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 is dynamic memory allocation done in C?
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.
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 moreDoes C support dynamic memory allocation?
Dynamic allocation is not supported by C variables ; there is no storage class “dynamic”, and there can never be a C variable whose value is stored in dynamically allocated space.
Read moreWhich header file is used for dynamic memory allocation in C?
Overview of functions The C dynamic memory allocation functions are defined in stdlib. h header ( cstdlib header in C++).
Read moreWhich header files are used for dynamic memory allocation functions?
Malloc, calloc, realloc and free functions are for dynamic memory allocation, which are stored in heap section. And in stdlib. h header file.
