First Proper C++ Program

This is it, my first real C++ program. All it does is print pythagorean triples between 0 and 100, but I'm proud of it :D

// PythagoreanTriples.cpp : Defines the entry point for the console application.

//

#include "stdafx.h"

#include "cmath"

float calculateHypot(int a, int b) // calculates square root of a^2 + b^2

{

float c;

c = ((a*a)+(b*b));

return sqrt(c);

}

bool checkInteger(float a) // subtracts int-cast version of c from c to determine if integer

{

if(a-(int)a != 0) return true; // if floating value, return true

return false; // if integer value, return false

}

int _tmain(int argc, _TCHAR* argv[])

{

printf("***********************\n");

printf("* PYTHAGOREAN TRIPLES *\n");

printf("***********************\n");

int a;

int b;

//printf("The result is: %f", c);

for (a=1; a <= 100; a++)

{

for(b=1; b <= 100; b++)

{

float c = calculateHypot(a,b);

bool isInt = checkInteger(c);

if(isInt != true) // kinda reverse of what you'd think, but it only seems to work this way

{

int intC = int(c); // purely for display purposes - changes C into an integer value to cull trailing 0s

printf ("a = %d b = %d c= %d\n",a,b,intC);

}

}

}

}
