Hey everyone,
Im new on C and just now making my 'baby steps' here.
I will try to be clear,
I have two arrays that contains size of pairs of shoes (1 left,1 right).
First of all i goes on the two of them and finally put the quantity in a third matrix
[size][2].
I have a logical problem, I cant figure out how to put the index in the matrix.
The two arrays (left and right) are equal so i run on them together.
I hope I was clear.
Please be patient :)

What I have tried:

int left[], int s1, int right[], int s2, int sizes[SIZE][2]
	
for (int i = 0; i < left && i < right; i++) {

		if (left[i] != 0)
			s1 = left[i];
		sizes[i][1] = s1;

		if (right[i] != 0)
			s2 = left[i];
		sizes[i][2] = s2;

	}

Why are you capturing two left feet, rather than one of each?

First off, that is C, not C# - get your tags right, because although that look very similar they are very, very different languages and a solution for C# will not work at all in C, and a C solution would be abysmal C# code!

But you do need to remember that C arrays are zero based: and array with two elements will have indexes 0 and 1, not 1 and 2. So these lines are wrong:

C

sizes[i][1] = s1;

C

sizes[i][2] = s2;

But that seems like a very messy solution to a simple problem: have you considered using a struct instead?
