Question #2: Study the following C program and answer the below questions Hint: you might run it in Dev C++ before starting answering the questions! a) Show a sample output of the program. b) Extract a function declaration (prototype) for: 1) void functions with void argument 2) void function with a single input argument 3) function with a single input argument and return 4) a recursive function c) What is the difference between normal functions and recursive functions? d) How many times are the function print_stars() called in the program? (mention the line number of each call).
