calloc

`calloc` is a function in programming, specifically in C and C++, that allocates memory for an array of elements. It stands out because it not only reserves space but also initializes all the allocated memory to zero. This is helpful for managing memory safely, as it reduces the chances of using uninitialized data. When you use `calloc`, you specify how many elements you need and the size of each element. The function then returns a pointer to the allocated memory, which can be used for storing data in a controlled way.
