add more code given bellow program that means (( you can input a password and the output checking the password is valid or not and also the password is hard or weak)) the program,s output show....the given password is too strong or strong or weak and also check the password is valid
View 2 RepliesI am new to C++ and am stuck on a program. I've got to create a password check program that makes sure the password rules are followed. Below is the code and the rules i have typed in the comments at the beginning of the program. I have to use loops and cant use arrays for this.
#include <iostream>
#include <string>
#include <cctype>
using namespace std;
int main() {
//Prompt user to entered a password to be tested
cout << "Password must be at least 8 characters long." << endl;
[Code] .....
What if I want to let the user know the number of trials left...? Like "2 attempts left", "1 attempt left"?...

int main () {
ifstream file("test.txt");
string password;

I'm trying to write this c++ programe:
Write a password prompt that gives a user only a certain number of password entry attempts, so that the user cannot easily write a password cracker.
Using FOR Loop. I know this can be easily done using while loop. But I want to know how to do it with for loop aswell.
Here is what I have so far:
Code:
#include <iostream>
#include <string>
using namespace std;
int main ()
[Code] ....
I don't see where the problem is.. The program just executes and does nothing.
So I need to make a program that recieves a 10 letter only password, then once the password is entered, it starts off as AAAAAAAAAA...AAAAAAAAAB...AAAAAAAAAC...etc, Until it gets the correct password, which it then stops. This is for a science fair project on cyber security not for malicious purposes ...

I am trying to build a program that takes a user password (6+ characters, One uppercase, one lower case, and one number), and checks for errors. The idea is that if the user is doing something wrong (say, forgetting to use an uppercase letter), the program will tell them what the error is, and prompt them to enter the program again.
I get through the building process without errors, but whenever I run the program, I get this error: [URL] ....
Here is my code:
#include <iostream>
#include <cctype>
using namespace std;
bool checkPass(char [], int); //Password Checking Function
char convert(string);
[Code] ....
According to the box, the error appears on line 56 and 68.
Code:
#include<iostream.h>
#include<conio.h>
#include<string.h>
void main() {
clrscr();
int i=0,flag=1;
cout<<"Enter the password.";
[Code] ....
When I input the password, the Backspace and the Enter keys are not working as they should. Also, I want to know if I can press enter only once to input the password, not twice.
Compiler is Turbo C++ 3.0 on Windows 7.
I tried to build a basic username-password verification program; I already have 2 text documents, usr.txt and pass.txt in which username and password are stored. Then have written this program to check the username and password, but every time it says Access Denied.
Here's what I have written:
#include<stdio.h>
#include<conio.h>
void main()

I am trying to make a simple login program that reads username and password from a text file.
In my text file I have:
name1;pass1
name2;pass2
name3;pass3
name4;pass4
name5;pass5
Everything is working okay with name1 and pass1, but if I try to log in with different credentials, for example name2 and pass2 it says "invalid details"
Here is my code:
string user, chuser;
string pass, chpass;
string los;
ifstream loginData("logindata.txt");
cout << "Please type in your username:" << endl;
getline(cin, user);
[code].....
I'm trying to develop a deeper knowledge of how loops work (and what better way todo that than a dynamic password guesser). My main problem lies with the conflict between data types, as I try to point to a char at a specific index position of the password guess.
See in my code (at line 57):
Code:
#include <iostream>
#include <iterator>
#include <algorithm>
#include <string>
#include <cstdlib>
#include <iomanip>
using namespace std;
string AlphaNum("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789");//62 possible characters
int size = AlphaNum.length();//should be 62
[Code] ....
This is annoying, because strings are arrays of characters themselves.
I could not find the mistake in this program....
Code:
//cpp program to check whether a number is palindrome or not
#include<iostream.h>
#include<conio.h>
//the class
class palindrome
[Code] ....
I get this error..In function 'main':
p6.c.text+0x6a): undefined reference to 'palindromeness'
collect2: 1d returned 1 exit status
This is program is suppose to check if a phrase is a palindrome or not.I need to write a function definition for _Bool palindromeness(char str[])but I am having a tough time figuring that part out. I am brand new to programming..this is my first class and I am just learning arrays and pointers.
I'm writing a program to check whether codes from a file are invalid, valid, inactive, or valid and active, but can't get it to work properly. The invalid codes are being found, but the other three are not. I think it may have something to do with my "active" function.
#include <iostream>
#include <fstream>
#include <string>
#include <cctype>
using namespace std;
struct ActiveCodes {
string code;
bool flag;

Check the Leap Year Program In C++:

So I've been tasked with creating a program that checks to see whether or not a string is a palindrome. It has to remove whitespace, punctuation, and capitalization for obvious reasons. Getting some errors which I'm not sure how to correct.
On an unrelated note, while programming in the console, my cursor has turned into a gray box and replaces characters when typing, instead of pushing them forward, etc. How do I return it to normal?
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
bool isPalin(string& palin);
string cleanUp(string& palin);

Is there any opensource tool which can check the coding style use in a program.

Missing conditions to check for unbalanced parentheses Program doesn't catch left parentheses returns YesPairs wrong parentheses together, (} returns Yes, should be No Cases with incorrect output (}, (], ))), }}}, ]]], just a space or nothing entered. how I can correctly catch the cases I've missed
Code:

So I have to write a program that outputs a check with correct spacing and everything.
Create a project titled Lab7_Check. Write a program that asks the user the check information and prints the check. The dialog should be as follows:
date: 2/23/2010
name: William Schmidt
amount, dollars: 23
cents: 30
payee: Office Max
your check:
William Schmidt 10/13/2013
pay to: Office Max $23.30
twenty three and 30/100 dollars
You may assume that a person always has the first name and last name (no middle names or initials). The payee name is also always two words. The dollar and cent amount are integers and the amount is always less than 100 dollars. Note that the dollar amount could be zero, in which case, when you spell the dollar amount, it should print "zero". The date is always a single (non-white space separated string). Your date, dollar amount in numbers and the word "dollars" have to vertically align.
This is the code I have so far.
#include <iostream>
#include <string>
using namespace std;
int main(){
string date;
string firstname;
string lastname;
[Code] .....
How would I check for proper data type when someone is to input a value into the program? Ex:
int i;
string a;
cout << "Enter a number: ";
cin >> i;
cout >> "Enter a string: ";
cin >> a;
How would you check to make sure that int i would be an actual number and not a letter like "a"?
I wrote a program that should check if phrase is in file and output the result.
File:
//////////////

Ay Carumba!

Why my program doesn't cout?
#include <cstdlib>
#include <cstdio>
#include <iostream>
#include <fstream>
using namespace std;
string checkData (char Input[], char dataB [], int nMAX){
[Code] .....
For my c++ we're suppose to write a program that prints out a check. It's suppose to translate the numeric value of the dollars to worded strings.
Header File:
#ifndef CHECKWRITING_H
#define CHECKWRITING_H
#include <string>
[Code]....
I have written a program which uses a pid to check if the process is currently running and return a value based on the system call result.But the program core dumps
Code:
#include <stdio.h>
#include <string.h
int main( argc, argv )
int argc;
char * argv[];
{
int p_pid = 99;
char buff[1000];
}
[code]....
What is the mistake in this code and is it portable in both unix/linux , is the method secure (grepping for program name )?
How you can make a c++ program that checks to see if the user presses the power button on their computer? And if so, how?
