Malloc(), calloc

calloc() function in C It is a dynamic memory allocation function which is used to allocate the memory to complex data structures such as arrays and structures . Malloc() function is used to allocate a single block of memory space while the calloc() in C is used to allocate multiple blocks of memory space.

Dynamic memory allocation This helps us avoid running into insufficient memory and makes us use the memory space efficiently. In the C programming language, two of the functions used to allocate and deallocate the memory during run-time are malloc() and free() , respectively.

In C, the library function malloc is used to allocate a block of memory on the heap . The program accesses this block of memory via a pointer that malloc returns. When the memory is no longer needed, the pointer is passed to free which deallocates the memory so that it can be used for other purposes.

malloc() Function in C library with EXAMPLE The malloc() function stands for memory allocation. It is a function which is used to allocate a block of memory dynamically . It reserves memory space of specified size and returns the null pointer pointing to the memory location. The pointer returned is usually of type void.26 Şub 2022
