Facing difficulty in answering second question of chapter 4 about cplusplus-prog-exercises HOT 3 CLOSED

Update 1: I have created a branch 'prog-ex-4.2-solution' to track the progress and the current status of this answer.

I have add the initial template of the answer, in the meantime, as a stub.

from cplusplus-prog-exercises.

TO-DO LIST

• Define a readMatrix() function to read a matrix of size m x n from the keyboard. (Completed in Update 2)
• Define a displayMatrix() function to display the matrix on the screen. (Completed in Update 2)

NOTE: I did a bit of digging into the issue that was preventing me to complete this issue... There are 2 ways for me to approach this problem:

1. By considering 2D array as static where m and n are known at compile time which will make the solution very simple and easy... This would more likely be my course of action, if I find the second approach difficult to implement.

2. By considering 2D array as dynamic where m and n will be given by the user at runtime.. This approach will be a bit more difficult since it uses pointers and concepts of dynamic memory allocation are applied...

In fact, I believe that the first approach is slightly more beginner-friendly but I realised that if I could implement the second approach, at this stage, then, the fear of pointers (which prevents a lot of beginner level learners to continue learning C++) might not be able to grip you (like it did me)..

Pointers and memory management are indeed difficult concepts to master and get comfortable in but these are important hurdles for anyone to overcome, if they need to learn C++ in the true sense..

Update 2: I have completed the answer of this question using the second approach as I mentioned in my TO-DO LIST.

Task(s) Completed:

• Define a readMatrix() function to read a matrix of size m x n from the keyboard.
• Define a displayMatrix() function to display the matrix on the screen.

Hence, this issue is now closed.

P.S: Branch 'prog-ex-4.2-solution' will be deleted after its merged with its base branch.
