Question

Convert your algorithm into a C++ program. Your program should output the value of the longest side of the right-angled triangle.

Note, to answer the question, you will need to be able to do square root. To do square root, follow these 2 steps.

1) include the cmath library that allows square root using the statement

#include <cmath>

2) To perform a square root, use the syntax

sqrt(a double variable or number goes in here);

For example

cout << sqrt(25.0);   

OR

double answer = sqrt(25.0);

The first statement above will display 5 to the output screen and the second statement will store the 5 in a variable. Use whichever you like

Answer 1

C++ code:

#include <iostream>
#include <cmath>
using namespace std;
int main()
{
    //initializing two sides
    double side1,side2;
    //asking for their lengths
    cout<<"Enter the lengths of the other two sides: ";
    //accepting them
    cin>>side1>>side2;
    //printing the length of longest side by finding square root of both sides squared and added
    cout<<"The length of the longest side is "<<sqrt(side1*side1+side2*side2)<<endl;
    return 0;
}
