c memory management example

How do you manage memory in C?
In C, the library function malloc is used to allocate a block of memory on the heap.
The program accesses this block of memory via a pointer that malloc returns.
When the memory is no longer needed, the pointer is passed to free which deallocates the memory so that it can be used for other purposes.
What is memory management in C ++\?
What Is C++ Memory Management? Memory management can be defined as a process in which management of a computer's memory occurs, for example assigning memory to programs, variables etc., in such a way that it doesn't affect the overall performance.
What is an example of a memory management system?
Single allocation is the simplest memory management technique.
All the computer's memory, usually with the exception of a small portion reserved for the operating system, is available to a single application.
MS-DOS is an example of a system that allocates memory in this way.
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.
