**C program to calculate profit or loss**

Write a C program to input cost price and selling price of a product and check profit or loss. Also calculate total profit or loss using if else. 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.

**Example**

**Input**

Input cost price: 1000

Input selling price: 1500

**Output**

Profit: 500

**Required knowledge**

Basic C programming, Relational operators, If else

**Logic to find profit or loss**

In primary mathematics classes, you all have learned about profit and loss. If cost price is greater than selling price then there is a loss otherwise profit.

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 loss 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; /* Input 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) { /* Calculate Profit */ amt = sp - cp; printf("Profit = %d", amt); } else if(cp > sp) { /* Calculate 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
