the code use in above link is good but one problem i cant able to use backspace to remove mistake if user made any mistake he cant able to remove the mistaken character
In the following char array, notice the use of a backspace character in a string literal: ''.
char text1[50] = "aHello,
World! Mistakee was "Extra 'e'"!
";
What exactly does a backspace character do here? When the compiler evaluates this line, does it actually delete the previous character, like when you press the backspace button on the keyboard?
I'm making a calculator project but i can't find a solution for backspace button ,, i used these code -->
TxtNumber.Text.Remove(0,1);
But it removed the first number i wrote in the TxtNumber(TextBox) not the last one !!!!
How to avoid using Backspace character with push_back? I'm making a software as an ATM, so when the user try to enter the password the user only sees *******, but when trying to delete it doesn't delete a character. It just adds a new one. Here's my code:
string password2 = "";
cout << "PASSWORD: ";
ch = _getch();
while(ch != 13) //character 13 is enter {
password2.push_back(ch);
cout << '*';
ch = _getch();
}
And also, I try to use pop_back(); but it doesn't work either.
how work backspace key in c++.i want to make a program which can work as a backspace number

I think that the problem is in the array declaration but i'm checking resources and no success!

I am trying to read a "password" from a file, the file only contains the password... Here is my code:
int i=0, ch;
char password[25];
FILE *fp = fopen("C:UsersOlintoDocumentsNetBeansProjects est.txt", "r");
if (fp == NULL)
printf("Erro ao Abrir");
[Code] ....
puts(password); When I read the string password, it outputs -> abcd123"
I don't know where it takes the (") because the password on the file is abcd123...
this is really important i searched an example code about "Username and Password Validation between Server and Client" through internet a LOT and i couldn't find anything..

After this what should I put to complete this program?
Okay, so I have a science fair project and I decided on doing a series of programs that show the simpleness behind hacking a password. Each program increases in complexity starting with a four digit password, and ending with a 10 digit letter and number combo that is case sensitive. Right now I need to figure out a way to have my program be able to convert chars into ints, so that I can do a counter and then I also need to be able to convert the ints, back into chars.

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'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.

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.
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
