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.

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.

Read moreWhat are the types of dynamic memory allocation?
Dynamic Memory Allocation is a process in which we allocate or deallocate a block of memory during the run-time of a program. There are four functions malloc(), calloc(), realloc() and free() present in <stdlib.
Read moreWhat is dynamic memory allocation example?
ptr = (cast-type*) malloc(byte-size) For Example: ptr = (int*) malloc(100 * sizeof(int)); Since the size of int is 4 bytes, this statement will allocate 400 bytes of memory. And, the pointer ptr holds the address of the first byte in the allocated memory.9 Ara 2021
Read moreWhat is the static memory allocation in C?
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.
