Matrix Multiplication In C

Question

I\'m trying to solve a matrix multiplication problem with C. Matrix sizes given in problem (2x2) I wrote this code but it doesn\'t print result as I expect. I think I\'m missing

Answer 1

The problem is that in the line

matC[i][j] += matA[i][k] * matB[k][j];

you are adding things to matC, but when you create it, you don't initialize it, so it has garbage.

You sould do something like:

int matC[2][2] = {0} which will initialize all the matrix with 0's
