Write a program to implement Multiplication of two matrices.

#include<stdio.h>    
#include<stdlib.h>  
int main(){  
int a[10][10],b[10][10],mul[10][10],r,c,i,j,k;    
system("cls");  
printf("enter the number of row: ");    
scanf("%d",&r);    
printf("enter the number of column: ");    
scanf("%d",&c);    
printf("enter the first matrix element: \n");    
for(i=0;i<r;i++)    
{    
for(j=0;j<c;j++)    
{    
scanf("%d",&a[i][j]);    
}    
}    
printf("enter the second matrix element: \n");    
for(i=0;i<r;i++)    
{    
for(j=0;j<c;j++)    
{    
scanf("%d",&b[i][j]);    
}    
}    
printf("multiply of the matrix: \n");    
for(i=0;i<r;i++)    
{    
for(j=0;j<c;j++)    
{    
mul[i][j]=0;    
for(k=0;k<c;k++)    
{    
mul[i][j]+=a[i][k]*b[k][j];    
}    
}    
}       
for(i=0;i<r;i++)    
{    
for(j=0;j<c;j++)    
{    
printf("%d\t",mul[i][j]);    
}    
printf("\n");    
}    
return 0;  
}

Output

enter the number of row: 3
enter the number of column: 3
enter the first matrix element: 
12 13 14
15 16 17
18 19 20
enter the second matrix element: 
21 22 23
24 25 26
27 28 29
multiply of the matrix: 
942     981     1020
1158    1206    1254
1374    1431    1488
