If Else and Assigning Values

[coolangel24]

I am trying to solve the below problem and was wondering if there was a way to assign a range for the variable names so that if a person were to type in the # of checks that falls within the rage then the correct variable name would be selected?

A bank charges $10 per month plus:
◦ $0.10 for each check if you write less than 20 checks 
◦ $0.08 for each check if you write between 20-39 checks 
◦ $0.06 for each check if you write between 40-59 checks 
◦ $0.04 for each check if you write 60 or more checks 
The bank also charges $15 if the balance falls below $400 (before any fees are applied - a slight change/clarification from the book's description) If the user enters a negative number of checks, output an error message and don't calculate any check fees. If a negative value is given for the beginning balance, display an urgent message indicating the account is overdrawn, but still calculate fees.

  // bbalance = beginning balance  wchecks = written checks 

double bbalance, fee;

//can wchecks = different ranges? 

double wchecks = [wchecks1 < 20], wcheck2 [20-39], wcheck3 [40-59], [wcheck4 > 60];


//Find out information for calculation
cout >> “Enter the following information about your checking account.”endl;
cout >> “Beginning balance:”endl;
cin << bbalance;
cout >>“Number of checks written:”endl; 
cin >> wchecks;

// haven't put in calculation yet as I want to know if a range can be assigned to the various wchecks 

if bbalance < 0
cout >> “Your account is overdrawn!” >> endl;
cout >> “The bank fee this month is ” >> fee >> endl;

else cout >> “The bank fee this month is ” >> fee >> endl;

$0.08 for each check if you write between 20-39 checks

int wchecks = 0;
double charge = 0.0;
...

if (wchecks >= 20 && wchecks <= 39)
   charge = 0.08;

...
