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:...
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...

2) For each of the following, write C++ statements that perform the specified 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 from 2 to 10. b) Declare a pointer vPtr that points to a variable of type unsigned int. c) Write two separate statements that assign the starting address of array values to pointer variable vPtr. d) Use...
Assume that integer array b[5] and integer pointer variable bPtr have been defined. Write a statement to set bPtr equal to the address of the first element in array b. Write a statement using pointer expression to reference the array element b[3]. please make sure answer should be detailed , correct and in C language.

3. (40 pts) Define an array fof size 10, using call-by-reference (that is, use of pointers), to pass the array to a function, named summation In main: define array, pass array, print out the array and the results on screen In function summation: take array from main and sum the array using the formula below: 10 fO 2 246 NOTE: you must use call-by-reference (the pointer) to call functions, as required; otherwise, no credits will be given.
a) Declare and instantiate an array named scores of twenty-five elements of type int. (b)Write a statement that declares an array namedstreetAddress that contains exactly eighty elements of typechar. 2. In a single statement: declare, create and initialize an arraynamed a of ten elements of type int with the values of the elements (starting with the first) set to 10, 20,..., 100 respectively. 3. Declare an array reference variable, week, and initialize it to an array containing the strings "mon",...
Write the code to dynamically allocate ONE integer variable using calloc (contiguous allocation) or malloc (memory allocation) and have it pointed to by a pointer (of type int * ) named ptr_1. Use ptr_1 to assign the number 7 to that dynamically allocated integer, and in another line use printf to output the contents of that dynamically allocated integer variable. Write the code to dynamically allocate an integer array of length 5 using calloc or malloc and have it pointed...
