How to perform this matrix integral?

Write a C program to perform matrix multiplication using array?

• Answer:

  #include <stdio.h> #include <conio.h> void multiplication(int x[],int y[]); void main (void) { int a[2][2],b[2][2],i,j,m,n; clrscr(); printf("Enter 2x2 matrix:\n"); for(i=0;i<2;i++) for(j=0;j<2;j++) scanf("%d",&a[i][j]); printf("\nEnter another 2x2 matrix"); for(m=0;m<2;m++) for(n=0;n<2;n++) scanf("%d",&b[i][j]); multiplication(a,b); getch(); } multiplication(int x[],int y[]) { int i,j,sum; sum=0; printf("The multiplication of both the matrices gives:\n"); for(i=0;i<2;i++) { for(j=0;j<2;j++) sum=sum+a[i][j]*b[j][i]; printf("%d\n",sum); } }
