Print Even and Odd Numbers in C

In C programming, you can determine whether a number is even or odd using the modulus operator (%). Even numbers are divisible by 2, while odd numbers are not.

1. Problem Statement

Write a C program that takes an integer input from the user and prints whether it is even or odd.

2. Algorithm

Step 1: Start the program.

Step 2: Declare an integer variable to store the number.

Step 3: Read the number from the user.

Step 4: Check if the number % 2 equals 0.

Step 5: If yes, print 'Even number', else print 'Odd number'.

Step 6: End the program.

3. C Program

C
Program to print whether a number is even or odd 
#include <stdio.h>

int main() {
    int num;

    printf("Enter a number: ");
    scanf("%d", &num);

    if(num % 2 == 0) {
        printf("%d is an Even number", num);
    } else {
        printf("%d is an Odd number", num);
    }

    return 0;
}

4. Example

Input:
Enter a number: 7
Output:
7 is an Odd number

Notes

Even numbers are divisible by 2 without remainder. Odd numbers have a remainder of 1 when divided by 2. The modulus operator (%) is used to determine this in C.
