Exercise 9-4: Writing Functions that Return Value

In this exercise, you use what you have learned about writing functions that return a value to answer Questions 1–2.

1.

Given the following variable declarations and function calls, write the function’s header:

a.Dim Price As Double Dim Percent As Double Dim NewPrice As Double NewPrice = calculateNewPrice(Price, Percent)_____________________________________________________________________________

b.Dim Area As Double Dim OneLength As Double Dim TwoLength As Double Area = calcArea(OneLength, TwoLength) _____________________________________________________________________________

c.Dim LowerCase As String Dim UpperCase As String UpperCase = changeCase(LowerCase)_____________________________________________________________________________

2.

Given the following function headers, write a function call:

a.Function findItem(ByVal ItemNumber _                        As Integer) As String_____________________________________________________________________________

b.Function cubed(ByVal Num1 As Integer, _                    ByVal Num2 As Integer) As Integer_____________________________________________________________________________

c.Function power(ByVal Num As Integer, _                    ByVal Exp As Integer) As Integer_____________________________________________________________________________

Explanation / Answer

Answer `1)

a)double dim_price;

double dim_percent;

double new_price;

new_price=calculate_newprice(dim_price,dim_percent); /* function call to calculate_newprice method */

Function Header: double calculate_newprice( double dim_price, double dim_percent);

b)

double dim_area;

double dim_onelength;

double dim_twolength;

dim_area=calcArea(dim_onelength,dim_twolength) ; /* function call to the method */

Function Header: double calcArea(double dim_onelength,double dim_twolength);

c)

String dim_lowercase;

String dim_uppercase;

uppercase=changeCase(dim_lowercase); ->function call

Function Header: double changeCase(double dim_lowercase);

Answer 2) The following are the function calls:

a)findItem(itemNumber);

b)cubed(num1,num2);

c)power(Num,Exp);
