C++ Here is the original question for what it is worth. Please do not give me an answer you found on Chegg. I have one of those accounts too. Please read carefully, I have submitted this question several times and no one could follow directtions. I have my code doing what is asked of the problem with the exception of displaying the last_name, first_name A teacher is requiring her students to line up in alphabetical order, according to their first names..For example, in one class Chapel, Christine would be at the front and Uhura, Nyota would be last. The program will get the names from a file using getline since the file name includes spaces. The names should be read in until there is no more data to read. The program should prompt the user for the file name and read the data from the file. Note that these names might include spaces; handle your input accordingly. The expected output is two names; do not show the entire file.  Do not use arrays or sorting for this problem.   Here is my…

In C++: Print a table that prompts the user to enter the current tuition and displays a table that displayshow many years the tuition will be doubled if the tuition is increased by 5%, 6%, and up to 10%annually. Here is a sample run: Enter the current year tuition: 20000 Rate   Number of Years 5.0%   15 6.0%   12 7.0%   11 8.0%   10 9.0%     9 10.0%   8  1. Add comments throughout the program explaining your code.2. Use meaningful names for variable names.3. Submit program in .cpp file

Code in C++ please, with comments to guide the code.
