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.
