How to calculate profit or loss on any product using if else in C programming. Program to calculate profit and loss of any product in C. Logic to find profit or loss in C program.

## Logic to find profit or loss

In your primary mathematics classes, you all 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 profit. 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 code solution for 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;
}
```

Output

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

Happy coding 😉
