__A NEW GAME__

__A NEW GAME__

*THE CWG 2010 committee is bored with the usual long jump, high jump and triple jump and they have*

*decided to introduce a new game called staircase climbing. The players need to climb a staircase. There are*

*n steps and each step is 1 meter higher than the previous one. The player who first reaches the top of the*

staircase will be declared as the winner.

*The audio-visual committee is responsible for placing pan and tilt cameras at all locations and one of their*

*main objective is to capture the winning moment in all the games. They were pondering on where to place*

*the camera for capturing the winning moment of the staircase climbing game. Finally, they decided on*

placing the camera at the same height as the top of the staircase.

*
*

Given the number of steps 'n' and the height of the first step 'h', write a C program to find the position

*where the camera needs to be placed.*

**Input Format:**

The input consists of 2 integers which correspond to n and h.

**Output Format:**

Output consists of a single integer.

**Sample Input 1:**

5

1

**Sample Output 1:**

15

**Solution:**

**#include<iostream>**

**#include<stdio.h>**

using namespace std;

int main()

{

int n, h, i, sum = 0;

cin >> n;

cin >> h;

for(i = 0; i < n; i++)

{

sum = sum + (h++);

}

cout << sum << '\n';

return 0;

}
