1) Write a complete program that will have a main function and a function called twice. (Hint: See Fig 8.7) a. Write a function named twice whose only parameter is an integer pointer. b. This function doubles the value stored at the location pointed by the pointer parameter c. In the main method, declare an integer variable mm and in itialize it to 5. Call the function twice from main such that the function twice will double the value of mum. d. In the main method and after calling the function, print the variable num. 2) For each of the following, write C++ statements that perform the pecified task. (Ref classwork named pointer2) a) Declare a built-in array of type unsigned int called values with five elements, and initialize the elements to the even integers b) Declare a pointer vPtr that points to a variable of type un- c) Write two separate statements that assign the starting address d) Use a for statement to print the elements of array values using e) Refer to the fifth element of values using pointer subscript no- from 2 to 10. signed int. of array values to pointer variable vPtr. pointer/offset notation. tation
