Answer:
1. You can get a C++ program running by building an executable within an integrated development environment (IDE).
2. Yes, C++ is case sensitive. If a developer was naming their variable fooBar compared to foobar, it will recognize each variable differently. This is important because if you define fooBar in the global scope and foobar within a function then it won't generate a conflict; however, when working in a team this could have catastrophic consequences.
3. You can include libraries at the top of your header. A sample include like below.
#include <iostream>
#include <math.h>
The math.h means that it is a header file compared to a standard library.
A sample of how to call a library function could be like:
cin >> fooBar;
or
cout << fooBar;
This would accept keyboard input from the user and then it would show it back to the user afterwards.
