C Program to Print Even Numbers from 1 to 100 using While Loop:

Below mentioned program is used to print even numbers from 1 to N using the while loop. The value of N is asked by users with the help of a scanf (input) function.

#include<stdio.h>
int main()
{
    int i = 2, number;
    printf("\n Please Enter the Maximum Limit Value : ");
    scanf("%d", &number);
    printf("\n Even Numbers between 1 and %d are : \n", number);
    while(i <= number)
    {
        printf(" %d\t", i);
        i = i+2;
    }
    return 0;
}

Output:

Please Enter the Maximum Limit Value: 10

Even Numbers between 1 and 10 are :
2 4 6 8 10

C Program to Print Even Numbers from 1 to 100 using for Loop:

Below mentioned program is used to print even numbers from 1 to N using the for a loop. The value of N is asked by users with the help of a scanf (input) function.

#include<stdio.h>
int main()
{
    int i, number;
    printf("Please Enter the Maximum Limit Value : ");
    scanf("%d", &number);
    printf("Even Numbers between 1 and %d are : \n", number);
    for(i = 1; i <= number; i++)
    {
        if ( i % 2 == 0 )
        {
            printf(" %d\t", i);
        }
    }
    return 0;
}

Output:

Please Enter the Maximum Limit Value: 10

Even Numbers between 1 and 10 are :
