Syntax of the Free() Function in C Language void free(void *ptr); Description of the Free() Function in C Language The free() function frees a specified amount of dynamically allocated memory. The dynamic memory is allocated by calling the malloc() function and specifying the size in bytes...
When a memory block is allocated using std::malloc, std::calloc or std::alloc.a pointer is returned. This pointer is passed to free function, for deallocation. This helps in memory management for the compiler dynamically. In case the pointer is a null pointer then function does nothing as...
