Sum of n natural numbers || do while loop || C++

In this, we are going to see do-while loop, the program is based on do-while loop which prints, sum of 1 to n numbers.

The code given below can be used for TURBO C++ Compiler:-

    #include<iostream.h>
#include<conio.h>

void main()
{
    clrscr();
    int n, i = 1;
    int sum = 0;
    cout << "Enter value of n to find sum upto that number\n";
    cin >> n;
    do
    {
        sum = sum + i;
        i++;
    } while (i <= n);
    cout << "Sum of " << n << " natural numbers is " << sum;
    getch();
}

The code given below can be used for g++/gcc Compiler:-

    #include<iostream>
using namespace std;

int main()
{
    int n, i = 1;
    int sum = 0;
    cout << "Enter value of n to find sum upto that number\n";
    cin >> n;
    do
    {
        sum = sum + i;
        i++;
    } while (i <= n);
    cout << "Sum of " << n << " natural numbers is " << sum;
    return 0;
}
