Question 2 25 points Write a C function, with appropriate comments to explain how your code works, to scan a null-terminated string and return a pointer to the first non-whitespace" character in the string. If the string is entirely whitespace, then return a pointer to the terminating null character. For this exercise, whitespace includes spaces, tabs ('\t"), newlines (' '), and shell-style comments (between "#" and newline). The function prototype should be const char* skipSpaces(const char* buffer); and as an illustrating example, should return the following pointers p for the buffers shown below: " \t 4" 1 1 buffer P 11 "# All whitespace 1 buffer # Another # one It # This is a comment 1 buffer here \t % #" 1 You may not call any other functions, except for helper functions you provide. You will lose points for inefficiency (c.g., scanning the string more than once)
