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; }
