Edit: I figured out how to do everything and it works, but my area for the triangle part keeps giving me values of 0 for every answer.

The program is a Geometry calculator, works perfectly.

Code:

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

int loop=1;

int choice;

while (loop==1)

{

system("CLS");

cout << "::Geometry Calculator::\n\n"

<< "1. Area of a Circle\n"

<< "2. Area of a Triangle\n"

<< "3. Exit\n\n";

cin >> choice;

switch(choice)

{

case 1:

system("CLS");

double pi, radius, area;

cout << "::Area of a Circle::\n\n"

<< "Enter your radius: ";

cin >> radius;

pi = 3.14159;

area = pi * (radius*radius);

cout << "The area of the circle is " << area << "." << endl;

system("PAUSE");

}

switch(choice)

{

case 2:

if(choice==2)

system("CLS");

int base, height, a2;

cout << "::Area of a Triangle::\n\n"

<< "Enter your base: ";

cin >> base;

cout << "Enter your height: ";

cin >> height;

a2 = 1/2 * base * height;

cout << "Your result is " << a2 << "." << endl;

system("PAUSE");

}

switch(choice)

{

case 3:

if(choice==3)

system("CLS");

cout << "Adios!!\n\n";

system("PAUSE");

exit(0);

}

}

}

If anyone knows why I keep getting zeros for the triangle part, please help.

Thank you!

(base * height) / 2 |

This may not always be accurate as base and height are both declared as type int and the magic number 2 is written as an int so if there is a remainder it will be lopped.

Sorry for the late response, but I was able to get it bout 5 minutes after I posted.

But I did try your way, and it worked the same. Thank you for your help anyways!
