Task
In this first tutorial, we start with the introduction of different data structures, such as list, vector, and map. Write a program which can handle the following tasks:
 | Reserve memory for three two-dimensional points in coordinate representation. Use floating point numbers with double precision.
|
| Assign useful values to each of the double variables according to point coordinates.
|
| Write a function which takes the six values of the points and returns the area of the triangle.
|
| Print the area of the triangle on the screen. |
