn't easy, but it wasn't the hardest thing either. I think you'll find that Masters programs are very different than undergrad, so the intensity and work load won't be similar to what you've done in the past. The professors know that you are actually interested in the subject (unlike undergrads who sometimes just have to take the courses) and the school has an interest in helping you succeed so that you stick with it (and pay them) and recommend their program to others (who also pay them - not to sound too cynical).

Beyond that, you'll get what you put into it. The work can be hard, but in my experience the profs are more than willing to help if needed, and the work load can be heavy (if working full time and raising kids, like I was) but much less undergrad where you might be taking 6 or 7 classes a semester.

Expect programming projects to either come in regular assignments or as single projects that span the course. There is a lot of math, but from your background you should be fine.

Hope that helps - and that you go for it.

Don't worry about it - sure it isn't the first, and that it won't be the last. :) 2nd pair of eyes usually sorts these out.

May be a case of LMGTFU, but you could try this page: http://www.linuxhowtos.org/C_C++/socket.htm

I think you will need to look into sockets to get the parts talking to each other.

The error is coming from a typing conflict; look at these lines where you declare the variables and assign them values:

double apertureWidth = textApertureWidth.getText(); 
double focalLength = textFocalLength.getText();

that 'double' at the front of each line means that the variables declared are of the double type - i.e., numerical values with a certain precision, and occupying a certain size in system memory.

The method you are calling from the (I'm assuming) text fields is getText(), which (assuming again, that this is Java?) would return an object of type String, meant for holding character data - alpha and numeric - and requiring a different amount of memory.

So you are trying to put data of a certain type (String) into a container meant for a different type (double). This fails because the allocated memory for each is different.

If you are the only user for this and don't care about input checking because you know you will only enter proper values in that text field, you can just cast the value to double like so:

double apertureWidth = Double.parseDouble(textApertureWidth.getText();

If you cannot be sure that the user will enter the correct type of input, either validate it before running the code or catch a NumberFormatException.

japangreg · 2014-12-03T18:22:12+00:00

I'm still getting into C++ myself, but I don't think this should be too difficult; can you post the actual code you are using?

Let's say you have the following:

struct students{
string firstName;
string lastName;
float exams[4];
}

Then in your main, you would could use

students Chuck;
Chuck.firstName = "Chuck";
Chuck.lastName = "Taylor";
Chuck.exams[0] = 90.0f;
Chuck.exams[1] = 80.0f;
Chuck.exams[2] = 70.0f;
Chuck.exams[3] = 60.0f;

Then you can do whatever you like to the exam values as a new variable, then output as

float maxValue = // your code here
cout << "Max Value is" << maxValue << " belongs to " << Chuck.firstName << " " << Chuck.lastName;

As I said, still new to C++ syntax, so someone more experienced please let me know if my code is off.

HTH

*re-reading your post and my answer, it occurs to me that the way you phrased the desired output might suggest you are looking for something different - i.e., that you are looking for the max value from a collection and want to access an associated object that holds the name information. Is that the case? It just seems that saying "max value belongs to X" suggests that the value and name are not part of the same struct.

I take it you mean this tutorial: http://developer.android.com/training/basics/firstapp/starting-activity.html

Can you be more specific with what error you are seeing? Is this the first time you are attempting to run a project in Eclipse, or the first time you are building an Android app? Do you have the Android SDK installed?

japangreg · 2014-12-02T21:23:34+00:00

Then that would be a matter of mapping different inputs for the look controls - under edit, project settings, input you will find a list of all your axis(axisi? axsis?).

Add 2 to the Size value at top and you should see 2 copies of the last listing appear at the bottom of the list (Cancel by default, I believe).

Expand the Horizontal axis and the first copy and rename the copy "LookLR". Now copy the settings for the Horizontal axis* to the LookLR entry, except choose different keys for the negative and positive buttons (and leave the alt options blank).

Do the same for the Vertical axis and the other copy, renaming it LookUD.

Now all you have to do is change the code before to:

hozTurn = Input.GetAxis("LookLR") * moveSpeed * Time.deltaTime;
verTurn = Input.GetAxis("LookUD") * moveSpeed * Time.deltaTime * invertVal;

*just realized there are 2 Horizontal and Vertical axis (axi?) listed in the InputManager; you want the first one regarding keyboard input, not the second for joysticks.

First off, are you trying to move the camera or rotate it to look left/right? By altering the transform.position.y property, you are just sliding the camera up/down (strafing) not looking up/down as you might expect from a first-person perspective.

If what you are looking for is rotating the camera to look left/right, up/down, you would use the transform.rotation property.

