Write a program to calculate profit or loss

When selling price is less than cost price, then it is said to be profit else loss.

#include<stdio.h>

void main()

{

   int CP, SP, pro, loss;

   printf("Enter cost price and selling price of an object:");

   scanf("%d %d", &CP, &SP);

   if(SP>CP)

     { 

        pro = SP-CP;

        printf("\n Profit = Rs.%d", pro);

       }

else

     {

        loss = CP-SP;

        printf("\n Loss = Rs.%d", loss);

       }

}
