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.

According to mathematics: “A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself”. You should define a function which takes an integer as a parameter and returns it as a prime or not. Sample input: 13 Output: Prime 27 Output: Non- primeWrite a code for craps game. Craps is a dice game in which the players make wagerson the outcome of the roll, or a series of rolls, of a pair of dice.The rules of the dice game craps are as follows:You roll two dice. Each die has six faces, which contain one, two, three, four, five and six spots,respectively. After the dice have come to rest, the sum of the spots on the two upward faces iscalculated. If the sum is 7 or 11 on the first throw, you win and play is over. If the sum is 2, 3or 12 on the first throw you lose and play is over. If the sum is 4, 5, 6, 8, 9 or 10 on the firstthrow, that sum becomes your “point.” To win, you must continue rolling the dice until you“make your point” (i.e., roll that same point value). You lose by rolling a 7 before making yourpoint(in python)

Specifically, n lines should be printed out, the first consisting of a single asterisk, the second consisting of two asterisks, the third consisting of three, etc. The last line should consist of n asterisks. Thus, for example, if n has value 3, the output of your code should be******You should not output any space characters.The language we are using here is in Racket. Please enter the following code: (cond ((equal? 16 3) (+ 3 8)) ((equal? 16 8) 12) (else (* 6 3))) Write the return value for the above code. If replacing all of the 16's in the above code with 8, what is the return value? What about replacing the 16’s with 3? What does the cond function do?

Assign a value of 0 to a variable called between if n is less than -k or greater than +k; otherwise, assign 1. b. Assign a value of 1 to a variable called divisor if digit is a divisor of num; otherwise, assign a value of 0. c. Assign a value of 1 to a variable called lowercase if ch is a lowercase letter; otherwise, assign a value of 0.Write a c program dist.c that calculates the distance between two points and prints the result on the screen. The cartesian coordinates of the points would be given in the command line as 6 parameters. Your program should check if the number of arguments provided is correct and that the six coordinates are valid numbers of typedouble.dist.exe x1 y1 z1 x2 y2 z2For example, to calculate the distance between the two points (0, 0, 0) and (1, 1, 1), the program would be run as:dist.exe0 0 0 1 1 1and the screen output would be1.7320
- In C++ 2.12 LAB: Hypotenuse Given two numbers that represent the lengths of a right triangle's legs (sides adjacent to the right angle), output the length of the third side (i.e. hypotenuse) with two digits after the decimal point. Output each floating-point value with two digits after the decimal point, which can be achieved by executingcout << fixed << setprecision(2); once before all other cout statements. Ex: If the input is: 3.0 4.0 the output is: Hypotenuse: 5.00Use the Bash shell for the completion of this project.Develop a shell scripting application that allows the user to perform some advanced mathematicaloperations. Task 2: Find the terms of any linear sequence given by the rule Term = a*n + b, where a and b are integers specified by the user and n is a positive integer and print them in order (for example if the user inputs a=3, b=-4, the first few terms that should be printed are -1, 2, 5, 8, 11…). The user also will specify how many terms the program should print. In addition, the program should print the sum of terms found and a count of how many odd terms were found.Q2: Write a JavaScript function that accepts a number from a user as input and checks if the number is prime, then print True if the number is not a prime, print False. Note: A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself.
