Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.

Question

100%

I got stuck in the boolean function. Not sure if my function protypes and calls are correct either.

Program is in c++

//
E#include <iostream>
#include <string>
===============
=====
#include <fstream>
using namespace std;
void getlogin (string id, string& pw);
bool validateLogin (string id, string pw);
void showResult();
Qint main()
{
string id;
string pw;
getlogin (id, pw);
validatelogin(id, pw);
showResult();
}
Evoid getlogin (string& id, string& pw)
{
cout << "Enter your ID: ";
getline(cin, id);
cout << "Enter your PW: ";
getline(cin, pw);
a bool validateLogin (string id, string pw)
{
bool result;
ifstream infile();
infile.open("login.txt");

HW_7a-1c
Write a program that prompts the user to enter an ID and Password. The ID and Password the user
enters are compared to the ID and Password in a file. If the user's ID and Password match the ones
on file, VALID should display on the screen. Otherwise, INVALID should display.
1. In your project, create a new text file named: login.txt
A File
Edit
View
Project
Build
3 -* 2-
Source.cpp
Enter an ID and Password, like this:
tommy
2 12345
2. Use these 3 functions in this program:
getLogin, validateLogin and showResult
3. In main(), declare 2 string variables: id and pw
4. In main(), call a function named: getLogin
A void function.
In the function, the user is prompted to enter an ID and Password (see output).
/* OUTPUT
Enter your ID : tommy
User is asked for an ID and PW in the getLogin function.
Enter your PW
12345
Valid.
Valid or Invalid is displayed in the showResult function.
* /
5. Then, in main(), call a function named: validateLogin
The function returns a bool value (true or false).
Pass the user's id and pw to the function.
In the function, open the login.txt file.
Read in the lID and PW in the file into two string variables declared in the function.
Name the two variables: filelD and filePW
Still in the function, compare the filelD and filePW to the id and pw that were passed
from main().
If they are the same, the function returns true. Otherwise, false is returned.
The bool value returned to main is assigned to a bool variable named: result
6. In main(), call a function named: showResult
Pass the bool variable, result, to the function.
If result
true, the function outputs: Valid
==
Otherwise, the function outputs: Invalid
