C Program to Print Sum of all Even Numbers

How to write a C Program to Print Sum of all Even Numbers using If Statement with an example.

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

This program allows the user to enter the maximum limit value. Next, this C Program finds the Sum of all Even Numbers in a given range.

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

/* 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;
}

Within this C Program to find Sum of all Even Numbers from 1 to N , 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 checks 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 C Programming compiler will add i value to sum.

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

This program to find Sum of all Even Numbers is the 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("\nPlease Enter the Maximum Limit Value :");
  scanf("%d", &number);
  
  printf("\nEven Numbers between 0 and %d are : ", number);
  for(i = 2; i <= number; i=i+2)
  {
    Sum = Sum + i;
    printf("%d  ", i);
  }
  printf("\nThe Sum of All Even Numbers upto %d  = %d", number, Sum);

  return 0;
}

C sum of even numbers from 1 to n using for loop output

Please Enter the Maximum Limit Value :20

Even Numbers between 0 and 20 are : 2  4  6  8  10  12  14  16  18  20  
The Sum of All Even Numbers upto 20  = 110

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 C 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("\nPlease Enter the Minimum, and Maximum Limit Values :\n");
  scanf("%d %d", &Minimum, &Maximum);
  
  printf("\nEven Numbers between %d and %d are : ", Minimum, Maximum);
  for(i = Minimum; i <= Maximum; i+=2)
  {
    printf("%d  ", i);
    Sum = Sum + i;
  }
  printf("\n\nThe Sum of All Even Numbers betwen %d and %d  = %d", Minimum, Maximum, Sum);

  return 0;
}

Please Enter the Minimum, and Maximum Limit Values :
10
100

Even Numbers between 10 and 100 are : 10  12  14  16  18  20  22  24  26  28  30  32  34  36  38  40  42  44  46  48  50  52  54  56  58  60  62  64  66  68  70  72  74  76  78  80  82  84  86  88  90  92  94  96  98  100  

The Sum of All Even Numbers betwen 10 and 100  = 2530
