C Program to find Sum of Odd Numbers from 1 to n

Prerequisites

Before starting with this tutorial, we assume that you are the best aware of the following C programming topics:

Operators in C Programming.

Basic Input and Output function in C Programming.
Basic C programming.
For loop in C programming.

Arithmetic operations in C Programming.

What is an Odd number?

A number is said to be an Odd number when that number is divided by two into two, not equal whole numbers. And there should not be a remainder of zero when it is being divided by 2.

Program to find Sum of Odd numbers up to a range.

In this program, we will first take the input point from the user. Then we will find the Odd numbers up to that range and add them to a variable. At last, we will print that sum.

With the help of this program, we can Print Sum of Odd numbers.

Program to print the sum of Odd numbers to n Point:-

/* C Program to find Sum of Odd Numbers from 1 to n */
#include <stdio.h>
 
int main()
{
    //Declaring the required variables for the program
    int i, no, oddsum = 0;
    
    //Taking the input numbers
    printf("Enter the value of no upto which we want to find the sum \n");
    scanf("%d", &no);
    
    //Generating the series upto no variable and finding the sum of odd numbers
    for (i = 1; i <= no; i++)
    {
        if (i % 2 != 0)
            oddsum = oddsum + i;
    }
   
    //Printing the sum of all the even numbers
    printf("Sum of all odd numbers = %d\n", oddsum);

    return 0;
}

/* C Program to find Sum of Odd Numbers from 1 to n */

#include <stdio.h>

int main()

{

//Declaring the required variables for the program

int i, no, oddsum = 0;

//Taking the input numbers

printf("Enter the value of no upto which we want to find the sum \n");

scanf("%d", &no);

//Generating the series upto no variable and finding the sum of odd numbers

for (i = 1; i <= no; i++)

{

if (i % 2 != 0)

oddsum = oddsum + i;

}

//Printing the sum of all the even numbers

printf("Sum of all odd numbers = %d\n", oddsum);

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

oddsum = it will hold the integer value for the sum of numbers.
i = it will hold the integer value.
no = it will hold the integer value of the input.

Input number from the user.

Program Logic Code.

Printing output sum of odd numbers.
