Design a class to overload a function polygon() as follows:
- void polygon(int n, char ch) — with one integer and one character type argument to draw a filled square of side n using the character stored in ch.
- void polygon(int x, int y) — with two integer arguments that draws a filled rectangle of length x and breadth y, using the symbol '@'.
- void polygon() — with no argument that draws a filled triangle shown below:
Example:
- Input value of n=2, ch = 'O'
Output:
OO
OO - Input value of x = 2, y = 5
Output:
@@@@@
@@@@@ - Output:
