Introduction to calloc() Thecalloc()function in C stands for contiguous allocation. It is used to dynamically allocate memory for an array of elements, initialize them to zero, and then return a pointer to the memory. Syntax void* calloc(size_t num, size_t size); ...

Functions likemalloc(),calloc(),realloc(), andfree()are used for dynamic memory management. Whilemalloc()andcalloc()are for allocation,realloc()adjusts previously allocated size, andfree()deallocates memory. Importance of Memory Deallocation ...
memkind_calloc() allocates space for num objects, each are size bytes in length. The result is identical to calling memkind_malloc() with an argument of num * size. The exception is that the allocated memory is explicitly initialized to zero bytes. If num or size is 0, then memkind_call...
After the function call, the updated value ofnumis printed, demonstrating how the function effectively alters the value of the variable through pointer manipulation. Dynamic Memory Allocation The¬ation is fundamental when working with dynamic memory allocation using functions likemallocandcalloc. These ...
