You can "communicate" with your variable in a heap by using the pointer:


              
123

            
int *x = new int;
*x = 42;
cout << *x;
copy

If the RAM space we use for our code runs out, the program will crash. Your RAM is not limitless, and after the program execution, we should always take care of clearing the area in memory that we originally allocated:

To clean the space in your code, use the keyword delete and the pointer, which contains the address of the memory we want to free:

delete x;

Remember! For each new operator should always exist delete!
