C++ Memory Mgmt

This lesson is part of C++ · All levels

Summary

This lesson explains memory management in C++, distinguishing automatic allocation on stacks from manual allocation on heaps. The keyword new is used to make objects in heap, while delete is used to release them back. This understanding is essential so that the program does not experience memory leaks or unauthorized memory access.

Key points

The local variable lives in the stack and is automatically released when the function is complete.
Heap is handled manually with new for allocation and delete for release.
Memory leaks occur when memory is allocated but never released.
Always make sure the pointer does not dangle after deletion.
