Thread: add element of matrix-Urgent

Please , I need some help to add the elements of a matrix.

my program must read several matrices from a file and add all element for each matrix.

This is how I did it

Code:

for(i=0;i<size;i++)
{
for(j=0;j<size;j++)
sum=sum+A[i][j];
}

I initialized sum BEFORE the while loop (which is set to read all matricces unitil the end of file).
size is the size of the matrix.

I get wrong results.
can someone tell me what I am doing wrong?

thank you

After you've read the matrices in, print them out to make sure they look good.
