Coding assembly concepts in C++

The following will require Assembly language and C++

Write one C++ code as single cpp file with the following functions:

Function to convert a string (such as 100) into decimal number

Function to take a float number and extract the sign/fraction and exponent from IEEE standard float

Function to set a specific bit to either 1 or 0

and Function to display the bit pattern for a given number (should be able to read each bit check if it's zero or one) and display.

Comments explaining what is going in will greatly assist me, I will give best rating.
