Step by step
Solved in 2 steps
- Are both variables p1 and p2 pointers if p1 and p2 are defined as follows: double* p1, p2;Dangling and wild pointers are known to be problems with pointers Justify given statement with the help of given examplesc++ Write a function named “countTheSameAsLast” that accepts an array of pointers to class objects (class “example”) and its array size. It will go through the array and return how many elements (int) in the array are the same as the last element and whether the first and the last elements are the same or not (bool).
- write in c++ Write ONE program that contains the following (#includes are NOT necessary). [Hint: be very careful with your pointer syntax] Write a function copies with two int parameters, named n and x. It should dynamically allocate a new array of size n. The function should then copy the value in x to every position in the array. The function should return a pointer to the new array. In the main function, call the copies function from part 1. with size 5 and value -1. Output the resulting array to the screen, and deallocate the array. In your main function, add code to declare and initialize two integer variables y and z to 10 and 3. Then call the function increment which has the prototype below. The call should result in incrementing the value in y by z (so y will become 13). void increment (int *a, int b); //do NOT define this function// this function adds b to the value pointed to by the first argumentc++ make a simple prrogram that takes random 2d array entered by user and organizes it use pointers for example if the user enter ((8,4),(3,4),(7,2),(8,6),(3,1)) no limit to number of sets use pointers there should be a function called transformer that will transform them into the right order and a funtion called display that will display what was inputed then it would organize it into ((4,8),(3,4),(2,7),(6,8),(1,3)) IT should only modify it and not make a copy of it.Use pointers to add two array
