C++ :: Create Password Check Program That Makes Sure That Rules Are Followed
Feb 27, 2014
I 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;
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
For now I've done a function that creates menus and prints them, and a function that creates the character as an object.
Now I want to be able to show the stats of the player on the main menu, the problem is that I don't know how to make a copy of the map as it's private...
"How to create login id and password" because i have to submit this assignment next weeks i dont know how to using passing by value or reference corectly/
For the Ouput its say this :
1>ClCompile: 1> GILA DAH!!.cpp 1>d:computer programmin ditg 1113jiwa ku sakitjiwa ku sakitGILA DAH!!.cpp(21): error C2664: 'strlen' : cannot convert parameter 1 from 'char' to 'const char *' 1> Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast 1> 1>Build FAILED.
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.
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.
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);
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.
Where are the c programming variable name rules defined? I usually use these two websites for figuring out these kind of things but I don't see it anywhere.
std::string str = "Hello"; std::string phrase = "Hello world"; std::string slang = "Hiya"; and i have these two rules to compare 2 strings object :
if two strings have different lenghts and if every character in the shorter string is equal to the corresponding character of the longer string, than the shorter string is less than the longer string.
if any characters at corresponding positions of two strings differ, then the result of the string comparison is the result of comparing the first character at wich the strings differ then my book says : if we apply the rules of the comparison we know that phrase is greater than str( ok i've understood this ) and that slang is greater than both slang and phrase ( why ?)
explain me rule number two ? in phrase and slang the characters differ and the first character that differ is not H so why my book says slang is bigger than phrase ?
I have been given an assignment that has to do with permutations. I am suppose to read a text file that contains the permutation rules and the text to be "permutated", and then output the rules and the new text into an output file.
So far, I've gotten this:
Code: # include <stdio.h> void printArray(FILE* file, char* array, int maxSize) { int i; for (i = 0; i<maxSize; i++) fprintf(file, "%c", *(array + i));
[Code] ....
Here is what the input file looks like:
Code: 0 1 2 3 4 5 6 7 8 9 4 5 6 0 9 7 8 1 2 3
Moderation in temper, is always a virtue; but moderation in principle, is a species of vice.
Here is what the output file is suppose to look like:
Code: 0 1 2 3 4 5 6 7 8 9 4 5 6 0 9 7 8 1 2 3
ratMnioodetem rpein al,ywa isvirsetu a t m;eod buon r inaticipp,lerina s cpeis of icvies - Temho. -ainaPes
The first two lines are the permutation rules. Currently I have figured out how to read the file into an array and then print it back out into a text.
What I want to do is figure out how to read only the first two line of the input file and store that as a permutation rules, and then continue reading the rest of the input file and store that separately as the text to be "permutated". And then eventually figure out how to apply the permutation to the text.
What is the result type? Obviously, it's up to me to decide this. As reference, consider the type promotion rules for native types:
Code: short a; int b; int result = a + b; In this case, the short value is promoted to the int value, and the addition happens on int.
It would seem a similar rule (go to the wider type) would be appropriate for fixed point. But there is another dimension to the problem, which is the number of fraction bits. Should you go to the wider type? Or the most precise type? Should you endeavor to minimize the number of bits which are discarded? What's the most intuitive rule?
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.
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?
Program is supposed to check for balanced parentheses which are (), {}, [] using a vector First read in the number of lines user wishes to testReturn Yes if balanced, No if unbalanced. 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:
#include <stdio.h> #include <stdlib.h> #include "char_vector.h" int main( int argc, char * argv []) { int i, num; char c; scanf("%d", &num); scanf("%c", &c);
