Chapter 6 Review: Functions
prototype
A ____ eliminates the need to place a function definition before all calls to the function.
local
A ____ variable is defined inside a function and is not accessible outside the function.
prototype, definition
Either a function's ___ or its ___ must precede all calls to the function.
void
If a function doesn't return a value, the word ___ will appear as its return type
local
If a function has a local variable with the same name as a global variable, only the ____ variable can be seen by the function.
&
Reference variables are defined like regular variables, except there is a ____ in front of the name
parameters
Special variables that hold copies of function arguments are called ____
false
T/F: All static variables are initialized to -1 by default
true
T/F: Arguments are passed to the function parameters in the order they appear in the function call
false
T/F: Changes to a function parameter always affect the original argument as well
false
T/F: Function headers are terminated with a semicolon
true
T/F: Function prototypes are terminated with a semicolon
true
T/F: Functions should be given names that reflect their purpose
true
T/F: If other functions are defined before main, the program still starts executing at function main
true
T/F: In a function prototype, the names of the parameter variables may be left out
true
T/F: Initialization of static local variables happens only once
true
T/F: Many functions may have local variables with the same name
true
T/F: Overuse of global variables can lead to problems
true
T/F: Static local variables are not destroyed when a function returns
false
T/F: The exit function may only be called from main
false
T/F: When a function terminates, it always branches back to main, regardless of where it was called from
false
T/F: it is not possible for a function to have some parameters with default arguments and some without
true
T/F: the scope of a parameter is limited to the function which uses it
exit
The ____ function causes a program to terminate
function
The ____ is the part of a function definition that shows the function name, return type and parameter list.
constant
The value of a default argument must be a ____
parameters
Two or more functions may have the same name, as long as their ____ are different
zero
Unless you explicitly initialize global variables, they are automatically initialized to ____
arguements
Values that are sent into a function are called ____
last
When a function uses a mixture of parameters with and without default arguments, the parameters with default arguments must be defined ____
value
When only a copy of an argument is passed to a function, it is said to be passed by ____
reference
When used as parameters, ____ variables allow a function to access the parameters of the original argument
default
____ arguments are passed to parameters automatically if no argument is provided in the function call.
static
____ local variables retain their value between function calls
return
____ statement causes a function to end immediately
global
____ variables are defined outside all functions and are accessible to any function within their scope
global
____ variables provide an easy way to share large amounts of data among all the functions in a program
reference
reference variables allow arguments to be passed by ____
