Write a function good_echo that reads a line from standard input and writes it to stan- dard output. Your implementation should work for an input line of arbitrary length. Also include a main routine that can be run to test the function. You may use the library function fgets, but you must make sure your function works correctly even when the input line requires more space than you have allocated for your buffer. Your code should also check for error conditions and return when one is encountered. You may see documentation for standard I/O functions with a command like man fgets
