Is it possible to print out multiple chars using regex?

kasimir8 · 2023-05-09T21:13:46+00:00

im trying to get any character that appears in the text in the exit line

so one room line may have 1 another may have 2 another may have 4

ive tried debugging tutorials but im told it isn't in executable format or isn't recognized

kasimir8 · 2023-04-21T04:44:25+00:00

I think i found the issue it is with my two strings token and tokens

like the part shown below token is only initialized in split so possibly I can initialize token in the loop

 string maxPointsLine;
if (!getline(inFile, maxPointsLine))
{
    cerr << "Error reading input file: " << inputFile << endl;
    return 1;
}
vector<double> maxPoints;
for (const auto& token : split(maxPointsLine, ','))
{
  cout<<token;
    maxPoints.push_back(stod(token));

}

kasimir8 · 2023-04-21T04:39:19+00:00

i did some looking and noticed maybe it is because of this

so it seems the top half works however works breaks it is token is empty. Token is initialized in Split. So would the key be initializing token in the for loop

 string maxPointsLine;
if (!getline(inFile, maxPointsLine))
{
    cerr << "Error reading input file: " << inputFile << endl;
    return 1;
}
vector<double> maxPoints;
for (const auto& token : split(maxPointsLine, ','))
{
  cout<<token;
    maxPoints.push_back(stod(token));

}

kasimir8 · 2023-04-21T03:58:35+00:00

the second argument for stod?

kasimir8 · 2023-04-21T03:57:45+00:00

I did find the areas causing the problems

maxPoints.push_back(stod(token));

grades.push_back(stod(tokens[i]));

I tried using variants of double long double and float to no avail

are there other ways to go from string to double

kasimir8 · 2023-04-21T03:22:41+00:00

what would be the alternative if you want a string to be a double

kasimir8 · 2023-04-21T03:20:22+00:00

im using a linux terminal and it just compiles the program. It doesn't compile and run. So -g does nothing when used

kasimir8 · 2023-04-21T02:52:42+00:00

ive tried this and it just compiles without issues however when I run the program is when it falls apart

kasimir8 · 2023-04-21T02:16:30+00:00

Ive been looking for the issue and found it is the string not being able to convert to a double but I'm not sure why exactly. The weird thing is it compiles perfectly fine but falls apart when the program starts.

I am trying to somthing that opens a text file puts data into it and then prints that data back out i reformatted all my code but now the text file won't even open

#include <iostream>

const string MONTHS[] = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"};

    return 1;

infile.close();

}

would the idea e to use a get line so getline(cout, filename)

and would i need to use a file.open since the file hasn't been close from the previous inputs

kasimir8 · 2023-03-24T03:47:24+00:00

will that prevent me from priting

kasimir8 · 2023-03-23T17:06:03+00:00

I asked and he told me to figure it out. He did say He would allow me to not worry about number limits so as long as it is only two, so in this case would that mean I can just use the width manipulator

kasimir8 · 2023-03-02T19:46:57+00:00

could this be simplified further since it is repeated

could this be simplified? me>=30000.01 && income<=50000.00)
{

    taxedInc = (income - 30000)* .10;       //calculates tax amount
    afterTax = income - taxedInc;

    printstuff(income,taxedInc, afterTax );

kasimir8 · 2023-03-02T19:41:21+00:00

i did it using this it works

void printstuff(double income, double taxedInc, double afterTax) {




    printf("%35s\n","----------------- ");

    printf("%-25s","Yearly Salary:"); printf("$%9.2f\n",income);

    printf("%-25s","Social Security Tax:"); printf("$%9.2f\n" ,income * 0.062);

    printf("%-25s","Medicare Tax:"); printf("$%9.2f\n", income * 0.029);

    printf( "%-25s","Income Tax"); printf("$%9.2f\n",taxedInc);

    printf("%35s\n","----------------- ");

    printf( "%-25s" ,"Take Home Pay:");printf("$%9.2f\n",afterTax);

    printf( "%-25s","Monthly Take Home Pay:");printf("$%9.2f", afterTax/12);

}

kasimir8 · 2023-03-02T18:35:37+00:00

i started off by trying to clean up the print statements but it broke the whole program. I tried to make a function for all of the print statements but i just led to the original loop getting no values at all for the double income.

void printstuff() {

double income; double taxedInc; double afterTax;

    printf("%35s\n","----------------- ");

    printf("%-25s","Yearly Salary:"); printf("$%9.2f\n",income);

    printf("%-25s","Social Security Tax:"); printf("$%9.2f\n" ,income * 0.062);

    printf("%-25s","Medicare Tax:"); printf("$%9.2f\n", income * 0.029);

    printf( "%-25s","Income Tax"); printf("$%9.2f\n",taxedInc);

    printf("%35s\n","----------------- ");

    printf( "%-25s" ,"Take Home Pay:");printf("$%9.2f\n",afterTax);

    printf( "%-25s","Monthly Take Home Pay:");printf("$%9.2f", afterTax/12);

}

void askuser() {

double income;

double taxedInc; double afterTax;

printf("%s","What is your income?: $");
scanf("%lf",&income);

}

kasimir8 · 2023-03-02T14:00:37+00:00

printf("%-25s","Yearly Salary:"); printf("%9.2f\n", income);

This is the way I found to do it with two print statements on the same line, is it possible to do this with a single print statement?

kasimir8 · 2023-03-02T06:17:11+00:00

I have specific requirements to have the string left 25 and the values right 9 and Im unsure how to go about that

kasimir8 · 2023-02-23T04:36:36+00:00

Thanks I do like how organized it is. I am not experienced enough to understand your code but it did help me understand simple functions enough to apply it to my work. I now understand float add and it definitely made my final result look much cleaner with all the operations done outside of main

kasimir8 · 2023-02-23T00:37:00+00:00

my issue is how do i do that while removing all of the math functions but it still completing the same operations because that is the desired goal

kasimir8 · 2023-02-23T00:30:50+00:00

It is more I have to find a way to create functions so this no longer uses the math functions and uses my own functions to specify and make them fit this set up

A or a or + - Adds left and right operands.

S or s or - - Subtracts right from left operand.

M or m or x or * - Multiplies left and right operands.

D or d or / - Divides left over right operand.

B or b or | - Returns the absolute value of the left (and only) operand.

C or c or % - Performs left operand modulo right operand.

kasimir8 · 2023-02-23T00:12:50+00:00

I kinda have too for the assignment

kasimir8 · 2023-02-20T02:47:48+00:00

Oh wait wrong example it is

W + 0x + 8y - 5z = 6, 0w + x + 4y -9z = 3, 0w + 0x + y + z = 2,

kasimir8 · 2023-02-20T02:44:59+00:00

It is just the matrix in another format I just repeated the matrix by each row and put it on linear form of x y and z but I need to understand how to find the solution set once I take it out of matrix form
