(Sides of a Right Triangle) Write a program that reads three nonzero integers and deter- mines and prints whether they could be the sides of a right triangle.

Question

What will be an ideal response?

Answer 1

```
// Determine whether three values represent the sides of a right triangle.
#include
using namespace std;

int main()
{
int side1; // length of side 1
int side2; // length of side 2
int side3; // length of side 3
bool isRightTriangle = false; // if sides can form right triangle

// get values of three sides
cout << "Enter side 1: ";
cin >> side1;

cout << "Enter side 2: ";
cin >> side2;
cout << "Enter side 3: ";
cin >> side3;

// square the sides
int side1Square = side1 * side1;
int side2Square = side2 * side2;
int side3Square = side3 * side3;

// test if sides can form a right triangle
if ( ( side1Square + side2Square ) == side3Square )
isRightTriangle = true;
else if ( ( side1Square + side3Square ) == side2Square )
isRightTriangle = true;
else if ( ( side2Square + side3Square ) == side1Square )
isRightTriangle = true;

// display results
if ( isRightTriangle )
cout << "These are the sides of a right triangle." << endl;
else
cout << "These do not form a right triangle." << endl;
} // end main
