C Program to Print Sum of all Even Numbers

In this article, we will show you, How to write a C Program to Print Sum of all Even Numbers using If Statement with an example.

TIP: We already explained the logic to check whether the given is Even or Not in C Program to Check Odd or Even article. I suggest you to refer the same.

C Program to Print Sum of all Even Numbers from 1 to n

This program allows the user to enter the maximum limit value.

/* C Program to Print Sum of all Even Numbers from 1 to N */
 
#include<stdio.h>
 
int main()
{
  int i, number, Sum = 0;
 
  printf("\n Please Enter the Maximum Limit Value : ");
  scanf("%d", &number);
  
  printf("\n Even Numbers between 0 and %d are : ", number);
  for(i = 1; i <= number; i++)
  {
    if ( i%2 == 0 ) //Check whether remainder is 0 or not
    {
  	printf("%d  ", i);
        Sum = Sum + i;
    }
  }
  printf("\n The Sum of All Even Numbers upto %d  = %d", number, Sum);

  return 0;
}

OUTPUT

ANALYSIS

Here, For Loop will make sure that the number is between 1 and maximum limit value.

for(i = 1; i <= number; i++)

In the Next line, We declared the If statement

if ( number % 2 == 0 )

Any number that is divisible by 2 is even number. If condition will check whether the remainder of the number divided by 2 is exactly equal to 0 or not. If the condition is True then it is Even number, and the compiler will add i value to sum.

C Program to Print Sum of all Even Numbers from 1 to n

This program is same as above but we altered for loop to eliminate the If statement.

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

  return 0;
}

OUTPUT

C Program to Print Sum of all Even Numbers in a Given Range

This C program allows the user to enter Minimum and maximum value. Next, the program will calculate the sum of even numbers between Minimum value and maximum value.

/* C Program to Print Sum of all Even Numbers in a Given Range */
 
#include<stdio.h>
 
int main()
{
  int i, Minimum, Maximum, Sum = 0;
 
  printf("\n Please Enter the Minimum, and Maximum Limit Values : \n");
  scanf("%d %d", &Minimum, &Maximum);
  
  printf("\n Even Numbers between %d and %d are : ", Minimum, Maximum);
  for(i = Minimum; i <= Maximum; i+=2)
  {
    printf("%d  ", i);
    Sum = Sum + i;
  }
  printf("\n\n The Sum of All Even Numbers betwen %d and %d  = %d", Minimum, Maximum, Sum);

  return 0;
}
