C Program to Print Product of Two Matrices
Following C Program to Print Product of Two Matrices, then display the result on the screen:
The simplest form of multidimensional array is the two-dimensional array. A two-dimensional array is, a list of one-dimensional arrays. To declare a two-dimensional integer array of size [x][y], you would write something as follows
type arrayName [ x ][ y ];
Where type can be any valid C data type and array Name will be a valid C identifier. A two-dimensional array can be considered as a table which will have x number of rows and y number of columns.
The below A 3 x 4 Table show as per below.
Save program in a file, Compile program, debug errors, Execute or Run program with necessary inputs. Verify the outputs obtained.

Example : C Program to Print Product of Two Matrices
/* Program to print product of two matrices*/
#include <stdio.h>
int main()
{
int m, n, p, q, i, j, k, sum = 0;
int first[10][10], second[10][10], multiply[10][10];
printf("Enter the number of rows and columns of first matrix\n");
scanf("%d%d", &m, &n);
printf("Enter the number of rows and columns of second matrix\n");
scanf("%d%d", &p, &q);
if (n != p)
printf("Matrices with entered orders can't be multiplied with each other.\n");
else
{ printf("Enter the elements of first matrix\n");
for (i = 0; i < m; i++)
for (j = 0; j < n; j++)
scanf("%d", &first[i][j]);
printf("Enter the elements of second matrix\n");
for (i = 0; i < p; i++)
for (j = 0; j < q; j++)
scanf("%d", &second[i][j]);
for (i = 0; i < m; i++) {
for (j = 0; j < q; j++) {
multiply[i][j]=0;
for (k = 0; k < p; k++) {
multiply[i][j] = multiply[i][j] + first[i][k]*second[k][j];
}
}
}
printf("Product of entered matrices:-\n");
for (i = 0; i < m; i++) {
for (j = 0; j < q; j++)
printf("%d\t", multiply[i][j]);
printf("\n");
}
}
return 0;
}Output
Enter the number of rows and columns of first matrix 3 3 Enter the number of rows and columns of second matrix 3 3 Enter the elements of first matrix 1 2 4 5 2 1 4 5 2 the elements of second matrix 1 2 4 5 2 1 4 5 2 Product of entered matrices 10 18 28 50 18 7 40 45 14
