• Exercise 3: Write a program called multi_input.cpp that prompts the user to enter several integers in any combination of octal, decimal, or hexadecimal, using the 0 and 0x base suffixes; interprets the numbers correctly, and converts them to decimal form. Then your program should output the values in properly spaced columns like this:

            0x4 hexadecimal converts to     67 decimal
           0123 octal       converts to     83 decimal
             65 decimal     converts to     65 decimal
  

  Solution code.

• Exercise 9: Write a function vector split(const string& s) that returns a vector of whitespace-separated substrings from the argument s.

  Solution code.

• Exercise 12: Reverse the order of words (defined as whitespace separated strings) in a file. For example, Norwegian Blue parrot becomes parrot Blue Norwegian. You are allowed to assume that all the strings from the file will fit into memory at once.
