What are the differences between malloc () and calloc ()?

Malloc Calloc 1-Malloc takes one argument Malloc(a);where a number of bytes 2-memory allocated contains garbage values

1-Calloc takes two arguments Calloc(b,c) where b no of object and c size of object

2-It initializes the contains of block of memory to zerosMalloc takes one argument, memory allocated contains garbage values.

It allocates contiguous memory locations. Calloc takes two arguments, memory allocated contains all zeros, and the memory allocated is not contiguous.

  1. calloc(…) allocates a block of memory for an array of elements of a certain size. By default the block is initialized to 0. The total number of memory allocated will be (number_of_elements * size).

    malloc(…) takes in only a single argument which is the memory required in bytes. malloc(…) allocated bytes of memory and not blocks of memory like calloc(…).

    1. malloc(…) allocates memory blocks and returns a void pointer to the allocated space, or NULL if there is insufficient memory available.

    calloc(…) allocates an array in memory with elements initialized to 0 and returns a pointer to the allocated space. calloc(…) calls malloc(…) in order to use the C++ _set_new_mode function to set the new handler mode.

There are 2 differences.
First, is in the number of arguments. malloc() takes a single argument(memory required in bytes), while calloc() needs 2
arguments(number of variables to allocate memory, size in bytes of a single variable).
Secondly, malloc() does not initialize the memory allocated, while calloc() initializes the allocated memory to ZERO.
