Multiplication of two Matrices solution using c language--programming_info problem 6

Multiplication of two Matrices

This above example is just a reference picture. don't

think it as an input of an array.

you can give your own input.

#include<stdio.h>
int main()
{

    int a[5][5], b[5][5], c[5][5], m, n, p, q, i, j, k;

    printf( "Enter rows and columns of first matrix: ");
    scanf("%d%d",&m,&n);

    printf("Enter rows and columns of second matrix: ");
    scanf("%d%d",&p ,&q);

    if (n == p)
    {
        printf("\nEnter first matrix:\n");
           for(i = 0; i < m; ++i)
          {for (j = 0; j < n; ++j)
                scanf("%d",&a[i][j]);
                }

        printf("\nEnter second matrix:\n");
        for (i = 0; i < p; ++i)
            for (j = 0; j < q; ++j)
                scanf("%d",&b[i][j]);

        printf("\nThe new matrix is:\n");

        for (i = 0; i < m; ++i)
        {
            for (j = 0; j < q; ++j)
            {
                c[i][j] = 0;
                for (k = 0; k < n; ++k)
                    c[i][j] = c[i][j] + (a[i][k] * b[k][j]);
                printf("%d\t",c[i][j]);
            }
            printf( "\n");
        }
    }
    else
        printf("\n Matrix can't be multiplied");

    return 0;
}
