Using sscanf() and sprintf()

• Convert the input string into integers h and m using sscanf().
• Convert h to what it would be were it minutes.
• Convert m to what it would be were it hours.
• Use sprintf() to convert the new h and m into a C-style string. Remember that the formatting string "%02d" will pad the integer to two digits and include leading zeros.
• If you return the C style string, the C++ compiler will automatically convert it into a C++ style string as its return value.
