Data Structures Questions
Dynamic memory allocation refers to the process of allocating memory at runtime, allowing programs to dynamically allocate memory as needed. It allows for the creation of data structures that can grow or shrink in size during program execution.
Dynamic memory allocation is typically used when the size of the data structure is not known at compile time or when the size may change during program execution. It allows for efficient memory utilization by allocating memory only when required and releasing it when no longer needed.
The process of dynamic memory allocation involves requesting memory from the operating system using functions like malloc() or new in C/C++ or Java, respectively. The allocated memory can then be used to store data.
On the other hand, dynamic memory deallocation refers to the process of releasing the memory that was previously allocated dynamically. This is done to free up memory resources and prevent memory leaks. The memory can be deallocated using functions like free() in C/C++ or delete in Java.
It is important to properly manage dynamic memory allocation and deallocation to avoid memory leaks or accessing invalid memory locations. Failure to deallocate dynamically allocated memory can lead to memory leaks, where memory is allocated but never released, resulting in inefficient memory usage.
