# How to get feedback over multiple solutions of a particular exercise of a book?

I am self studying C++ from Robert Lafore's OOP in C++. I am solving the exercise questions of chapter-3 loop and decisions. For the first question(say X) I've written three different codes using different approaches(y1, y2 nd y3). I want to get feedback over my codes like a teacher is supposed to give feedback to his student. I want to get feedback over each code individually and then want to know which solution is overall better or more efficient.

The problem is how do I ask it so as it'd fit the Q&A format of SE. I've following options in mind:

• Post all the three codes y1, y2 and y3 in one question and ask -- For sure everything would mud up.
• Ask four different questions. First three for y1, y2 and y3's individual feedback and fourth one giving links to all three and asking which approach is best.

I think the second option is ok but if there is anything I need to keep in mind or any guidlines? E.g. should I first disclose at the beginning of each question that it is a part of four similar questions?

P.S: I've solved the first question of chapter 3:

Assume that you want to generate a table of multiples of any given number. Write a program that allows the user to enter the number and then generates the table, formatting it into 10 columns and 20 lines. Interaction with the program should look like this (only the first three lines are shown):

    Enter a number: 7
7     14     21     28     35     42     49     56     63     70
77     84     91     98    105    112    119    126    133    140
147    154    161    168    175    182    189    196    203    210


I've already uploaded the solutions on my github account -- if you want to see them.
