Left as much background information as I could. Those functions must be used when writing the code. i have the header code here:

#ifndef NSTEP_CODING #define NSTEP_CODING #include using std::string; #include using std::vector; string vec_2_str(const vector& v); vector gen_nstep_vector (long limit, long nstep); string num_to_nstep_coding(long num, long nstep); long nstep_coding_to_num(const string& coding, const vector& nstep_sequence); #endif 

You can make the main.cpp, but in the end all I need is the functions.cpp code. Thank you
