Explore dynamic memory allocation from "summary" of C/C++ Programmer's Reference by Herbert Schildt
Dynamic memory allocation is a powerful feature provided by C and C++. It allows you to allocate memory at run time, rather than at compile time. This gives you more control over memory management and enables you to create more flexible and efficient programs. When you allocate memory dynamically, you use functions such as malloc(), calloc(), or new to request a block of memory from the system. The system then returns a pointer to the allocated memory, which you can use to access and manipulate the memory block. One of the main advantages of dynamic memory allocation is that it allows you to create data structures of varying sizes and shapes. For example, you can create arrays, linked lists, trees, and other complex data structures that can grow and shrink as needed. This flexibility is especially useful when working with input data of unknown size, or when dealing with complex computations that require a lot of memory. However, dynamic memory allocation also comes with some challenges. For one, you are responsible for managing the allocated memory yourself. This means that you must remember to release the memory when you are done using it, to prevent memory leaks. Failure to do so can lead to wasted memory and performance issues in your program. Another challenge is that dynamic memory allocation can be error-prone if not done carefully. For example, if you access memory that has already been released, you may encounter a segmentation fault or other runtime errors that can crash your program. To avoid these issues, it is important to follow best practices and use memory allocation functions correctly.- Dynamic memory allocation is a valuable tool that can help you create more flexible and efficient programs. By understanding how it works and how to use it effectively, you can take full advantage of this feature in your C and C++ programs.
