The program accepts the order and elements of two matrices as input from the user. It then multiplies the matrices and stores the product in a third matrix. The product matrix is then printed to the screen. The program checks that the matrices can be multiplied by verifying that the number of columns of the first matrix matches the number of rows of the second.

Write a program in `C’ language that accepts two matrices as input and prints
their product.
#include <stdio.h>
#include <conio.h>
void main()
{
int a[10][10],b[10][10],c[10][10],i,j,k,m,n,p,q;
clrscr();
printf("Enter the order of the first matrixn");
scanf("%d%d",&m,&n);
printf("Enter the order of the second matrixn");
scanf("%d%d",&p,&q);
if(n!=p)
printf("The matrix can not be multipliedn");
else
{
printf("Enter the elements of the first matrixn");
for(i=0;i<m;i++)
for(j=0;j<n;j++)
scanf("%d",&a[i][j]);
printf("Enter the elements of the second matrixn");
for(i=0;i<p;i++)
for(j=0;j<q;j++)
scanf("%d",&b[i][j]);
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("The resultant matrix of multiplication:n");
for(i=0;i<m;i++)
{
for(j=0;j<q;j++)
printf("%dt",c[i][j]);
printf("n");
}
}
getch();
