To find multiplication of two matrices

Question

#include <stdio.h>
#include<stdlib.h>
int main()
{
int m, n, c, d,k, first[10][10], second[10][10], mul[10][10];

printf("Enter the number of rows and columns of matrix\n");
scanf("%d%d", &m, &n);
printf("Enter the elements of first matrix\n");

for (c = 0; c < m; c++)
for (d = 0; d < n; d++)
scanf("%d", &first[c][d]);

printf("Enter the elements of second matrix\n");

for (c = 0; c < m; c++)
for (d = 0 ; d < n; d++)
scanf("%d", &second[c][d]);

printf("multiply of entered matrices:-\n");

for (c = 0; c < m; c++)
{
for (d = 0 ; d < n; d++)
{
mul[c][d] =0;
for(k=0;k<n;k++)
{
mul[c][d]+=first[c][k]*second[k][d];

}
}
}//for printing result
for(c=0;c<m;c++)
{
for(d=0;d<n;d++)
{
printf("%d\t",mul[c][d]);
}
printf("\n");
}

return 0;
}

Answer 1

Enter the number of rows and columns of matrix
3 3
Enter the elements of first matrix
1 2 3
4 5 6
2 3 4
Enter the elements of second matrix
2 3 4
2 3 6
2 3 5
multiply of entered matrices:-
12 18 31
30 45 76
18 27 46
