Description

Program to check whether 3 values represent a right triangle.

Demo Code

#include <math.h>
#include <stdio.h>
#include <iostream>
#include <algorithm>

bool isRightTriangle(int, int, int);

int main(int argc, const char *argv[]) {
    int a, b, c = 0;

    std::cout << "Enter three space separated non zero integers: ";
    std::cin >> a >> b >> c;

    printf("%d %d %d could%srepresent a right triangle.\n", a, b, c,
           (isRightTriangle(a, b, c)) ? " " : " not ");
    return 0;//w  w  w . j a v a2s .com
}
bool isRightTriangle(int a, int b, int c) {
    int hypotenuse = std::max(a, std::max(b, c));

    if (hypotenuse == a)
        return pow(b, 2) + pow(c, 2) == pow(hypotenuse, 2);
    else if (hypotenuse == b)
        return pow(a, 2) + pow(c, 2) == pow(hypotenuse, 2);
    else
        return pow(a, 2) + pow(b, 2) == pow(hypotenuse, 2);
}