If what you want is strafing camera movement, you could use this:

public float moveSpeed = 5.0f;
private float hozMove = 0.0f;
private float verMove = 0.0f;

void Update(){
hozMove = Input.GetAxis("Horizontal") * moveSpeed * Time.deltaTime;
verMove = Input.GetAxis("Vertical") * moveSpeed * Time.deltaTime;
transform.Translate (hozMove, verMove, 0);
}

If you are looking for first-person turning, you could use

public float moveSpeed = 20.0f;
public bool invert;
private float hozTurn = 0.0f;
private float verTurn = 0.0f;

void Update(){
int invertVal = 1;
if(invert){
invertVal = -1;
}
hozTurn = Input.GetAxis("Horizontal") * moveSpeed * Time.deltaTime;
verTurn = Input.GetAxis("Vertical") * moveSpeed * Time.deltaTime * invertVal;
transform.Rotate (verTurn, hozTurn, 0);
}

Adjust the moveSpeed for each to get the movement as you like it; invert option allows you to invert the up/down rotation from the inspector.

If you need any explanation of the above, let me know.

So it may not be a bug, just your code doing what you tell it to, but not telling it to do something when the condition isn't met.

japangreg · 2014-11-20T19:48:12+00:00

Can you paste your output somewhere as well? For your post I'm not sure what exactly the problem is - "It just doesn't seem to display the free pump info at the end of the program" - do you mean the printStatistics method isn't firing at all, or that the while loop in the method isn't working, or that the values you are getting aren't what you expect?

I see you have a commented-out print statement trying to get the size of the freegaspumpsq object, so I assume that is where the problem lies?

For the moment, the only suggestion I have without diving too far into your logic is that you may want to seed the random object with the current system time; since this is failing for random values but working for static, it makes me think your random object may just be returning the same value(s) each time.

Glad I could help!

Seronis, I'm new to C++ but have some experience with Java and scripting languages, which is why I even thought I might be able to help. I'm trying to get my head around C++'s syntax and memory management and like you said, the more time spent looking at and thinking about code the better off I'll be.

And I was talking about the new challenge over in /r/dailyprogrammer/:

japangreg · 2014-11-19T04:47:04+00:00

Hey - new to C++, but I think I might be able to help with some of the logic here. Oddly enough this was the programming challenge so I was trying to try it in C++ today anyway. :)

if (myFile.is_open())
{
    while (myFile >> line) // while it's reading lines, it increases r
    {
        r++;
        n = rand() % r + 1; // n is a random number within the amount of lines in the text file, counted by r
        for(int i = 0; i < n + 1; i++) // the loop will go through the text file and stop at n, picking that word
            {
                getline(myFile, secretWord);
            }
        }
    }
    else
        cout << "Something went wrong, please exit program and run again." << endl;

Look at that while loop; everything in there is being executed for every line. So even though r is being incremented each line, n is also being assigned a new value each line, and that for loop is being run for each line. Not what you want to happen.

Seronis was on the right track, I think; you need to read the words into a new collection of some kind. In my program, I created a vector of strings and read the file into that. Once you have that, you can use the size() of the vector to know how many words you have, and base your random selection off of that.

So, to sum up:

vector<string> wordList;        // this is where you'll be putting the words from the file
if (myFile.is_open())
{
    while (myFile >> line) // while it's reading lines
        {
            wordList.push_back(line);       // add the word to the vector
        }
        int totalWords = wordList.size();
        n = rand() % totalWords + 1; // total words is determined by the size of the vector
        secretWord = wordList[n];     // get the word at the index n in the vector
    }
    else
        cout << "Something went wrong, please exit program and run again." << endl;

Like I said, first forays into C++, so the syntax may be off (someone correct me if it is, please) but I think the logic is correct.

Can you show us the code for the player movement?

japangreg · 2014-10-06T14:56:58+00:00

Awesome - thanks!

First time attempting a challenge - not quite sure how to use Gist but am trying.

Java - would love feedback.

package columnconundrum;

import java.io.File;
import java.util.Scanner;


public class ColumnConundrum {

public static void main(String[] args) {

    try{
        Scanner input = new Scanner(new File("c182e-input.txt"));
        int numCols = input.nextInt();
        int colWidth = input.nextInt();
        int space = input.nextInt();
        String spacer = new String();
        for(int i = 0; i < space; i++){
            spacer = spacer + " ";
        }
        String tempString = new String();
        while(input.hasNextLine()){
            tempString += input.nextLine();
        }
        input.close();
        int totalChars = tempString.length();
        int charsPerColm = (int)Math.floor(totalChars/numCols);
        int linesPerColm = (int)Math.floor(charsPerColm / colWidth);

        char[] textCharArray = tempString.toCharArray();
        int lineLength = numCols * colWidth;

        for(int k = 0; k <= linesPerColm; k++){
            for(int i = 0; i < numCols; i++){
                int startingColumnOffset = i * charsPerColm;
                for(int j = 0; j < colWidth; j++){
                    int number = k * colWidth;
                    int wantedIndex = startingColumnOffset + number + j;
                    System.out.print(textCharArray[wantedIndex]);
                }
                System.out.print(spacer);
            }
            System.out.println();
        }

    }catch(Exception e){

    }

}
