[C++] 4.17 LAB: Print string in reverse Write a program that takes in a line of text as input, and outputs that line of text in
Readme [11.4K]

The program illustrates the use of string manipulations.

String manipulation involves carrying out several operations (such as splitting and reversing of strings).

The program in C++ where comments are used to explain each line is as follows:

#include <bits/stdc++.h>

using namespace std;

int main(){

   //This declares a string variable

string str;

//This gets input for the variable

getline(cin, str);

//The following is repeated, until the user inputs <em>"Done", "done" or "d"</em>

while(str != "Done" && str !="done" && str !="d"){

    //This reverses the string

    reverse(str.begin(), str.end());

    //This prints the reversed string

    cout << str<<endl;

    //This gets another input

    getline(cin, str);

}  

return 0;

}

At the end of each loop, the reversed string is printed.

Create a java class for Bank Accounts with these public String attributes: ownerName, acctNbr and these private double attribute
Readme [11.4K]

Answer:

public class BankAccounts

 {

   public String ownerName;

   public String acctNbr;

   private double debits;

   private double credits;

   public BankAccounts(String ownerNm, String acNum)

  {

    debits = 0;

    credits = 0;

    ownerName = ownerNm;

    acctNbr = acNum;

  }

public void addDebit(double debitAmt)

  {

    if(credits > (debits + debitAmt))

      debits = debits + debitAmt;

    else

      System.out.println("Insufficient balance");

}

   public void addCredit(double creditAmt)

  {

    credits = credits + creditAmt;

  }

public double getBalance()

  {

    double balance = 0;

    if((credits - debits) > 0)   // return the value if there is actually some balance left.

      balance = credits - debits;

    return balance;   //returns 0 if credits are lesser or equal to debits

  }

 }

Explanation:

Here class name is <em>BankAccounts </em>which can be used to create a new bank account whenever any user wants to open a bank account. This class will help to track any new account opening, debits and credits operations carried out on that account.

We have a constructor here, which accepts 2 arguments i.e. Bank account <em>Owner Name</em> and <em>Account Number</em>. The constructor also sets the values of <em>debits </em>and <em>credits</em> as 0.

The methods <em>addDebit()</em>, <em>addCredit()</em> and <em>getBalance()</em> help to perform Debit and Credit operations on the account.

NOTE: The method <em>getBalance()</em> returns a positive value only when credits are greater than debits.

The method <em>addDebits()</em> can add debits only as the condition that the credits are greater than the resultant debits.

The code for class <em>BankAccounts</em> is hereby attached.
