What is memory management in C language?
Memory management, or memory allocation, is the process by which computer programs are assigned to physical or virtual memory space.
Computer memory is a finite resource that must be efficiently managed.
The memory allocation can be done either before or at the time of program implementation.13 sept. 2021Does C use automatic memory management?
In C and C++, memory allocated on the heap is managed manually.
In C# and Java, however, memory allocated on the heap is managed automatically.In C, dynamic memory is allocated from the heap using some standard library functions.
The two key dynamic memory functions are malloc() and free().
The malloc() function takes a single parameter, which is the size of the requested memory area in bytes.
It returns a pointer to the allocated memory.
Do you need to manage memory in C?
All of the memory allocated to these variables is automatically managed by C, meaning that you do not need to (and should not) use any of the C stdlib 's memory management functions on them.
In most cases, your source code will consist of automatically managed variables.
