Solution
The true statement regarding calloc is: "It can allocate memory of any type and number".
Here's why:
-
"It only allocates memory for integers" - This is false. calloc can allocate memory for any data type, not just integers.
-
"It does not require the free function to deallocate memory" - This is also false. Just like malloc, memory allocated by calloc needs to be deallocated using the free function to avoid memory leaks.
-
"It can allocate memory of any type and number" - This is true. calloc stands for 'contiguous allocation'. The main difference between malloc and calloc is that calloc initializes the allocated memory to zero. You can specify the number of elements you want to allocate and the size of each element.
-
"It always allocates a fixed size of memory" - This is false. The amount of memory calloc allocates depends on the parameters you pass to it. You can allocate as much or as little memory as you need.
