In passing an array as a parameter to a function that processes it, it is often necessary to pass a parameter that hold the __________ of __________ used in the array.

number, elements

__________ functions are functions that have the same name but a different parameter list.

overloaded

Arrays used as arguments are always passed by __________.

pointer

The name of an array, without any brackets, acts as a(n) __________ to the starting address of the array.

pointer or reference

Functions that do not return a value are often called _________ in other programming languages.

procedures

Default arguments are usually defined in the __________ of the function.

prototype

A function returning a value should never use pass by __________ parameters.

reference

Default values are generally not given for pass by __________ parameters.

reference

Parameters that are passed by __________ are similar to a pointer variable in that they can contain the address of another variable. They are used as parameters of a procedure (void function) whenever we want a procedure to change the value of the argument.

reference

Pass by __________ indicates that the location of an actual parameter, rather than just a copy of its value, is passed to the called function.

reference

return

__________ refers to the region of a program where a variable is "active."

scope

The vector data type is a(n) __________ container.

sequence

Variables of a function that retain their value over multiple calls to the functions are called _________ variables.

static

A(n) __________ is a dummy of function that just indicates that a function was called properly.

stub

Pass by __________ indicates that a copy of the actual parameter is placed in the memory of location of its corresponding formal parameter.

value

void

In cin.getLine(name, 25) the 25 indicates that the user can input at most __________ characters into 'name'.

&

The __________ symbol means "address of."

&

The __________ symbol is the dereferencing operator.
