Objectives
After this lab assignment, students should be able to:
Design modular programs based on specifications
Define and call functions with conditional logic
Write programs that use functions
●
●
Background
A bank uses the following flowchart to determine whether a customer is eligible for a loan. It
contains four steps, separated by color.
0
0
0

double
askAmount()

How much would you
like to borrow?
cin >> loan
if loan < 0
Please enter positive #
What is your yearly
Income?
cin >> income
if income < 0
Please enter positive #
askLoan()
Return type: bool
Parameter(s): None
askIncome)
Yes
Return type: double (loan)
Parameter(s): None
decideLoan()
Would you like to take
out a loan?

Thanks for visiting the bank!
Yes/Y/yes/y
or
No/N/no/n
No
Return type: double (income)
Parameter(s): None
askAmount()
0
0
if income <= 10,000
REJECT
if income > 10,000
and income < 100,000
Instructions:
You will use the flowchart to design and write a program that uses a function for
each step. Write a program named bankloan.cpp that defines and calls the
following functions, EXACTLY as specified below:
if income >= 100,000
ACCEPT
bool decideLoad(double income, double loan)
bool askLoan()
Return type: bool
Parameter(s): double (income), double (loan)
Invalid choice
Please enter yes or no
if income* 5 >= loan
ACCEPT
if income * 5 < loan
REJECT
When validating the user input for askLoan(),
Validate all user input using loops: accept the following user input for each choice:
"Yes", "Y", "yes", and "y" returns true
"No", "N", "no", and "n" returns false
When validating the user input for
askIncome and askAmount(), make sure the input is
greater than or equal to 0.

Sample Output 1
Would you like to take out a loan?
maybe
Invalid choice; please enter yes or no.
Would you like to take out a loan?
Yes
How much would you like to borrow?
45000
What is your yearly income?
15000
Congratulations! Your loan request for $45000 has been
Sample Output 2
Would you like to take out a loan?
y
How much would you like to borrow?
5000000
What is your yearly income?
45000
Sorry! Your loan request for $5000000 has been rejected.
Notes
You MUST properly define and call the four functions. Just because the program works, does
not mean it is properly written
You may NOT use any global variables in your program. You can, however, send arguments to
functions and use their return values

Expert Solution

Step 1

Algorithm:

1. Create a bool function called askLoan which will ask the user if they would like to take out a loan and return a boolean value.
2. Create a double function called askAmount which will ask the user how much they would like to borrow and return the value.
3. Create a double function called askIncome which will ask the user what their yearly income is and return the value.
4. Create a bool function called decideLoan which takes two double parameters, income and loan, and returns a boolean value.
5. In main, create a boolean variable called wantsLoan and assign it to the return value of askLoan.
6. If wantsLoan is false, print out an appropriate message and return 0.
7. Else, create a double variable called loan and assign it to the return value of askAmount.
8. Create a double variable called income and assign it to the return value of askIncome.
9. Create a boolean variable called isApproved and assign it to the return value of decideLoan.
10. If isApproved is true, print out an appropriate message.
11. Else, print out an appropriate message.
12. Return 0.
