What is dynamic allocation and static allocation?

Static variable defines in one block of allocated space, of a fixed size . Once it is allocated, it can never be freed. Memory is allocated for the declared variable in the program. The address can be obtained by using ‘&’ operator and can be assigned to a pointer.

The key difference between static and dynamic memory allocation is that in static memory allocation once the memory is allocated, the memory size is fixed while in dynamic memory allocation, once the memory is allocated, the memory size can be changed .

In static memory allocation, once the memory is allocated, the memory size can not change. In dynamic memory allocation, when memory is allocated the memory size can be changed .12 Ağu 2021
