The two functions mainly is to allocate memory and they are commonly called as memory managers.
Malloc() :- Malloc function take one argument
Calloc() :- Calloc function take two argument in a time. The bits in the allocated space are initialized to zero.
Both malloc ans calloc are used in C language for dynamic memory allocation they obtain blocks of memory dynamically.
But there are two main differences between malloc and calloc in C programming language;
- the number of arguments. The malloc takes a single argument and calloc takes two.
- malloc does not initialize the memory allocated and calloc initializes the allocated memory to 0.
