Question

If a user's input string matches a known text message abbreviation, output the unabbreviated form, else output: Unknown. Support two abbreviations: LOL -- laughing out loud, and IDK -- I don't know
Sample input/output:

Input an abbreviation: LOL
laughing out loud

Answer 1

Answer:

LOL = "laughing out loud"

IDK = "i don't know"

BFF = "best friend forever"

text = input("input a known text message abbreviation: ")

if text == "LOL":

        print(LOL)

elif text == "IDK":

        print(IDK)

elif text == "BFF"

        print(BFF) 

else:

        print("unknown")

Explanation:

The code is written in python.  And I added another abbreviation apart from the required 2(BFF)

LOL = "laughing out loud"

This line of code equate the string "laughing out loud " to the variable LOL.

IDK = "i don't know"

This line of code equate the string "i don't know " to the variable IDK.

BFF = "best friend forever"

This line of code equate the string "best friend forever" to the variable BFF.

text = input("input a known text message abbreviation: ")

This code prompt the user to input the text message abbreviation.

if text == "LOL":

If the text the user inputted is LOL.

print(LOL)

This code print out the variable LOL.

elif text == "IDK":

else if the inputted is IDK

print(IDK)  

Display the variable IDK

elif text == "BFF"

else if the inputted text is BFF

print(BFF) 

display the variable BFF

else:

Otherwise

print("unknown")

display the text "unknown"

Answer 2

Answer:

Here is the JAVA program. I  have added a few more abbreviations apart from LOL and IDK.

import java.util.Scanner; // to take input from user

public class MessageAbbreviation {

public static void main(String[] args) { //start of main() function body

   Scanner input = new Scanner(System.in); // create object of Scanner

       String abbreviation= ""; //stores the text message abbreviation

/* In the following lines the abbreviation string type variables contain the un-abbreviated forms */

           String LOL = "laughing out loud";

           String IDK = "i don't know";

           String BFF = "best friends forever";

           String IMHO = "in my humble opinion";

           String TMI = "too much information";

           String TYT = "take your time";

           String IDC = "I don't care";

           String FYI = "for your information";

           String BTW = "by the way";

           String OMG = "oh my God";

//prompts the user to enter an abbreviation for example LOL

           System.out.println("Input an abbreviation:" + " ");

           if(input.hasNext()) { // reads the abbreviation form the user

           abbreviation= input.next(); }

// scans and reads the abbreviation from user in the abbreviation variable

/*switch statement checks the input abbreviation with the cases and prints the un abbreviated form in output accordingly. */

    switch(abbreviation) {

       case "LOL" : System.out.println(LOL);

                    break;

       case "IDK" : System.out.println(IDK);

                    break;

       case "BFF" : System.out.println(BFF);

                    break;

       case "IMHO": System.out.println(IMHO);

                     break;

       case "TMI": System.out.println(TMI);

                     break;

       case "TYT": System.out.println(TYT);

                     break;

       case "IDC": System.out.println(IDC);

                     break;

       case "FYI": System.out.println(FYI);

                     break;

       case "BTW": System.out.println(BTW);

                     break;

       case "OMG": System.out.println(OMG);

                     break;

                     

       default    : System.out.println("Unknown"); } } }

Explanation:

The program first prompts the user to enter an abbreviation. Lets say the user enters LOL. Now the switch statement has some cases which are the conditions that are checked against the input abbreviation. For example if the user enters LOL then the following statement is executed:

case "LOL" : System.out.println(LOL);

This means if the case is LOL then the message ( un abbreviated form) stored in the LOL variable is displayed on output screen So the output is laughing out loud.

Anything else entered other than the given abbreviations will display the message: Unknown

The output is attached as screen shot.
