 4. 
In most programming languages, the names of processing items can contain letters, numbers, underscores, punctuation characters or spaces.
 

 5. 
Most C++ programmers use uppercase letters for variable names.
 

 6.

 8. 
The standard output stream is called cout.
 

 9.

 11. 
The statement cout << "Enter current weekly pay: "; prompts the user to enter the current weekly pay.
 

 12. 
You should perform several desk-checks, using different data, to make sure that the program is correct.
 

 13. 
Errors in a program are called hacks.
 

 14.

 18. 
The file containing the source code is called the source file.
 

 19. 
Machine code is usually called assembly code.
 

 20. 
Many C++ systems, such as Microsoft Visual C++ and Borland C++ Builder, contain both the editor and compiler in one integrated environment, referred to as a GUI.
 

 21. 
A comment is a message to the person reading the program and is referred to as internal documentation.
 

 22. 
The C++ compiler processes the comments when it translates the source code into object code.
 

 23. 
Comments are statements in C++.
 

 24. 
Some functions return a value after completing their assigned task, while others, referred to as null functions, do not.
 

 25. 
A function header marks the beginning of a function.
 

 26. 
A program can contain multiple main() functions.
