Exam 6: User-Defined Functions

A function ____________________ is a function that is not fully coded.

The output of the statement: cout << pow(3.0, 2.0) + 5 << endl; is ____.

A(n) ____________________ parameter s a formal parameter that receives a copy of the content of the corresponding actual parameter.

If a formal parameter is a nonconstant reference parameter, during a function call, its corresponding actual parameter must be a(n) ____________________.

Using functions greatly enhances a program's readability because it reduces the complexity of the function main.

Stream variables (for example, ifstream and ofstream) should be passed by ____________________ to a function.

The ____________________ of a function consists of the function name and its formal parameter list.

Which statement below about prototypes and headers is true?

In C++, a function prototype is the function heading without the body of the function.

Given the following function: int strange(int x, int y) { if (x > y) $\quad$ return x + y; else $\quad$ return x - y; } What is the output of the following statement? cout << strange(4, 5) << endl;
