I need this in C. Here's is the provide code. The character should be randomize in a box like rectangle.

ASCII Art Generator (16 pts.) Now to have some fun with loops! Write a program that first gets a number of columns C and lines L from the user and then creates an ASCII pattern that is L C characters large. Your program should use nested loops, if statements, and randomness. Don't copy the example below - be creative with your pattern! $./main Welcome to the ASCII art generator! Enter the number of columns: 10 Enter the number of rows: 8 \#\#\#\#\#\#\#\#\#\# \#/ #\/\/\# #/\\//# #\///\ \#\#\#\#\#\#\#\#\#\# Challenge (optional!) Instead of a random pattern, can you make your program generate an ASCII art picture of an object of the given size? For example, an LC tree or flower
