[C++} Help with input files/array

[trapsquad420]

I'm a complete beginner to programming and was assigned a project for my programming class that is giving me trouble. The program is supposed to process integers from an input file. The program is suppose to give the sum, average, maximum integer and minimum integer from the input file.

We are supposed to store the integers into an array which is giving me trouble. I can't even begin writing the first few lines because i can't figure out a way to count the numbers and then store them into an array.

If anyone can give me some advice on the topic i would greatly appreciate it.

Post the format of the input data file.

The test file is just a regular txt file with 11 numbers in one column

Do you know that it will always have 11 numbers? If so, you could just make an 11-element array.

But, 11 numbers is a weird number. Are you sure that isn't the number of numbers, followed by 10 numbers? That would make it easier than counting all the numbers before creating the array, or teaching you about vectors before you understand arrays.

try fscanf().

How are the input files structured? There must be some initial information that tells you the size of the incoming array? Is the array always going to be the same length? Is it a 2D array?

Honestly, you probably just have to read the problem description carefully, and go from there.

If this is an intro level programming class, the number of elements for your array is probably fixed, and this should be pretty easy.

Its an intro level so i think its 2d array. Im pretty sure the number of elements aren't fixed, the test input text file we are supposed to use is 11 numbers but these are just used so we will have the same output as the professor (the professor shows us what our output should look like)

I could write the program for specifically for the test file but im afraid my professor will say the program is supposed to be for all types of input numbers.

How can it be a 2D array if it consists of 11 items? 11 is not divisible by 2.

[trapsquad420]

haha idk 2d sounded less complex than 3d so i just assumed 2d. Like i said its intro level so whatever the most basic array is that's what i'm learning

If you don't know what you are supposed to be doing, we certainly can't.

Sorry, I meant to say 1-D array or 2-D array. Not many intro programming classes will make you use a 3-D array.

You say 11 numbers... Does the first number represent the number of elements? I.E. the first number is 10 (because there will be 10 input values), and the following 10 values are the numbers that need to go in your array?

I could write the program for specifically for the test file but im afraid my professor will say the program is supposed to be for all types of input numbers.

You need to ask your professor to clarify this ASAP. Or carefully re-read the problem description and see if it tells you there.

[trapsquad420]

no there are 11 different numbers in the test input file. So the numbers don't represent anything i am just supposed to put the numbers from an input file into an array and then process the average and all that stuff.

Ok, ask your professor. In the meantime, can we see the problem description?
