Hi and a question

Hi everyone, im relatively new to programming.

I'm having an issue with some code ive written, after the program opens and I input my first bit of data, it closes down and i'm having trouble keeping it open

Thanks for any suggestions/help

Code:

#include "stdafx.h"
#include <iostream>
#include <cmath>
#include <cstdlib>
#include <cfloat>
#include <iomanip>
#include <stdlib.h>
#include <time.h>
#include <conio.h>


using namespace std;


float doBreak ();
float doProbability (float, float);


const int SENTINEL = 21;		//sentinal value




int main()
{
	float count;
	float tests;
	float probability;
	float triangle = 0;
	


	count = 1;
	srand (time (NULL));


	cout << "Enter number of glassrods to demolish (Enter " << SENTINEL << " to end program): ";
	cin >> tests;


	if 
	(tests != SENTINEL)
	{
		do
		{
			triangle = triangle + doBreak();
			count++;
		}while (count <= tests);


	probability = doProbability(triangle, tests);
	
	cout << "The probability that the broken glass rods will form a triangle is: " << probability << "%" << endl;
	}
	else
	{
			cout << "Aww, I was hoping to break stuff..." << endl;
	}
	return 0;
}


float doBreak()
{
	float break1;
	float break2;	
	float side1;
	float side2;
	float side3;
	
	
	
	
		
	break1 = (float)rand()/RAND_MAX;
	break2 = (float)rand()/RAND_MAX;
	
	if (break1 < break2)
	{
		side1 = break1;
		side2 = (break2 - break1);
		side3 = 1 - break2;
	}
	else
	{	
		side1 = break2;
		side2 = (break1 - break2);
		side3 = 1 - break1;
	}
	if
	((side1 + side2) > side3 &&
	(side1 + side3) > side2 &&
	(side2 + side3) > side1)
	{
		return 1;
	}
	else
	{
		return 0;
	}
}
	
float doProbability 
	(float triangle,
	float tests)
	
{
	float probability;
	
	probability = (triangle / tests) * 100;
	return probability;
}

? anybody

Also, your IDE may have a "keep window open at program exit", which is preferred, since it doesn't involve you changing your source code.
