Q&A
Quiz
Q How many levels deep can I nest if statements?
A There’s no limit. There is, however, a practical limit. If you have too many nested
if statements it gets very hard to keep all those brackets straight!
Q Will loops automatically terminate if something goes wrong?
A No. If you accidentally write an endless loop, that loop will continue to run until
you do something to stop it. You can stop a program stuck in an endless loop by
bringing up the Windows Task Manager (or the Close Program box) and ending
the errant task. If you executed the program via the C++Builder IDE, you can
choose Run | Reset Program from the main menu to kill the program.
Q Does a switch statement have to include a default section?
A No. The default section is optional.
Q Can I have more than one variable with the same name?
A Yes, provided they are in different scopes. You cannot have two variables named x
that are both declared within a code block. You can, however, have a global
variable named x and a local variable with the same name.
Q Can I use a structure by itself, without an object?
A No. Before you can use a structure you have to create an instance of the structure
and access the structure through the instance variable.
1. What statements are executed in the event that an if expression evaluates to true?

4. What do the break and continue statements do?
5. What is a global variable?
6. Can a structure contain a mixture of data types (char, int, long, and so on)?
