Checking of even or odd number (if...else) in c programming

#include <stdio.h> #include <conio.h> void main() { int num, rem; clrscr(); printf("Enter a number: "); scanf("%d", &num); rem = num % 2; if (rem==0) { printf("The number is even"); } else { printf("The number is odd"); } getch(); }

Output

Explanation of the Even-Odd Checking Program

This C program checks whether a number entered by the user is even or odd. The program uses the modulus operator (%) to find the remainder when the number is divided by 2.

If the remainder is 0, the number is even. Otherwise, the number is odd. This is determined using a simple if–else statement.

What the Program Does

• Asks the user to enter any integer number.
• Calculates the remainder using num % 2.
• If remainder is 0, prints "The number is even".
• If remainder is 1, prints "The number is odd".
• Uses clrscr() to clear the screen (Turbo C function).
• Uses getch() to pause the output window.

Example Input -1

Enter a number: 14

Example Output -1

The number is even

Example Input -2

Enter a number: 15

Example Output -2

The number is odd

Summary:
This program determines whether a number is even or odd by checking the remainder when divided by 2. It demonstrates the use of conditional statements, arithmetic operators, and basic input/output operations in C programming.
