Find odd or even number using switch statements in C

Find the odd or even number using switch statements in C

In this tutorial, we will discuss the concept of the find the odd or even number using switch statements in C language.

In this post, we are going to learn how to find odd or even number using switch statements in C programming language

when you devide a number by two and if the balance is zero, it is an even number

when you divided a number by two and if the balance is one, it is an odd number

Find the odd or even number — Find odd and even number

Example of even number 2,4,6,8,…..

Example of odd number 1,3,5,7,…..

Here, we will use a modular operator to display odd or even number of the given number

if n%2==0, n is a even number

if n%2==1, n is a odd number

Program to Find the Even number – Standard method

The program will check and display the even numbers from the given number using switch statements in C

Program 1

//C program to check whether number is EVEN using switch
#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num1=450;
    //int num2=561;
switch(num1%2){//this will return either 0 or 1
case 0:
    printf("%d is a even number",num1);
    break;
case 1:
    printf("%d is a odd number",num2);
}
getch();
    return 0;
}

When the above code is executed, it produces the following results

450 is an Even number

Program to Find the odd number – Standard method

The program will check and display the odd numbers from the given number using switch statements

Program 2

//C program to check whether number is ODD using switch
#include <stdio.h>
#include <stdlib.h>

int main()
{
    //int num1=450;
    int num2=561;
switch(num2%2){//this will return either 0 or 1
case 0:
    printf("%d is an even number",num1);
    break;
case 1:
    printf("%d is an odd number",num2);
}
getch();
    return 0;
}

When the above code is executed, it produces the following results

561 is an odd number

Program to Find the odd or Even number – Entered by user

This program allows the user to enter a number and then, the program will check and display the odd or even numbers from the given number using switch statements in C language

Program 3

//C program to check whether number is EVEN or ODD using switch
#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num;
    printf("Enter the number\n");
    scanf("%d",&num); //this will return either 0 or 1

    switch(num%2){
case 0:
    printf("%d is a even number",num);
    break;
case 1:
    printf("%d is a odd number",num);
}
getch();
    return 0;
}

When the above code is executed, it produces the following results

Case 1

Enter the number
35
35 is a odd number

Case 2

Enter the number
50
50 is a even number

Approach

The modular operator uses to find the modulus of the number dividing by 2.
Switch statements return either 0 or 1.
Then, check the case value with 0 or 1.
if the case value is 0, the number will be even and case value 1, the number will be odd.
