{

string str;

cout<<"Enter the string: ";

cin>>str;

str[i]='x';

}

cout<<"the string is: "<<str<<endl;

return 0;

}

Explanation:

First, include the library iostream for using the input/output instructions.

Create the main function and declare the variables.

Then, use the cout instruction and print the message on the screen.

cin store the string enter by the user into a variable.

After that, take a for loop and if-else statement for checking the condition if the string contains the 'e', then change that alphabet to 'x'.

This process continues until the string not empty.

If a user's input string matches a known text message abbreviation, output the unabbreviated form, else output: Unknown. Support

Molodets [167]

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.

The alt attribute is not mendatory attribute in image tag.The alt attribute display the message when image is not visible in the web page .

All the other attribute like alt,height,width are used as per the requirement but src is an required attribute .
