Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.

- (1) Prompt the user for a string that contains two strings separated by a comma. (1 pt) Examples of strings that can be accepted: Jill, Allen Jill , Allen Jill,Allen Ex: Enter input string:Jill, Allen (2) Print an error message if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. (2 pts)Ex: Enter input string:Jill AllenError: No comma in string. Enter input string:Jill, Allen (3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings. (2 pts)Ex: Enter input string:Jill, AllenFirst word: JillSecond word: Allen (4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit. (2 pts)Ex: Enter input string: Jill, Allen First word: Jill Second word: Allen Enter input string: Golden , Monkey First word: Golden Second word:…Assume that nextWord is a String variable that has been given a String value consisting entirely of letters. Write some Java code that outputs the message "First half of the alphabet", provided nextWord precedes "N" in alphabetic ordering. If nextWord does not precede "N" in alphabetic ordering, the code should output "Second half of the alphabet". (Note that "N" uses double quotes to produce a String value, as opposed to using single quotes to produce a char value.)PLEASE US SCHEME IN DRRACKET: In the language of an alien race, all words take the form of Blurbs. A Blurb is a Whoozit followed by between zero or more Whatzits. A Whoozit is the character 'x' followed by between one or more 'y's. A Whatzit is a 'q' followed by either a 'z' or a 'd', followed by a Whoozit.-The program should ask the user to “Enter an alien word:”, read the input as a string, and check whether or not it is a valid word (Blurb). If it is valid, it prints "The word is fine.", otherwise it prints "The word is a mess!". -The program should loop and ask the user for new input until they enter a valid blurb.
- Given the following local variable declarations: string s1 = "Welcome to C++ World"; string s2, s3; s2=s1; s3 = s1 + s2; What is the value of the following expressions (or ERROR)? cout<<s1<<endl; cout<<s2<<endl; cout<<s3<<endl; cout<<s1[1]<<endl; cout<<s1.length()<<endl; cout<<s1.at(1)<<endl;Given three int variables that have been given values, areaCode, exchange, and lastFour, write a string expression whose value is the string equivalent of each these variables joined by a single hyphen (-) So if areaCode, exchange, and lastFour, had the values 800, 555, and 1212, the expression's value would be "800-555-1212". Alternatively, if areaCode, exchange, and lastFour, had the values 212, 867 and 5309 the expression's value would be "212-867-5309".Q. Hi andre Write a Java program to check if a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward, ignoring spaces, punctuation, and capitalization. For example, "racecar" and "Madam" are palindromes, while "hello" and "Java" are not. Your program should take a string as input and return true if it's a palindrome, and false otherwise. Ok.
