Explanation / Answer

1. A function is a defined and a variable is a declared

2. You don't have to keep passing variables between functions.
   - A globally declared variable is available to all the functions for use.

3. F5 for start debugging and Shift-F5 for stop debugging  
   refer https://msdn.microsoft.com/en-in/library/8b59xk0f%28v=vs.90%29.aspx

4. All the above

5. A loop that falls within the body of another is a nested loop.

6. it executes 10 times

7. setprecision(2)

8. The output will be :
"You got five apples!"
The end of the program is reached.

9. case statements are checked sequentially, but the order of cases doesn't matter.

10. The answer is 3.75.
   It can be re-written as (3.0/4.0) + 3 + (2/5) = (0.75) + 3 + (0)
   notice that (3.0/4.0) are both represented as floating, so the result will also be floatin value. But in case of (2/5), both are integers, so the fractional part will be truncated and the result will be zero (an int).

11. endl is found in std namespace

12. It starts with an open curly bracket, {

   int main()
   {
       // code
   }

13. Comments are represented by // and /* */

14. IDE stands for Integrated Development Environment

15. C++ is FUN
