calloc is memory allocation function that is normally used for requesting memory space at run time 4 storing data types such as arrays and structures. calloc allocates multiple blocks of storage, each of the same size and then sets all bytes to zero, and then returns a pointer to the memory.
Use the free function to release memory that was previously allocated by malloc, calloc or realloc.
Sizeof is an example.
No.
The first part is true (malloc allocates a single block of storage) but the second part is not. Malloc is for allocating un-initialized memory. calloc initializes all bytes to 0.

Use the free function to release memory that was previously allocated by malloc, calloc or realloc.
There are no commands in C-programming, you should use function sqrt from math.h
the return type is void
free() is a function used to free the memory allocated dynamically ,by both malloc and calloc functions. free(ptr): ptr is a pointer to a memory block which has already been creeated by malloc or calloc.
Sizeof is an example.

it is sqrt in header math.h

'void *' (or 'char *' if your system is very old)
Sequential style, or function-oriented. Which is opposed to object-oriented, as in C++.
printf, fgets, strlen, malloc etc
