i need these functions weitten in C++ using knly bitwise operators.

i need these in C++ using bitwise operaters please!

byte str2bin(string &) - required Given a binary number as an ASCII string, this function computes and returns the corresponding uhsigned char. Seek inspiration from Lab 1. Replace multiplication with bit-shifting and use bitwise OR in addition when setting a bit. - string bin2str(byte) -- required This function does the reverse of the strin function. That is given an unsigned char, it computes and returns the corresponding ASCII string. Use bitwise operations to determine when and how to set a b
