Your task is to design Dynamic Array (Class). What is Dynamic Array? Which can grow and shrink at run time. Your class should work for one and two dimensional Arrays The class should enable the user to perform the following tasks: 1) Create a dynamic array of size specified by the user. Use an integer to keep track of the size 2) Ask the user for numbers to insert until the user presses -1. Insert each value in the array. Create a new larger array when the array is full, copy all data to the new array, and release the memory for the old array. Print the array after each insert. 3) Ask the user for any numbers to delete until the user presses - 1. Find the index of the

(Program) Write a declaration to store the following values in an array named rates: 12.9, 18.6, 11.4, 13.7, 9.5, 15.2, and 17.6. Include the declaration in a program that displays the values in the array by using pointer notation.

In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.
