Question

Write a program to simulate a bank transaction. There are two bank accounts: checking and savings. First, ask for the initial balances of the bank accounts; reject negative balances. Then ask for the transactions; options are deposit, withdrawal, and transfer. Then ask for the account; options are checking and savings. Then ask for the amount; reject transactions that overdraw an account. At the end, print the balances of both accounts. in if and else statments only in c++

Answer 1

c++ code

#include <iostream>


using namespace std;
int main() {
        double checking_balance,saving_balance,amount;
        int transaction_option,account_type;
        cout<<"bank transaction window\n\n";
        cout<<"initial balance of the bank account(checking) :";
        cin>>checking_balance;
        if(checking_balance<0)  // when user enter -ve balance
        {
                cout<<"-ve balance not accepted";
                return main();
        }

                {

                checking_balance=checking_balance-amount;
                
                }

                checking_balance=checking_balance+amount;
                saving_balance=saving_balance-amount;

                else

        }
        cout<<"checking account balance = "<<checking_balance<<endl; //printing balance
        cout<<"saving account balance   = "<<saving_balance;

}

output 1 -deposit

output 2 - withdrawal

output3 - transaction
