Answer 1

you allocate memory using the new operator and release a pointer using delete operator. Note that you can't delete normal variables, only pointers and arrays can be deleted after accomplishing their task.

int * foo;
foo = new int [5];
delete[] foo;

a complete program

#include 
#include 
using namespace std;

int main ()
{
  int i,n;
  int * p;
  cout << "How many numbers would you like to type? ";
  cin >> i;
  p= new (nothrow) int[i];
  if (p == nullptr)
    cout << "Error: memory could not be allocated";
  else
  {
    for (n=0; n> p[n];
    }
    cout << "You have entered: ";
    for (n=0; n

result

How many numbers would you like to type? 5
Enter number : 75
Enter number : 436
Enter number : 1067
Enter number : 8
Enter number : 32
You have entered: 75, 436, 1067, 8, 32,
