C program to find the product of two matrices



#include<stdio.h>
main()
{
int i,j,k,r1,c1,r2,c2,a[10][10],b[10][10],c[10][10];
printf("Enter the no. of rows and columns of matrix 1 : ");
scanf("%d%d",&r1,&c1);
printf("Enter the no. of rows and columns of matrix 2 : ");
scanf("%d%d",&r2,&c2);
if(c1==r2)
{
printf("Enter the matrix 1\n");
for(i=0;i<r1;i++)
{
for(j=0;j<c1;j++)
{
scanf("%d",&a[i][j]);
}
}
printf("Enter the matrix 2\n");
for(i=0;i<r2;i++)
{
for(j=0;j<c2;j++)
{
scanf("%d",&b[i][j]);
}
}
for(i=0;i<r1;i++)
{
for(j=0;j<c2;j++)
{
c[i][j]=0;
for(k=0;k<r1;k++)
{
c[i][j]=c[i][j]+a[i][k]*b[k][j];
}
}
}
printf("Product of matrices\n");
for(i=0;i<r1;i++)
{
for(j=0;j<c2;j++)
{
printf("%d\t",c[i][j]);
}
printf("\n");
}
}
else
printf("Matrix multiplication not possible");
printf("\n");
}
