Difference between malloc() and calloc() function

Explain the difference between malloc() and calloc() function.

Both functions are used to dynamically allocate the memory. The difference is that calloc initializes the allocated memory to 0 or Null while malloc contains garbage values.

The following are the differences between malloc() and calloc():

- Byte of memory is allocated by malloc(), whereas block of memory is allocated by calloc().

- malloc() takes a single argument, the size of memory, where as calloc takes two parameters, the number of variables to allocate memory and size of bytes of a single variable

- Memory initialization is not performed by malloc() , whereas memory is initialized by calloc().

- malloc(s) returns a pointer with enough storage with s bytes, where as calloc(n,s) returns a pointer with enough contiguous storage each with s bytes.
