Lesson 3.3

• The heap


  Unused memory of the program that can be used to allocate memory dynamically when the program runs
• Dynamic memory in C++

  Memory in C++ program is divided into two parts: the stack and the heap
• Allocation


  1. Use the new operator to allocate a block of memory of a specific size for a particular data type

  2. The new operator returns a pointer to the allocated memory block

  3. Explicitly specify the size of the memory you want to allocate
• Static memory


  Memory allocated at compile time
• Deallocation


  1. Use the delete operator to deallocate memory that was previously allocated with new

  2. Deallocate memory when you're done using it to avoid memory leaks
• Dynamic memory


  Memory that can be allocated and deallocated during the runtime of a program
• The stack


  Variables declared inside a function take up memory from the stack
