- Using C++ Programming language: Assume the following definition in the main() function: const int SIZE = 5; const int nums[SIZE] = { 18, 17, 12, 14, 16 }; Assume the following function call: numFunc(nums, SIZE); Write the function header that accepts these function call arguments without error. Use pointer notation for the array.arrow_forwardA 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_forward
- python only** define the following function: This function must set the value of a task in a checklist to True. It will accept two parameters: the checklist object to add to, and the name of the task to mark as completed. In addition to changing the task value, it must return the (now modified) checklist object that it was given. if the task name provided is not in the checklist, this function must print a specific message and must return None. Define completeTask with 2 parameters Use def to define completeTask with 2 parameters Use a return statement Within the definition of completeTask with 2 parameters, use return _ in at least one place.

If 1 is the only common divisor, the function should print a statement indicating the two numbers are relatively prime. Otherwise, the function prints the number of common divisors and the list of common divisors. Complete each to do with comments to expalin your process. Problem part 2: complete the following todo's and make comments to explain each step # TODO: Define the function 'common_divisors' with two arguments 'm' and 'n'. # TODO: Start with an empty list and append common divisors to the list. # TODO: Create a conditional statement to print the appropriate statement as indicated above.
