Write a program to multiply two matrices.

Aim:-Write a program to multiply two matrices. (Using formatted I/O).

Source Code:-

#include <stdio.h>

 int main()

{

 int m, n, p, q, c, d, k, sum = 0;

  int first[10][10], second[10][10], multiply[10][10];

  printf("Enter number of rows and columns of first matrix\n");

  scanf("%d%d", &m, &n);

  printf("Enter elements of first matrix\n");

  for (c = 0; c < m; c++)

    for (d = 0; d < n; d++)

      scanf("%d", &first[c][d]);

  printf("Enter number of rows and columns of second matrix\n");

  scanf("%d%d", &p, &q);

  if (n != p)

    printf("The matrices can't be multiplied with each other.\n");

  else

  {

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

 for (c = 0; c < p; c++)

      for (d = 0; d < q; d++)

        scanf("%d", &second[c][d]);

 for (c = 0; c < m; c++)

 {

      for (d = 0; d < q; d++)

 {

        for (k = 0; k < p; k++) 

{

          sum = sum + first[c][k]*second[k][d];

        }

       multiply[c][d] = sum;

        sum = 0;

      }

    }

 printf("Product of the matrices:\n");

  for (c = 0; c < m; c++)

 {

      for (d = 0; d < q; d++)

        printf("%d\t", multiply[c][d]);

     printf("\n");

    }

  }

 return 0;

}

Output
