2d array of unknown size ??
but I give them *A[N][M] it mean that columns and rows is defined :

#define N 100
#define M 100

And same for C is defined

C= (int**)malloc(n * sizeof(int*));
for (i = 0; i < n; i++){
C[i] = (int*)malloc(m * sizeof(int));
}

n : number of columns that's user give
m : number of rows that's user give

Does this is really necessary to free the memory like you did ??
Or you did this just to increase readability ??

Because program is going to end and close anyway. And allocated memory will be disallocated automatically.
