String based program

String program #9 (Copy two strings)

Enter string: Imaginationhunt

Using Copy() function

str1 = Imaginationhunt

str2 = Imaginationhunt

ReferenceEquals: False

Equals: True

Using in-build Clone() function

str1 = Imaginationhunt

str2 = Imaginationhunt

ReferenceEquals: True

Equals: True

Using Assignment '=' operator

str1 = Imaginationhunt

str2 = Imaginationhunt

ReferenceEquals: True

Equals: True

The program for the string is written in C# programming language and will accept a string as input. The logic is to copy input string to some other variable and also check whether the reference of input string is equal to the copied string. There are three ways to copy strings:

1.    Using in-built function “Copy()”

2.    Using in-built function “Clone()”

3.    Using Assignment ‘=’ operator

Note: If you are new to C# and Console Application. Try to code First C# Program

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 String9     //copy two strings

    {

        static void Main(string[] args)

        {

            Console.Write("Enter string: ");

            string str1 = Console.ReadLine();

            string str2 = string.Empty;

            //Method-1: Using in-build Copy() function

            Console.WriteLine("\nUsing Copy() function");

            str2 = string.Copy(str1);

            Console.WriteLine("str1 = {0}", str1);

            Console.WriteLine("str2 = {0}", str2);

            Console.WriteLine("ReferenceEquals: {0}", Object.ReferenceEquals(str1, str2));

            Console.WriteLine("Equals: {0}", Object.Equals(str1, str2));

            //Method-2: Using in-build Clone() function

            Console.WriteLine("\nUsing in-build Clone() function");

            str2 = (string)str1.Clone();

            Console.WriteLine("str1 = {0}", str1);

            Console.WriteLine("str2 = {0}", str2);

            Console.WriteLine("ReferenceEquals: {0}", Object.ReferenceEquals(str1, str2));

            Console.WriteLine("Equals: {0}", Object.Equals(str1, str2));

            //Method-3: Using Assignment = operator

            Console.WriteLine("\nUsing Assignment '=' operator");

            str2 = str1;

            Console.WriteLine("str1 = {0}", str1);

            Console.WriteLine("str2 = {0}", str2);

            Console.WriteLine("ReferenceEquals: {0}", Object.ReferenceEquals(str1, str2));

            Console.WriteLine("Equals: {0}", Object.Equals(str1, str2));

            Console.ReadKey();

        }

    }

}

Output:

The input string here is “Imaginationhunt”. So, based on the input, program will copy the input string to some other variable and we also check whether both the variables are using the same reference or not. The output is shown below:

Enter string: Imaginationhunt

Using Copy() function

str1 = Imaginationhunt

str2 = Imaginationhunt

ReferenceEquals: False

Equals: True

Using in-build Clone() function

str1 = Imaginationhunt

str2 = Imaginationhunt

ReferenceEquals: True

Equals: True

Using Assignment '=' operator

str1 = Imaginationhunt

str2 = Imaginationhunt

ReferenceEquals: True

Equals: True
