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;
}
OUTPUT
ANALYSIS
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("\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
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("\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;
}
OUTPUT
