SCREEN LAYOUT / DESIGN

(Home Screen when programs runs. User can choose a, b, or c.)

Pythagorean Theorem

Compute for

[a] altitude

[b] base

[c] hypotenuse

Input [a| b |c]:_

(When c is clicked this screen/ layout below will be shown. If Y is inputted in the Try Another control, go back to screen 1 else program will exit.)

Pythagorean Theorem

Function 1 (find c)

Input a: 4

Input b: 3

Computed value of c: 5

Try Another [Y/N]:

(When a is clicked, do function 2, If b is clicked do function 3)

Pythagorean Theorem

Function 2 (find a)

Input c: 5

Input b: 3

Computed value of a: 4

Try Another [Y/N]:

Pythagorean Theorem

Function 3 (find b)

Input c: 5

Input a: 4

Computed value of b: 3

Try Another [Y/N]:

SOLUTION TO THE ABOVE QUESTION

SOLUTION CODE

#include<iostream>
#include <cmath>


using namespace std;

	//print our equation
	cout<<"\nOur equation is a2 + b2 = c2"<<endl;
	int terminate_condition = 1;
	while(terminate_condition==1)
	{
	 //propmt the user to enter the parameter he/she wants to find
	cout<<"\nCompute for: "<<endl;
	cout<<"[a] altitude"<<endl;
	cout<<"[b] base"<<endl;
	cout<<"[c] hypotenuse"<<endl;


    cout<<"Enter the parameter to find: ";
    string parameter;
    cin>>parameter;
    if(parameter == "a")

    	double c = (a*a)+(b*b);
    	c = sqrt(c);
    	cout<<"Computed value of c: "<<c<<endl;
	}
	else
	{
		cout<<"Invalid option, please try again"<<endl;
	}
	
	cout<<"Try another condition:"<<endl;
	cout<<"Enter Y for yes or N for No: ";
	string continue_option;
	cin>>continue_option;
	if(continue_option=="Y")
	{
