Memory Management: Memory Allocation
In this lesson, we will learn about a subsection of memory management - memory allocation.
We'll cover the following
Introduction
Explicit memory management in C++ is highly complex, but it also provides us with great functionality. Unfortunately, this special domain is not as common in C++. For example, you can directly create objects in static memory, in a reserved area, or even in a memory pool. This functionality is often key in the safety-critical applications of the embedded world.
-
C++ enables the dynamic allocation and deallocation of memory.
-
Dynamic memory (heap) must be explicitly requested and released by the programmer.
-
You can use the operators
new
andnew[]
to allocate memory and the operatorsdelete
anddelete[]
to deallocate the memory. -
The compiler manages its memory automatically on the stack.
Smart pointers manages the memory automatically.
