-1 is not a valid index. so, nums[-1] will give an error.
pointer variable contains address of a location in main memory. so, it contents of the pointer can only be checked at the run-time.

Question 1 When you declare a variable of type Single, it contains 0 by default. True False Question 2 The following line declares an array that can contain whole numbers, with 10 elements. Dim Variables(9) As Integer True False Question 3 Once a variable is declared we can not change the variable's data type. True False Question 4 If A is False and B is True, then A Or B is True because A is False. True False Question 5...
(C++ program )Write a function that accepts an int array and the array’s size as arguments. The function should create a new array that is one element larger than the argument array. The first element of the new array should be set to 0. Element 0 of the argument array should be copied to the element 1 of the new array. Element 1 of the argument array should be copied to element 2 of the new array, and so forth....
C++ pointers and linked lists 1. Declare an integer pointer variable intPointer. Initialize it to point to an int variable named someInt. Assign the value 451 to someInt and output (cout) the variable someInt and output (cout) the value pointed to by intPointer. Write an assignment statement that indirectly stores 900 into the value pointed to by intPointer. Output (cout) the value pointed to by intPointer and output (cout) the variable someInt, 2. Declare a pointer variable charArrPointer and initialize...
Write C++ code that creates an integer variable called number. Dereference a given pointer gPointer and places that value into the variable number. The pointer gPointer will have been declared and set to point to a value before your code runs. Your code will be placed inside the main function with all the appropriate #includes. After your code runs, the test case will execute the following code: cout << "number = " << number << endl; For example: Test Result...

Assume the following declarations have been made in main(): int howmany; Scanner kb = new Scanner(System.in); Random r = new Random(); Write code to do the following: Use a while loop to prompt the user for how many numbers are to be entered. If the user does not enter a positive number (a number greater than 0), display a message saying the number must be positive and to try again. Store this value in the howmany variable. Declare an integer...

TRUE/FALSE 1. If pl is an integer pointer variable, with the value of 1000, pl++ changes P1 to point to the memory location 1001. ANSWER: T 2. When you return a dynamic array to the freestore, you must include the number of elements in the array 3. You can assign an array to a pointer variable. 4. The size of dynamic arrays must be declared at compile time. 5. int *pl; declares a static variable. ANSWER: F ANSWER: F ANSWER:...
