[Beginner's TuT] C++ - Area of Triangle

[Lakshay]

This is my Tutorial for Beginners - Area of Triangle.

#include <iostream>

using namespace std;

int main()
{
        //declare variables
        double lenght    = 0.0;
        double width     = 0.0;
        double area              = 0.0;

        //inpute items
        cout << "Enter lenght: ";
        cin >>    lenght;
        cout << "Enter width: ";
        cin >>  width;

        //Calculate Area
        area = width * lenght

        //Calculate
        cout << "Your area is: " << area << endl;

        return 0;
                // end of main function

wait wait wait...

triangle area is: x * y? LOL!

what about (x*y)/2 ?

and thats not a tutorial.. thats a piece of code that explains almost nothing..

Yep, he's right x * y = area of a cube/rectangle/square
Area of a triangle is: 0.5(x*y) or (x*y)/2
You also forgot the closing bracket '}' at the end of your source

Triangle area is not l * w. This is the area of a square. Other than that it is a good work, and you should make some more advanced tutorials. Try doing a tutorial that finds real roots of a quadratic equation... Good luck!
