GCSE Computer Science- 2.2 Programming Techniques

In an assignment operation,what appears on the right hand side

• Multiple variables that are destinations for data
• The assignment operator
• Source variables or operations
• Label for a variable that is destination of data

which of the following is not a valid constant

• UserName
• SPACE
• PI
• WORDLIMIT

Which of the following is a valid keyword for output?

• DISPLAY
• SHOW
• INPUT
• PRINT

Consider the following expression: a=b. This means

• The value of memory location b gets copied into memory location a
• The value of memory location a gets copied into memory location b
• b is being renamed into a
• a will always be equal to b

Quotation marks around a variable’s identifier imply

• It is a Boolean
• It is a real
• It is an integer
• It is a string

This variable type can only have True or False values

• Real
• Character
• Boolean
• Integer

The operator used to find if a number is wholly divisible by another number {returns 0 if true}:

• Division
• MOD
• Subtraction
• Integer division

The statement A OR B implies A and B are

• Strings
• Characters
• Booleans
• Integers

The following data types are used in selection conditions and while loops

• String
• Integer
• Boolean
• Character

Which of these is NOT an advantage of parameter passing

• Can cut down on the use of wasteful global variables
• Parameter passing makes it easier to use global variables
• More flexible coding
• The same subprogram can be reused in more cases
