Question

Write a C++ program that does the following :

1. Accepts array size from the keyboard. The size must be positive integer that is >= 5 and <= 15 inclusive .

2. Use the size from step 1 in order to create an integer array. Populate the created array with random integer values between 10 and 200.

3. Display the generated array.

4. Write a recursive function that displays the array in reverse order .

5. Write a recursive function that returns a result of a number raised to a power. The function should take two arguments, the number to be raised to the power is the last number in array and the power is 2.

6. Write a recursive function that displays squares of integers in ascending order, starting from 1 to the first number in the array.

7. Write a recursive function that displays the second number in the array vertically .

8. Write a recursive function that returns true if the digits of the third number in the array is in increasing order ; otherwise , the function returns false.

9. Write a recursive function that takes the fourth number in the array and returns the numbers with the digits reversed.

10. Write a recursive function that determines and returns true or false to whether or not the fifth number in the array is a prime number
