Java Programming For an array of 20 integers (Declare all necessary variable). Write separate code segments to do the following (NOT a whole complete program). *   Find and display the positive numbers whose values are less than 100.

In C++ language For number 2 through 4 create an integer array with 100 randomly generated values between 0 and 99; pass this array into all subsequent functions. Place code in your main to call all the methods and demonstrate they work correctly. Using just the at, length, and substr string methods and the + (concatenate) operator, write a function that accepts a string s, a start position p, and a length l, and returns a subset of s with the characters starting at position p for a length of l removed. Don’t forget that strings start at position 0. Thus (“abcdefghijk”, 2, 4) returns “abghijk” Create a function that accepts the integer array described above returns the standard deviation of the values in a. The standard deviation is a statistical measure of the average distance each value in an array is from the mean. To calculate the standard deviation, you first call a second mean function that you need to write (do not use a built in gadget. Then sum the square of the difference…

Consider a 3-by-4 integer array k. using java programming languagea) a statement that declares and creates k .b) How many rows and column does k have?c) How many elements does k have?d) access expressions for all the elements in row 3 of k .e) a single statement that sets the element of k in row 0 and column 1 to zero.f) individual statements to initialize each element of k to zero.g)  a nested for statement that inputs the values for the elements of k from the user.h) a series of statements that determines and displays the smallest value in k .i)  a statement that totals the elements of the third column of k . Do not use repetition.j) a series of statements that displays the contents of k in tabular format. List thecolumn indices as headings across the top, and list the row indices at the left of each row.

In c++, Declare a constant “ SIZE = 5 ” Declare an array of ints , of size SIZE . Initializethat array to have the values 10, 12, 15, 19, 6 .– Write a loop that calculates and prints out the minimum value of the array.– Write a loop that calculates and prints out the maximum value of the array.– Write a loop that calculates and prints out the average value of the array.
