Question

C++ Loops homework

Prompt the user for a desired password, input the password.

Your program may assume without checking that there is no input failure and that

the password contains no white space.

Let's say the rules for a legal password are:

# chars must be in [4, 8]

# digs must be >= 2

The password must contain at least one letter of each case

The password must contain at least one char that's not a letter or digit

An example run of your program might go as

What password do you want? Blah00!

good password

Another run might go as

What password do you want?: A.b8x

bogus password, you're probably a criminal

Prompt the user, input as many unsigneds as the user want to type.

When the user types a non-# or a 0, terminate the program.

For each positive # the user types, output all the (positive) factors of that number.

(As usual, disregard the possibility that the user will type a negative number or a

number with a fractional part.)

An example run of your program might go as

Type #'s, 0 or non-# to quit:

12

1 2 3 4 6 12

100

1 2 4 5 10 20 25 50 100

1

1

101

1 101

blah

thanks for the question, here is the 2 program in C++

===========================================================================================

#include<iostream>

using namespace std;

bool validatePassword(const string password){

               

                if(password.length()<4 || password.length()>8){

                                return false;

                }

                int lowerCaseCount=0, upperCaseCount=0, digitCount=0, nonAlphaNumericCount=0;

                for(int index=0;index<password.length();index++){

                                char letter = password.at(index);

                                if('0'<=letter && letter<='9')digitCount++;

                                else if('a'<=letter && letter<='z')lowerCaseCount++;

                                else if('A'<=letter && letter<='Z')upperCaseCount++;

                                else nonAlphaNumericCount++;

                }

                return digitCount>=2 && lowerCaseCount>=1 && upperCaseCount>=1 && nonAlphaNumericCount>=1;

               

}

int main(){

               

                string password;

                cout<<"Enter password: ";

                cin>>password;

                bool isValid = validatePassword(password);

                if(isValid){

                                cout<<"Good Password !";

                }else{

                                cout<<"Bogus Password, you're probably a criminal";

                }

}

#include<iostream>

using namespace std;

int main(){

               

                int number;

                cout<<"Type #'s, 0 or non-# to quit: ";

                while(true){

                                cin>>number;

                                if(cin.fail()){

                                                break;

                                }else if(number==0){

                                                break;

                                }

                                for(int factor=1;factor<=number;factor++)

                                if(number%factor==0)cout<<factor<<" ";

                                cout<<endl;

                }

}
