Subtraction of two numbers In c programming

#include <stdio.h> #include <conio.h> void main() { int num1, num2, sum; clrscr (); printf("Enter first number: "); // Ask the user for two numbers scanf("%d", &num1); printf("Enter second number: "); scanf("%d", &num2); sum = num1 - num2; // Calculate the sum printf("The result is:%d", sum); // Display the result getch (); }

Output

Explanation of the Subtraction Program

This C program takes two numbers from the user and performs subtraction. It subtracts the second number from the first number and stores the result in a variable named sum.

The program uses basic input functions to read numbers and simple arithmetic to calculate the result. It is a straightforward example for beginners learning how to work with variables and operators in C.

What the Program Does

• Prompts the user to enter the first number (num1).
• Prompts the user to enter the second number (num2).
• Subtracts the second number from the first using sum = num1 - num2;.
• Displays the final result on the screen.
• Uses clrscr() to clear the screen (Turbo C function).
• Uses getch() to pause the output window.

Example Input

Enter first number: 15
Enter second number: 7

Example Output

The result is: 8

Summary:
This program performs a simple subtraction of two user-entered numbers. It demonstrates the use of variables, arithmetic operations, scanf(), printf(), and Turbo C screen control functions.
