Write a function good$\_$echo that reads a line from standard input and writes it to

standard output. Your implementation should work for an input line of arbitrary

length. 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. Refer to the definitions of the standard I$/$O

functions for documentation $[45,61].$
