 #include <stdio.h>
int main(){
    // code to multipy a and b without using *--
    float a,b,c=0;
    printf("Enter first operand: ");
    scanf("%f",&a);        
    printf("Enter second operand: ");
    scanf("%f",&b);
    // a*b means a+a+a+a+...b times--
    for(int i=1;i<=b;i++){
        c=c+a;
    }
    printf("Product is %.2f\n",c);
         return 0;
