Algorithm to Check Whether a Number is Even or Odd

Use the following algorithm to write a program to check whether a number is even or odd; as follows:

  • Step 1: Start Program
  • Step 2: Read the number from user and store it in a.
  • Step 3: Find the number is even or odd using a % 2 == 0.
  • Step 4: Print number is even or odd
  • Step 5: Stop Program

C Program to Check Even or Odd

#include <stdio.h>
int main() {
    int num;
    printf("Enter an integer: ");
    scanf("%d", &num);

    // true if num is perfectly divisible by 2
    if(num % 2 == 0)
        printf("%d is even.", num);
    else
        printf("%d is odd.", num);
    
    return 0;
}

The output of the above c program; as follows:

Enter an integer: 10
10 is even.

C Program to Check Whether a Number is Even or Odd using Function

#include <stdio.h>
#include <stdlib.h>
int find_Num(int);//function prototype
int main()
{
    int num;
    printf("Enter a number to check odd or even :- ");
    scanf("%d",&num);
    find_Num(num);//calling the function
    return 0;
}
//create function
int find_Num(int num){//function definition
if(num%2==0){
    printf("\n%d is an even number",num);
}
else{
    printf("\n%d is an odd number",num);
}
}

The output of the above c program; as follows:

Enter a number to check odd or even :- 11
11 is an odd number

C Program to Check Whether a Number is Even or Odd using Ternary Operator

#include <stdio.h>
int main() {
    int num;
    printf("Enter an integer: ");
    scanf("%d", &num);
    
    (num % 2 == 0) ? printf("%d is even.", num) : printf("%d is odd.", num);
    return 0;
}

The output of the above c program; as follows:

Enter an integer: 15
15 is odd.
