- 4. Declare an int pointer that points to another pointerAnswer:•• R7.10Pointers are addresses and have a numerical value. You can print out the value of a pointer as cout << (unsigned)(p). Write a program to compare p, p + 1, q, and q + 1, where p is an int* and q is a double*. Explain the results.What is void pointer? Give Example code ?
- 6. Write a swap function, that swaps the values of two variables in main, but usepointers instead of reference parameters.7. Write a function that takes an array of ints and its size as arguments. It shouldcreate a new array that is the same size as the argument. It should set the values inthe new array by adding 10 to each element in the original array. The functionshould return a pointer to the new array. (Make sure you use dynamic memoryallocation) can i get answers for this two sub parts. thanksWhen calling a swap function to swap the value of the two arrays, how do I add the reference to the calling statement without giving me an error? Also, I have to use pointers for this assignment. Here is the code: const int S = 10; //Pre-condition: two c strings of the same size //Post-condition: swap the values of the c strings void swapArr(char array1[ S], char array2[ S]) { int size = 0; for (int i = 0; array1[1] != '\0'; i++) { size++; } char* value = new char; value = new char [size]; //Loop fusion for (int i = 0; i < size; i++) { //Swap the values value[i] = array1[i]; array1[i] = array2[i]; array2[i] = value[i]; } } int main(){ char array1[S]= { "Hello" }; char array2[S] = { "World"}; //For some reason the swap function is not working swapArr(& array1[S], & array2[S]); for (int i = 0; array1[i] != '\0'; i++) { std::cout << array1[i]; } }Pointers are by default passed by value in a function. Group of answer choices True False ================= Given the below code segment, which of the following would allow you to deallocate all memory allocated to the pointer numbers? int* numbers = new int[5]; Group of answer choices delete[] numbers; delete numbers; delete[5] numbers; None of these ========== Consider the following code: int arr[][4] = { {1, 2, 3, 4}, {7, 8, 9, 10} }; cout << arr[1] << endl; What will be the output? Group of answer choices 1 7 Address of 1 Address of 7 Compilation error: Second [] bracket missing with arr
- a) Write a c++ program which contains a function isPalindrome, the function checks a stringusing pointers whether it is a palindrome or not and based on the decision return Ture orFalse. A string/word that reads the same backwards as forward is known as palindrome.E-g MADAM , POP , BOB etcb) Write a program that takes a char array (char *) that take your name as input, a charpointer point it and convert lower to upper and vice versa.1. Write a function named “getSumBeforeNegative” that takes in a pointer to the array of integers and its size. It will return the sum of all values before it sees a negative number. If there is no negative number in the list, it returns the sum of all numbers in the array.For example,int numList[] = {10,20,-1, 30);// will return 30int priceList[] = {10, 20, 30);// will return 60It must use pointers to integer instead of array index.Write a main program and show how this function is called and used.Assuming a char requires one byte, an int requires four bytes, and a pointerrequires four bytes, (a) How much storage does something of type struct studenttake? (assume only the items given) (b) How much storage does the variable pStudenttake? (c) How much storage does ptrs take if it is declared as struct student *ptrs[10] (array of pointers to students)? C Programming Please!
- The following code C++ uses pointers and produces two lines of output. What is the output? int v1 = 10; int v2 = 25; int* p1 = &v1; int* p2 = &v2; *p1 += *p2; p2 = p1; *p2 = *p1 + *p2; cout << v1 << " " << v2 << endl; cout << *p1 << " " << *p2 << endl; find line 1 and 2.1] When does the void pointer can be dereferenced? A.when it doesn't point to any value B.when it cast to another type of object C. using delete keyword D. none of the mentionedIn C programming: Write a function printAllCourses() which receives an array of course pointers and the array’s size, then prints all courses in the array by calling printCourseRow()
