CS201 Short Lecture - 27 | VU Short Lecture | Memory Leak & Dangling Pointers in (Urdu / Hindi)

Описание: In programming, memory allocation is an important concept as it deals with the allocation and deallocation of memory resources for data storage during program execution. Dynamic memory allocation is a technique that allows a program to request memory resources from the system's memory pool at runtime. However, if not managed properly, it can result in memory leaks and dangling pointers.

In lecture 27, the focus is on memory allocation, memory leaks, and dangling pointers. The lecture begins by discussing the differences between static and dynamic memory allocation, where static memory allocation involves allocating memory during compile time and dynamic memory allocation involves allocating memory during runtime.

The lecture then moves on to the concept of memory leaks, which occur when memory is allocated but not properly deallocated, resulting in a waste of memory resources. The causes and consequences of memory leaks are explained, along with common programming practices that can lead to memory leaks.

Dangling pointers, another important concept in memory management, are also discussed. Dangling pointers occur when a pointer points to a memory location that has been deallocated or when a pointer is used before being initialized. The lecture covers the dangers of using dangling pointers and the importance of avoiding them in programming.

Finally, the lecture covers techniques for managing memory resources, including the use of functions such as calloc, malloc, and free to allocate and deallocate memory, as well as best practices for managing memory in C++ programs.
