6. WRITE A C PROGRAM TO MULTIPLY TWO MATRICES THAT SATISFY

THE CONSTRAINT OF MATRIX MULTIPLICATION

SOURCE CODE:

#include<conio.h>

void main()

//clrscr();

printf("Enter 1st matrix size\n");

scanf("%d%d",&r1,&c1);

scanf("%d%d",&r2,&c2);

if(c1!=r2)

printf("Matrix multiplication is not possible\n");

else
