The draw_line() function should take two parameters, with the first being the size of the line (i. the number of characters) and the second parameter being the character with which to draw the line. This character parameter should have a default value of an asterisk (8*9). Create a main() function which tests the draw_line() function with a single size parameter value and also with a size and character parameter values.
