C program for "Any integer is input through keyboard. write a program to find out whether it is an odd number or even number."

Problem: C program for "Any integer is input through keyboard. write a program to find out whether it is an odd number or even number." 

Logic used :

• Find the remainder of the number using modulus operator with 2.
• If the remainder is equal to 0, the number is even.
• If the remainder is not equal to 0, the number is odd.

Demo :

if(num%2 == 0){

        printf("%d is even.",num);

    }else{

        printf("%d is odd.",num);

    }

C program :

// Program by Shyam Kanth

#include<stdio.h>

int main(){

    int num;

    printf("Enter the number : ");

    scanf("%d",&num);

    if(num%2 == 0){

        printf("%d is even.",num);

    }else{

        printf("%d is odd.",num);

    }

    return 0;

}

Codes used :

• #include < stdio.h > : Header file for input-output
• int : Integer data type
• num : Variable used
• printf : Function for displaying message
• scanf : Function for taking input
• if-else : Conditional statement
• %d : Format specifier for integer type data
