Algorithm to Print Even Numbers from 1 to N

Follow the below given algorithm to write a program to print even numbers from 1 to N (10, 100, 500, 1000):

  • Step 1: Start writing program
  • Step 2: Read the number from user and store it in a.
  • Step 3: Iterate for or while loop according to a user input a number.
  • Step 4: Inside loop, use if with n % 2 == 0 condition to print even number.
  • Step 5: Stop Program

C Program to Print Even Numbers from 1 to N using For Loop

/* C Program to Print Even Numbers from 1 to N using For Loop and If */
 
#include<stdio.h>
 
int main()
{
  	int i, number;
 
  	printf("\n Please Enter the Maximum Limit Value : ");
  	scanf("%d", &number);
  
  	printf("\n Even Numbers between 1 and %d are : \n", number);
  	for(i = 1; i <= number; i++)
  	{
    	if ( i % 2 == 0 ) 
    	{
  			printf(" %d\n", i);
    	}
  	}
 
  	return 0;
}

The result of the above c program; as follows:

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 N using While Loop

#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\n", i);
		i = i+2;
  	}
 
  	return 0;
}

The result of the above c program; as follows:

Please Enter the Maximum Limit Value : 15
Even Numbers between 1 and 15 are : 
 2
 4
 6
 8
 10
 12
 14

C Program to Print Even Numbers from 1 to N using Function

/* C Program to Print Even Numbers from 1 to N using For Loop and If */
 
#include<stdio.h>
int evenNoList(no){
    
int i;
  for(i = 1; i <= no; i++)
  {
    if ( i % 2 == 0 ) 
    {
      printf(" %d\n", i);
    }
  }
}
int main()
{
  	int number;
 
  	printf("\n Please Enter the Maximum Limit Value : ");
  	scanf("%d", &number);
    printf("\n Even Numbers between 1 and %d are : \n", number);
    evenNoList(number);
    return 0;
}

The result of the above c program; as follows:

Please Enter the Maximum Limit Value : 20
Even Numbers between 1 and 20 are : 
 2
 4
 6
 8
 10
 12
 14
 16
 18
 20
