I need to write a code in c++ I have the example output of the actual output but I have no clue from where to begin coding.

As said in the instructions To make the class schedule I need two string vector: coureseCodes and courseNames. main Parameter: none, return value: 0 and purpose: loop through the user menu viewSchedule Parameters: codes and class names, Return value: None Purpose: display all the items in the vectors addlass Parameters: codes and class names (both by reference) Return: value 0 on successful and unsuccessful on 1 Purpose: add course to vectors, course only 4 character long. If its not return 1 and end function, if its add to the code vector, query for the course name and add to the name vector. Return 0 removeClass Parameters: code and class names (both by reference), return value: 0 on successful remove, 1 on unsuccessful remove Purpose: remove course from the vector, should not display the vectors here. Asks the user which item they like to remove, check to see if the number is valid, return 1 on invalid, remove positions from both and return 0 on valid welcome to the class schedule manager. 10.
