QUIZ 4: Derived Data Types (Functions, Arrays, Pointers, References)

Data types that are derived from primitive data types are called:

Derived Data Types (from primitives)

A block of code or program-segment defined to perform a specific well-defined task is called a:

Function (block of code)

The syntax for a function is:

FunctionType FunctionName(parameters) (function syntax)

A collection of items stored at continuous memory locations is called an:

Array

The syntax for declaring an array is:

DataType ArrayName[size_of_array] (array syntax)

A pointer is a symbolic representation of addresses that enables programs to:

Simulate call-by-reference and create/manipulate dynamic data structures

The syntax for declaring a pointer is:

dataType *var_name; (pointer with asterisk)

A reference is an:

Alternative name for an existing variable

The syntax for declaring a reference is:

dataType& ref = <variable>

Symbols that denote calculation, relationship, comparison, and operations on operands are called:

Operators

The increment operator ++ increases the value of a variable by:

1

The decrement operator -- decreases the value of a variable by:

1

In y = ++x;, what happens to the value of x?

x is incremented before the assignment to y

In y = x++;, what happens to the value of x?

x is incremented before the assignment to y

In y = x++;, what happens to the value of x?

x is incremented after the assignment to y

With x = 5; y = ++x;, what are the values of x and y?

x = 6, y = 6

With x = 5; y = x++;, what are the values of x and y?

x = 6, y = 5

Which operator is used to check if two operands are equal?

==

Which operator checks if two operands are NOT equal?

!=

Which logical operator returns True only if both operands are true?

&&

Which logical operator returns True if either of the operands is true?

||

Which logical operator returns True if the operand is false?

!

What is the assignment operator in C++?

=

What does x += y do?

x = x + y

Which bitwise operator performs Bitwise AND on operands?

&

Which bitwise operator performs Bitwise OR on operands?
