Suppose your name was george gershwin. write a complete program that would print your last name, followed by a comma, followed by your first name. do not print anything else (that includes blanks).

I will write the code in C++ and JAVA      

Explanation:

public class Main

{public static void main(String[] args) {

       // displays Gershwin,George

     System.out.println("Gershwin,George");}  }

#include <iostream>

using namespace std;  

int main()

{  cout<<"Gershwin,George"; }    

// displays last name Gershwin followed by , followed by first name George

//displays Gershwin,George as output.

=> Code

public class Name{

    public static void main(String [ ] args){

          String firstname = "George";

          String lastname = "Gershwin";

          System.out.println(lastname + "," + firstname);

    }

}

=> Output

Gershwin,George

The code has been written in Java. The following is the line by line explanation of the code.

// Declare the class header

public class Name{

    // Write the main method for the code.

    public static void main(String [ ] args){

          // Declare a string variable called firstname and initialize it to hold the

          // first name which is George.

          String firstname = "George";

          // Declare a string variable called lastname and initialize it to hold the

          // last name which is Gershwin.

          String lastname = "Gershwin";

          // Print out the lastname followed by a comma and then the firstname

          System.out.println(lastname + "," + firstname);

    }      // End of main method

}           // End of class declaration

The explanation of the code has been written above as comments. Please go through the comments of the code for more understanding.

Nevertheless, a few things are worth noting.

(i) Since it is a complete program, a main class (Name, in this case) has to be defined. The main class has a main method where execution actually begins in Java.

(ii) The first name (George) and last name (Gershwin) are both string values therefore they are to be stored in a String variable. In this case, we have used variable firstname to hold the first name and lastname to hold the last name. Remember that variable names must not contain spaces. So variable names lastname and firstname, though compound words, have been written without a space.

(iii)The System.out.println() method is used for printing to the console in Java and has been used to print out the concatenated combination of last name and first name separated by a comma.

(iv) In Java, strings are concatenated using the + operator. To concatenate two strings lastname and firstname, write the following:

lastname + firstname.

But since they are separated by a comma, it is written as:

lastname + "," + firstname
