12. Heap memory

• Heap is where the dynamically allocated variables are stored in a C program.

• C++ uses its own facility named free store to dynamically allocate memory.
  For example,

  
  #include <iostream>
  
  int main()
  {
      std::cout << "how many numbers would you like to allocate? ";
      int count;
      std::cin >> count;
      int* memory_block = new int[ count ];
      std::cout << "your block of memory begins at address " << memory_block << '\n';
      return 0;
  }
