Logic to find profit or loss

In your primary mathematics classes, you have learnt about profit and losses. Here goes the basic definitions for profit and loss. If the cost price is greater than selling price then there is a loss otherwise. Basic formula to calculate profit and loss
Profit = S.P - C.P (Where S.P is Selling Price and C.P is Cost Price)
Loss = C.P - S.P

After quick recap of profit and losses let us write down a step by step descriptive logic of the program.

Program to calculate profit or loss

/**
 * C program to calculate profit or loss
 */

#include <stdio.h>

int main()
{
    int cp,sp, amt; 
    
    /* Reads cost price and selling price of a product */
    printf("Enter cost price: ");
    scanf("%d", &cp);
    printf("Enter selling price: ");
    scanf("%d", &sp);
    
    if(sp > cp)
    {
        //Profit
        amt = sp - cp;
        printf("Profit = %d", amt);
    }
    else if(cp > sp)
    {
        // Loss
        amt = cp - sp;
        printf("Loss = %d", amt);
    }
    else
    {
        // Neither profit nor loss
        printf("No Profit No Loss.");
    }

    return 0;
} 

Enter cost price: 1000
Enter selling price: 1500
Profit = 500

Happy coding ;)
