Answer 4

1. PRE-DEFINED FUNCTIONS
2. USER DEFINED FUNCTIONS

Question 5

• ALREADY BEEN DEFINED AS A PART OF THE LANGUAGE

Answer 5

PRE-DEFINED FUNCTIONS

Question 6

• FUNCTIONS CREATED BY A USER.

Answer 6

USER DEFINED FUNCTIONS

Question 7

RETURN STATEMENT

Answer 7

CAUSES THE VALUE TO BE RETURNED TO THE CALLING FUNCTION.

Question 8

WHAT IS A VALUE RETURNING FUNCTION?

Value returning functions are used when only one result is returned and that result is used directly in an expression.

Question 9

a function declaration that does not include the body of the function.

Answer 9

FUNCTION PROTOTYPE

Question 10

FUNCTION DEFINITION

Answer 10

A FUNCTION DECLARATION THAT INCLUDES THE BODY OF THE FUNCTION. IT IS THE ACTUAL CODE OF THE FUNCTION AND ALWAYS OUTSIDE THE main( ) FUNCTION.

Question 11

IT IS USED WHEN INPUT/OUTPUT IS PERFORMED AND MORE THAN ONE VALUE IS TO BE RETURNED BY MODIFYING ONE OR MORE PARAMETERS RATHER THAN USING A RETURN STATEMENT.

Answer 11

VOID FUNCTION

Question 12

A VOID FUNCTION DOES NOT RETURN A VALUE TO ITS CALLER.

Answer 12

VOID FUNTION

Question 13

LOCAL VARIABLE

Answer 13

A variable declared within a block and not accessible outside of that block. When the function ends (returns) all of its local variables are destroyed.

Question 14

A variable declared outside of all the functions in a program.

Answer 14

GLOBAL VARIABLE

Question 15

When you send a parameter to a function and its value will NOT BE MODIFIED, use a value parameter. When the function is CHANGING the actual parameter, such as in an input function, use a reference parameter.

Answer 15

PARAMETERS

Question 16

A formal parameter that receives a copy of the contents of the corresponding argument (actual parameter) AND RETURNS A SINGLE VALUE.

Answer 16

VALUE PARAMETER

Question 17

A formal parameter that receives the address (location in memory) of the corresponding argument (actual parameter). A reference parameter is noted with an ampersand (&) following the data type of the formal parameter AND CAN RETURN A MULTIPLE VALUES.
IT ALLOWS THE CALLED FUNCTION TO DIRECTLY ALTER THE VARIABLES VALUE.

Answer 17

REFERENCE PARAMETER

Question 18

RECURSION

Answer 18

The process in which a function calls itself is known as recursion and the corresponding function is called the recursive function.
