String based program

String program #12 (validate whether Password contain same 3(three) characters which exist in UserId)

Enter UserId: easytrip

Enter Password: hjabcfhj

O/p: -
Password accepted

The program for the string is written in C# programming language and will accept two strings as input. The logic is to check whether Password contain UserId. If yes, then the code must validate that password.

Note: Read articles on how to use Loops and Conditions.

Let’s find out a simple and easy way to code the program.

Practical Implementation:

using System;

namespace patternProblem.String

{

    class String12      //validate whether Password contain same 3(three) characters which exist in UserId

    {

        public static void Main()

        {

            Console.Write("Enter UserId: ");

            string txt_login_value = Console.ReadLine();

            Console.Write("Enter Password: ");

            string txt_pswd_value = Console.ReadLine();

           

            String12 obj = new String12();

            if (obj.UserIdContainSameThreeCharacterInPassword(txt_login_value, txt_pswd_value) == false)

            {

                Console.WriteLine("Invalid! Password contain same 3(three) characters which exist in UserId");

            }

            else {

                Console.WriteLine("Password accepted");

            }

        }

        public bool UserIdContainSameThreeCharacterInPassword(string txt_login_value, string txt_pswd_value)

        {

            for (int i = 0; i < txt_login_value.Length - 2; i++)

            {

                for (int j = 0; j < txt_pswd_value.Length - 2; j++)

                {

                    if (txt_login_value.Substring(i, 3) == txt_pswd_value.Substring(j, 3))

                    {

                        return false;

                    }

                }

            }

            return true;

        }

    }

}

Output:

So, based on the input UserId and password, program will check whether password contain same 3 characters that exist in UserId.

The output is shown below:

Case-1: Password is not same

Enter UserId: easytrip

Enter Password: hjabcfhj

Password accepted

Case-2 When password contain similar 3 characters that exist in UserId

Enter UserId: ghabcdkhabcdjabcf

Enter Password: hjabcfhj

Invalid! Password contain same 3 three characters which exist in UserId
