In languages like C and C++, memory management plays a crucial role in ensuring efficient utilization of system resources and preventing memory-related issues such as memory leaks and segmentation faults. Here are some key concepts and techniques for handling memory management in these languages:

Manual Memory Allocation and Deallocation:

• In C and C++, memory allocation and deallocation are primarily managed using functions like malloc, calloc, realloc, and free.
• When allocating memory using malloc or calloc, remember to free the allocated memory using free to prevent memory leaks.
• Always check for the return value of memory allocation functions to ensure that memory is allocated successfully.

Dynamic Memory Allocation:

• C and C++ allow for dynamic memory allocation, where memory is allocated at runtime based on the program's requirements.
• Dynamic memory allocation is useful when the size of data structures is not known at compile time or when memory needs to be allocated and deallocated dynamically during program execution.

Memory Leak Detection:

• Memory leaks occur when memory allocated dynamically is not deallocated properly, leading to a gradual depletion of available memory.
• Use debugging tools and memory leak detection tools such as Valgrind (for C/C++) or AddressSanitizer (for C++) to identify and fix memory leaks in your code.

Smart Pointers (C++):

• C++ introduces smart pointers such as std::unique_ptr, std::shared_ptr, and std::weak_ptr to automate memory management and avoid manual memory deallocation.
• Smart pointers automatically handle memory deallocation when they go out of scope, making them safer alternatives to raw pointers.

RAII (Resource Acquisition Is Initialization):

• RAII is a programming idiom commonly used in C++ to ensure that resources, including dynamically allocated memory, are properly managed and released.
• RAII relies on the principle that resources should be acquired during object initialization and released during object destruction, thereby tying resource management to object lifetimes.

Avoiding Memory Corruption:

• Memory corruption issues such as buffer overflows and dangling pointers can lead to unpredictable behaviour and security vulnerabilities.
• Practice defensive programming techniques such as bounds checking, proper initialization of variables, and validating user input to minimize the risk of memory corruption.

Static Memory Allocation:

• In addition to dynamic memory allocation, C and C++ support static memory allocation, where memory is allocated at compile time and remains fixed throughout the program's execution.
• Static memory allocation is suitable for allocating memory for variables with a fixed size or lifetime, such as global variables or variables declared with the static keyword.
