•PA 4 – Password Game
Please write a C++ program to check a password to see whether it is really secure.This program is like a password game.If the password is not secure, your program must report all its security violations.Please see the following test case #1 to design your application program.You must stop your program when the password from the user is quit.In other words, “quit” cannot be a password in this game.

You must write 7 functions to check the following 7 security rules for any given password.
Rule 1: Length invalid – The length of the password must be 8 to 12 only.
Rule 2: No Space – The password must not contain any space or blank character.
Rule 3: At least 2 digits – The password must contain at least 2 digits.
Rule 4: At least 1 upper-case letter – The password must contain at least one upper-case letter.
Rule 5: At least 1 lower-case letter – The password must contain at least one lower-case letter.
Rule 6: At least 1 special character – The password must contain at least one special character, which can be one of the following 7 choices: ‘$’, ‘#’, ‘@’, ‘&’, ‘*’, ‘?’, or ‘!’.
Rule 7: No special numbers – The password must not contain any of the following 4 numbers: 2019, 2018, 2017, or 2016.

The following is a sample standard test, which must be your test case #1.You must also do test case #2 and test case #3 with different set of input data.Each test case must test at least 5 passwords with 2 secure and 3 non-secure. All those 7 violations must appear in those 3 non-secure passwords.

Welcome to the PASSWORD game designed by Dr. Simon Lin!
Please enter a password:0 0 7
The password “0 0 7” violates the following rule(s):
Rule 1: Length invalid – The length of the password must be 8 to 12 only.
Rule 2: No Space – The password must not contain any space or blank character.
Rule 4: At least 1 upper-case letter – The password must contain at least one upper-case letter.
Rule 5: At least 1 lower-case letter – The password must contain at least one lower-case letter.
Rule 6: At least 1 special character – The password must contain at least one special character, which can be one of the following 7 choices: ‘$’, ‘#’, ‘@’, ‘&’, ‘*’, ‘?’, or ‘!’.
Please enter a password:$007SLin!
Your password “$007SLin!” is very secure! Congratulations!
Please enter a password:#1SimonLin
The password “#1SimonLin” violates the following rule(s):
Rule 3: At least 2 digits – The password must contain at least 2 digits.
Please enter a password:SLin2019@
The password “SLin2016@” violates the following rule(s):
Rule 7: No special numbers – The password must not contain any of the following 4 numbers: 2019, 2018, 2017, or 2016.
Please enter a password:$2020LinWins
Your password “$2020LinWins” is very secure! Congratulations!
Please enter a password:quit
Your password “quit” is to quit the game.
Thank you for playing the PASSWORD game designed by Dr. Simon Lin!

•==========================================================================.
•The following is a sample code with some pseudo-code for this Password Game program:
#include “pch.h”
#include // for string input
#include // Access input output stream
using namespace std;// Access cout, endl, cin
string pw; // global pw for the password
bool r1, r2, r3, r4, r5, r6, r7; // global 7 boolean flags for violations
void s1(); void s2(); void s3(); void s4();
void s5(); void s6(); void s7();// 7 prototypes

int main()
{ // begin of main
cout << “Welcome to the PASSWORD game designed by Dr. Simon Lin!” << endl;cout << “Please enter a password:” << endl;getline(cin, pw); // pw may have blanks anywherecout << “Your password “” << pw << “” ” ;while (pw != “quit”){ //begin of while loops1(); s2(); s3(); s4();s5(); s6(); s7();// call to check all 7 rules for satisfactionif (r1 && r2 && r3 && r4 && r5 && r6 && r7) // all 7 rules satisfied cout << “is very secure! Congratulations!” << endl ;else // insecure password{ // print the insecure password message with all rules violated cout << “violates the following rule(s):” << endl ;if (!r1) cout << “Rule 1: Length invalid – The length of the password must —if (!r2) cout << “Rule 2: No Space – The password must not contain any space —if (!r3) cout << “Rule 3: At least 2 digits – The password must — if (!r4) cout << “Rule 4: At least 1 upper-case letter – The password must —if (!r5) cout << “Rule 5: At least 1 lower-case letter – The password must —if (!r6) cout << “Rule 6: At least 1 special character – The password must –if (!r7) cout << “Rule 7: No special numbers – The password must not contain — } // print all the violated rules in detailcout << “Please enter a password:” << endl;getline(cin, pw); // pw may have blanks anywherecout << “Your password “” << pw << “” “;} // end of while loopcout << “is to quit the game.” << endl;cout << “Thank you for playing the PASSWORD game designed by Dr. Simon Lin!”;return 0 ; // normally done now} // end of main =======================================================You may use the following idea to check upper/lower case characters and digits string upperChars = “ABCDEFGHIJKLMNOPQRSTUVWXYZ”;string lowerChars = “abcdefghijklmnopqrstuvwxyz”;string specialChars = “$#@&*?!”;Some other helpful programming techniques/methods/functions for strings are as follows:(pw.find(“2019″) == string::npos)will return true if pw does not contain 2019. (pw.find(” “) == string::npos)will return true if pw does not contain any blank character.pw.length( ) will return the length of the string pw. You may need to use some string methods such as at( ), length( ), or find( ). A special technique to check for the Rule 3 (at least 2 digits in password) is as follows: void s3() // to check for security rule 3{ // begin of s3( )char c ;int countDigits ;string digits = “0123456789”;countDigits = 0;r3 = false;for (int i = 0; i < pw.length(); i++){c = pw.at(i);if (digits.find(c) != string::npos)countDigits++;}if (countDigits >= 2)
r3 = true; // for Rule 3 checking: at least 2 digits
} // end of s3( )

•How to submit your Lab or Project Assignment (PA)?
•(1) Each program must be well documented with block comments and proper line comments.
• The beginning of each program must have a block comment to show its author, date, and purpose.
• The following is an example of block comments:
// Author:You must use your full name here!
// Date: You must put today’s date here!
// Purpose: . . . You must show the purpose of this program here!
•(2) You must submit to Canvas the following 2 items as attachments:
• (a) Your source program (for example, CS243-PA4.cpp ), and
• (b) Your WORD document (for example, CS243-PA4-report .docx ) containing the listing of
• your C++ program, and the output of 3 test runs of your program (as shown below).
