Question 4

Which statement is correct about a function prototype?

Group of answer choices

A function prototype is always optional.

A function prototype is only used in a header file.

A function prototype lets the compiler know what the return type and parameter types are for a function.

A function prototype is always placed after a call to the function.

Question 5

What is the term for using a function?

Group of answer choices

call

function

use

access

Question 6

Which statement is not true about using functions?

Group of answer choices

It allows code reuse.

It provides easier testing and debugging.

It breaks a large problem into smaller ones.

It doesn't let you break up your program into different files.

Question 7

For the function and function call shown below, which statement is true about the relationship between n1 and valueToConvert?

int n1;

int convertedValue = convert(n1);

int convert (int valueToConvert)

{

// function body is here

}

Group of answer choices

n1 and valueToConvert point to the exact same location in memory

n1 is a copy of valueToConvert

valueToConvert will have the same value as n1

valueToConvert has no relationship to n1

Answer 1

Q1.

Given prototype is
double coinTotal(double coinValue, int nCoins)

Return type is 'double'
Function takes 2 parameters, 'coinValue' and 'nCoins'
Name of the function is 'coinTotal'

Q2.

Arguments let the user know what data needs to be sent

Q3.

int convertedValue = convert(n1);

n1 is an 'argument' to the function

Q4.

A function prototype lets the compiler know what the return type and parameter types are for a function.

Q5.

Using is function is known as making a function 'call'
'call'

Q6.

It doesn't let you break up your program into different files.

We can spread multiple functions across different files

Q7.

int n1;

int convertedValue = convert(n1);

int convert (int valueToConvert)

{

// function body is here

}

When we make a function call, valueToConvert will have same value as n1

(c) valueToConvert will have the same value as n1
