Question

C++

Using what you know about inputs and outputs, code a simple ATM interaction. Your ATM will start with only $500 to give out, and YOUR balance will be 1000. The amounts the ATM can dispense are $40, $80, $200 and $400. After you've received your disbursement, the console will show the amount you have left in your account, as well as how much the ATM has to dispense (we live in a small, fictional town - no one will use this information for nefarious purposes).

You may choose to use characters to show the interface, or just list the options for the user at the console.

Save the following code in file atm.cpp .compile and run it.

#include <iostream>
using namespace std;

int main(){
int choice = 0;
int balance = 1000;
int withdrawal = 0;
int max_withdraw = 500;
int step_withdraw = 0;
cout<<"\nInitial Balance = "<<balance;
while(balance > 0 && withdrawal <= max_withdraw) {
//The choice Menu to ATM user
cout<<"\n>>>>>>>>>>>>>>>>>>>>>>>>>" << endl;
cout<< "Choose One" << endl;
cout<<"1. $40 "<< endl;
cout<<"2. $80 "<< endl;
cout<<"3. $200 "<< endl;
cout<<"4. $400 "<< endl;
cout<<"5. EXIT "<< endl;
cout<<">>>>>>>>>>>>>>>>>>>>>>>>>" << endl;
  
cout<<"\nEnter your choice( 1 - 5): ";
  
cin>>choice;
// Take action as per choice...
switch(choice){
    case 1:
        step_withdraw = 40;
        break;
    case 2:
        step_withdraw = 80;
        break;
    case 3:
        step_withdraw = 200;
        break;
    case 4:
        step_withdraw = 400;
        break;
    case 5: exit(0);
default: cout<<"\nInvalid choice";
break;
}
// Maintain ATM balance
if(withdrawal + step_withdraw > max_withdraw){
cout<<"\nYou can't withdraw more than " << max_withdraw << endl;
exit(0);
}else{
balance = balance - step_withdraw;
withdrawal = withdrawal + step_withdraw;
cout <<"\nYour Balance = " << balance;
cout <<"\nYour total withdrawal = " << withdrawal;
}
}
return 0;
}

Here is the program output:

Initial Balance = 1000
>>>>>>>>>>>>>>>>>>>>>>>>>
Choose One
1. $40
2. $80
3. $200
4. $400
5. EXIT
>>>>>>>>>>>>>>>>>>>>>>>>>

Enter your choice( 1 - 5): 4

Your Balance = 600
Your total withdrawal = 400
>>>>>>>>>>>>>>>>>>>>>>>>>
Choose One
1. $40
2. $80
3. $200
4. $400
5. EXIT
>>>>>>>>>>>>>>>>>>>>>>>>>

Enter your choice( 1 - 5): 2

Your Balance = 520
Your total withdrawal = 480
>>>>>>>>>>>>>>>>>>>>>>>>>
Choose One
1. $40
2. $80
3. $200
4. $400
5. EXIT
>>>>>>>>>>>>>>>>>>>>>>>>>

Enter your choice( 1 - 5): 1

You can't withdraw more than 500
