Dynamic memory allocation is a process that allows us to do exactly what we’re looking to do above, to allocate memory while our program is running, as opposed to telling the computer exactly how much we’ll need (and for what) ahead of time.
Read moreWhat is dynamic memory example?
Example-: int *ptr; ptr=(int *)malloc(8); This allocates 8 contiguous bytes of memory space and the address of first byte is stored in the pointer variable ptr . This space can hold 4 integers. Unlike memory allocated for variables and arrays, dynamically allocated memory has no name associated with it.
Read moreHow allocate memory dynamically in C++ explain with example?
You can allocate memory at run time within the heap for the variable of a given type using a special operator in C++ which returns the address of the space allocated . This operator is called new operator.

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.
Read moreWhat is the difference between dynamic and static memory?
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 .
Read moreWhat is dynamic allocation and static allocation?
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
