IN C++ PLEASE!!

5. Write a C/C++ program, say, graycode, that reads in a positive integer as n and prints out an n-bit graycode along with the corresponding decimal numbers. For example, $./graycode 3 3-bit gray code: Decimal Gray Code 000 001 2 011 3 010 4 110 5 111 101 7 100 (Hint: The simplest way to do this is to declare a string vector: vector v; Start with 1-bit code, consisting of only "0" and "1". Then append "0" to each v[i] and create another string "1" + v[i] and use push_back() to insert it into the vector.)
