Question

Please help me with the code. Thank you!

Description

James Vond has delivered us some intel that the enemy perpetrators have been tricked into going to a bank that we've wired and booby-trapped. However, we have not gotten a bank system in place and you are the only person who is capable of handling such a task. We need this plan to go off without a hitch because the money we'll be receiving will give us insight on the hideout's whereabouts. We are counting on you.

Signed, M

Objective

You will design a functioning bank system that will have functions that allows a user to withdraw, deposit, and check to see how much money is currently in their account. A main menu has already been created, so all that's left is for you to implement the functions.

Requirements

• You're required to implement 3 functions.
  • Withdraw Function: Takes in a float datatype as the parameter, prints the amount they withdrew, updates their existing bank balance, and prints their existing bank balance.
    • If the user decides to withdraw more money than their current account balance, print the amount of whatever is left in their account, update their existing balance to $0, and print out their existing balance.
  • Deposit Function: Takes in a float datatype as the parameter, prints out how much they deposited, updates their existing bank balance, and prints their existing bank balance.
  • Balance Function: Prints their existing bank balance.
• If negative numbers are used to deposit or withdraw, your program should output

Sorry, negative amounts are prohibited.

Other Helpful Information

• Only money amounts up to two decimal places will be used.
  • Acceptable: 100
  • Acceptable: 100.9
  • Acceptable: 100.99
  • Not acceptable: 100.999
• There are five test cases with non-hidden outputs. You have unlimited tries. Test to see what your output needs to look like in order to receive maximum credit

#include <iostream>
#include <iomanip>
using namespace std;

static float balance = 3647.72;

/*datatype*/ withdraw(/*parameter*/){

      //implement your code here

}

/*datatype*/ deposit(/*parameter*/){

      //implement your code here

}

/*datatype*/ checkBal(){

      //implement your code here
    
}

int main() {
   int choice;
   do{
      cout << "---------------------------------\n\tMAIN MENU\n---------------------------------\n";
      cout << "\n1) Withdraw Money";
      cout << "\n2) Deposit Money";
      cout << "\n3) Check Balance";
      cout << "\n4) Exit";
      cout << "\nPlease enter your desired number: \n";
      cin >> choice;
    
      switch(choice){
         case 1:
            cout << "Enter the amount: $\n";
            //some code & function call here
            break;
         case 2:
            cout << "Enter the amount: $\n";
            //some code & function call here
            break;
         case 3:
            //function call here
            break;
         case 4:
            cout << "Good-bye.";
            break;
      }
   }while(choice!=4);

   return 0;
}

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

#include <iostream>

#include <iomanip>

using namespace std;

static float balance = 3647.72;

//method to withdraw money

void withdraw(float amount){

              //validating amount

              if(amount<0){

                           //negative

                           cout<<"Sorry, negative amounts are prohibited."<<endl;

              }else{

                           //checking if amount exceeds balance

                           if(amount>balance){

                                         //displaying a message

                                         cout<<"Amount is greater than balance, withdrawing available amount"<<endl;

                                         //setting amount to whatever left in balance

                                         amount=balance;

                           }

                           //subtracting amount from balance

                           balance-=amount;

                           //displaying amount withdrawn and new balance

                           cout<<"$"<<amount<<" has been withdrawn"<<endl;

                           cout<<"You have $"<<balance<<" left in your account."<<endl;

              }

}

//method to deposit amount to balance

void deposit(float amount){

              //validating amount

              if(amount<0){

                           //negative

                           cout<<"Sorry, negative amounts are prohibited."<<endl;

              }else{

                           //updating balance,

                           balance+=amount;

                           //displaying deposited amount and printing new balance

                           cout<<"$"<<amount<<" has been deposited"<<endl;

                           cout<<"You have $"<<balance<<" left in your account."<<endl;

              }

}

//method to print balance

void checkBal(){

              //displaying balance amount

              cout<<"Your balance is $"<<balance<<endl;

}

int main() {

              //setting a fixed precision of 2 digits after decimal point

              cout<<setprecision(2)<<fixed;

              int choice;

              float amt;

              do{

      cout << "---------------------------------\n\tMAIN MENU\n---------------------------------\n";

      cout << "\n1) Withdraw Money";

      cout << "\n2) Deposit Money";

      cout << "\n3) Check Balance";

      cout << "\n4) Exit";

      cout << "\nPlease enter your desired number: \n";

      cin >> choice;

   

      switch(choice){

         case 1:

            cout << "Enter the amount: $\n";

            //getting amount and withdrawing

                                         cin>>amt;

            withdraw(amt);

            break;

         case 2:

              //getting amount and depositing

            cout << "Enter the amount: $\n";

            cin>>amt;

            deposit(amt);

            break;

         case 3:

              //checking balance

              checkBal();

            break;

         case 4:

            cout << "Good-bye.";

            break;

      }

   }while(choice!=4);

   return 0;
