C Program to Add n Numbers

Prerequisites

Before starting with this tutorial we assume that you are 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.

Program to Add n Numbers

In c programming, it is possible to take numerical input from the user and Add n Numbers with the help of a very small amount of code. The C language has many types of header libraries which has supported function in them with the help of these files the programming is easy. In C language, we can do many arithmetic operations.

With the help of this program, we can Add n Numbers.

Here,

We will first take the input

The second will make a series and add the numbers.

Algorithm:-

1. Declaring the variables for the program.

2. Taking the input number from the user.

3. Passing that number to a for loop.

4. Adding the series to a variable.

5. Printing the result numbers.

6. End Program.

1. Declaring the variables for the program.

6. End Program.

Program to Add n Numbers:-

#include <stdio.h>
int main() 
{
    //declaring the variables for the program.
    int no, i, sum = 0;

    //taking input from the user a positive number
    printf("Enter any positive integer value : ");
    
    //scanning the input from the user.
    scanf("%d", &no);

    //using the for loop for the calculating the sum of n numbers
    for (i = 1; i <= no; ++i) {
        sum += i;
    }
    
    //Printing the output Sum for the n nubers
    printf("Sum = %d", sum);
    return 0;
}

#include <stdio.h>

int main()

{

//declaring the variables for the program.

int no, i, sum = 0;

//taking input from the user a positive number

printf("Enter any positive integer value : ");

//scanning the input from the user.

scanf("%d", &no);

//using the for loop for the calculating the sum of n numbers

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

sum += i;

}

//Printing the output Sum for the n nubers

printf("Sum = %d", sum);

return 0;

}

Output:-

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

no = it will hold the integer value.
i = it will hold the integer value.

sum = it will hold the integer value.

Input number from the user.
