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 - IGNOU MCA Assignment 2018 – 19

Program:

#include<stdio.h>
void main()
{
int A[3][3],B[3][3],C[3][3],D[3][3],I,J,K;
clrscr();
printf(“ENTER 3X3 MATRIX A VALUES\n”);
for(I=0;I<3;I++)
{
for(J=0;J<3;J++)
{
scanf(“%d”,&A[I][J]);
}
}
printf(“ENTER 3X3 MATRIX B VALUES\n”);
for(I=0;I<3;I++)
{
for(J=0;J<3;J++)
{
scanf(“%d”,&B[I][J]);
}
}
printf(“ENTER 3X3 MATRIX C VALUES\n”);
for(I=0;I<3;I++)
{
for(J=0;J<3;J++)
{
scanf(“%d”,&C[I][J]);
}
}
for(I=0;I<3;I++)
{
for(J=0;J<3;J++)
{
D[I][J]=0;
for(K=0;K<3;K++)
{
D[I][J]=D[I][J]+A[I][K]*B[K][J];
}
D[I][J]=D[I][J]+C[I][K];
}
}
printf(“RESULT 3X3 MATRIX D VALUES ARE :\n”);
for(I=0;I<3;I++)
{
for(J=0;J<3;J++)
{
printf(“%d\t”,D[I][J]);
}
printf(“\n”);
}
getch();
}

Code:

 Source code
```#include<stdio.h>
void main()
{
int A[3][3],B[3][3],C[3][3],D[3][3],I,J,K;
clrscr();

for(I=0;I<3;I++)
{
for(J=0;J<3;J++)
{
scanf("%d",&A[I][J]);
}
}
printf("ENTER 3X3 MATRIX B VALUES\n");
for(I=0;I<3;I++)
{
for(J=0;J<3;J++)
{
scanf("%d",&B[I][J]);
}
}
printf("ENTER 3X3 MATRIX C VALUES\n");

}
}
printf("RESULT 3X3 MATRIX D VALUES ARE :\n");
for(I=0;I<3;I++)
{
for(J=0;J<3;J++)
{
printf("%d\t",D[I][J]);
}
printf("\n");
}
getch();
}```
