Write a C program to perform the following operation on matrices D = A + (B * C), where A, B and C are matrices of (3 X 3) size and D is the resultant matrix.

Ans.

#include<stdio.h>

#include<conio.h>

Void main()

{

int a[3][3],b[3][3],c[3][3],d[3][3];

int i,j,k;

for(i=0;i<=5;i++)

{

for(j=0;j<=5;j++)

{

for(k=0;k<=5;k++)

{

e[i][j]=e[i][j]+b[i][k]*c[k][j];

}

}

}

for(i=0;i<=5;i++)

{

for(j=0;j<=5;j++)

{

D[i][j]=a[i][j]+e[i][j];

}

}

for(i=0;i<=5;i++)

{

for(j=0;j<=5;j++)

{

printf(“%d \t”,d[i][j]);

}

printf(“\n”);

}
