- A pointer variable cannot be: A Passed to a function as argument. B B Changed within the funcction. C Returned by a function. D Assigned as an integer value. Darrow_forward1. Pointer Tasks This part of the assignment will give you a chance to perform some simple tasks with pointers. The instructions below are a sequence of tasks that are only loosely related to each other. Start the assignment by creating a file named pointerTasks.cpp with an empty main function, then add statements in main() to accomplish each of the tasks listed below. Some of the tasks will only require a single C++ statement, others will require more than one. For each step, include a comment in your program indicating which step you are completing in the following statement(s). The easiest way to do this is copy and paste the below into your main function first, and then fill in your statements. // 1. Create two integer variables named x and y// 2. Create an int pointer named p1// 3. Store the address of x in p1// 4. Use p1 to set the value of x to 99// 5. Using cout and x, display the value of x// 6. Using cout and the pointer p1, display the value of x// 7. Store the address…arrow_forwardWhat is the connection between a reference and a pointer?arrow_forward
- Declare an integer pointer variable intPointer. Initialize it to point to an int variablenamed 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,arrow_forwardWhat is a pointer? How do you dereference a pointer to get its stored value?arrow_forwardA pointer variable is O the same thing as an array subscript dereferences a pointer and allows access to the value of the variable the pointer points to an operator that returns the memory address of a variable a variable that holds an addressarrow_forward
- Memory Management Programming Assignment Please if this can be coded in Java or C++ i would appreciate implement and test the GET-MEMORY algorithm This algorithm uses the Next-Fit(First-Fit-With-A-Roving-Pointer) technique. implement and test the FREE-MOMORY algorithm Implement the “GET_MEMORY” and “FREE_MEMORY” algorithms. Comprehensive testing must be done for each algorithm. Following are sample run results for each: GET_MEMORY IS RUNNING……… Initial FSB list FSB# Location Size 1 7 4 2 14 10 3 30 20 . . . . . . Rover is 14 ---------------------------------------------------------------------------- Allocation request for 5 words Allocation was successful Allocation was in location 14 FSB# Location Size 1 7 4 2 19 5 3 30 20 . . . . . . Rover is 30 ---------------------------------------------------------------------------- Allocation request for 150 words Allocation was not successful . . . __________________________________________________________ FREE_MEMORY…arrow_forwardIn C, in order to do operations to the data being referenced by a pointer you would need to use the (*) operator, which is called ______________ operator.arrow_forwardIn order to declare a pointer, the ""&"" (ampersand) symbol is used."
