1. A showChar MethodWrite a method named showChar. The method should accept two arguments: a reference toa String object and an integer. The integer argument is a character position within theString, with the first character being at position 0. When the method executes, it shoulddisplay the character at that character position. The method does not return anything.Here is an example of a call to the method:showChar("New York", 2);In this call, the method will display the character w because it is in position 2.

C# Part 1: In your program, write a method that accepts a positive integer and returns true if the number is a prime number and false otherwise. Note that 2 is the only even prime number. An odd integer is prime if it not divisible by any odd integer less than or equal to the square root of the number. Part2: A prime number whose reversal is also a prime number is called emirp. For example, 11, 13, 79 and 359 are emirps. Write a program that outputs to a ListBox the first 100 emirps. Your program must contain the method from Part 1 that returns true if a number is prime; false otherwise and another method that returns the reversal of a positive number. You can reverse the integer in the following way: • Convert the integer into a string value = num.ToString(); • Use the following code to reverse the integer string newNum = “”; for (int l = value.Length; l > 0; l--) newNum = newNum + value[l-1]; Also, your program should have a TextBox that will accept a positive integer from the…

VBA - EXCEL Engine – optional – this indicates the solving method that needs to be used to get to a solution. 1 for the Simplex LP method, 2 for the GRG Nonlinear method, or 3 for the Evolutionary method. This corresponds to the Select a Solving Method dropdown list in the Solver Parameters dialog box EngineDesc – optional -this is an alternate way of selecting the solving method – here you would type the strings “Simplex LP”, “GRG Nonlinear” or “Evolutionary”. This also corresponds to the Select a Solving Method dropdown list in the Solver Parameters dialog box What happens when the code demonstrates: Engine:=1, EngineDesc:="GRG Nonlinear" ?
Write a method that accepts a string as an argument and checks it for proper capitalization and punctuation. The method should determine if the string begins with an uppercase letter and ends with a punctuation mark. The method should return true if the string meets the criteria; otherwise it should return false.
