Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Find primes This program creates and displays a 5x10 matrix(5 rows and 10 columns) of random integers between 1 and a maximum value(user input). Hint: Use the random library to generate each number and place it into your 2D list. The program then counts the number of prime numbers in each row of the array and displays this number, along with the found primes. The program finally displays the total number of prime numbers in the matrix.

Alphabet Random Walk• Write a program to generate a random walk that spans a 10*10 character array (The initial values of the elements are all.). The program must randomly walk from one element to another, moving one element position up, down, left or right each time. The elements that have been visited are labeled with the letters A through Z in the order in which they were visited
