11.3 delete Keyword

To delete an object created with the new keyword from memory, the delete keyword can be used. For each object created with new there should be a corresponding deletion using delete. Otherwise, objects not deleted are sometimes left lingering in memory, hogging more and more resources. This is called a memory leak, which can be the cause of many errors. Consider the following code for the creation and deletion of an object in memory.

      #include <iostream>      int main()      {         int *Number = new int;         *Number = 5;         std::cout<<*Number;         delete Number;         return 0;      }
