C program to display all odd or even numbers 1 to n with label

In this article, we will discuss the concept of C program to display all odd or even numbers from 1 to n with label using loops

In this post, we will learn how to find and display odd and even numbers from 1 to n with label using the loops.

Here, we will use for loop, while loop and do-while loop to find and display odd and even numbers from 1 to n in C programming language.

C program to display the odd or even numbers with label using loops

Using for loop

program 1

This program allows the user to enter the maximum numbers. It finds and displays even and odd numbers with the label from 1 to entered number using for loop.

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num,i;
    printf("Enter the random number \n");
    scanf("%d",&num);//Takes input from the user

    printf("Display all odd and even number till %d",num);

printf("\n\n");

for(i=1; i<=num; i++){
    if(i%2==0){//Using modular operator to find odd or even
        printf("%d",i);
                printf(" Is Even");
        printf("\t");
    }

    else{
        printf("%d",i);
                printf(" Is Odd\t");
    }

}
getch();
    return 0;
}

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

Using while loop

program 2

This program allows the user to enter the maximum numbers. It finds and displays even and odd numbers with label 1 to entered number using while loop.

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num,i;
    printf("Enter the random number \n");
    scanf("%d",&num);

    printf("Display all odd and even number till %d",num);

printf("\n\n");

i=1;
while( i<=num){
    if(i%2==0){
        printf("%d",i);
                printf(" Is Even");
        printf("\t");
    }

    else{
        printf("%d",i);
                printf(" Is Odd\t");
    }
     i++;

}
getch();
    return 0;
}

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

Using do-while loop

Program 3

This program allows the user to enter the maximum numbers. It finds and displays even and odd numbers with label 1 to entered number using do-while loop.

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num,i;
    printf("Enter the random number \n");
    scanf("%d",&num);

    printf("Display all odd and even number till %d",num);

printf("\n\n");

i=1;
do{
    if(i%2==0){
        printf("%d",i);
                printf(" Is Even");
        printf("\t");
    }

    else{
        printf("%d",i);
                printf(" Is Odd\t");
    }
     i++;

}while( i<=num);
getch();
    return 0;
}

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