Malloc:
Malloc allocates memory but does not initialize it.
Example: char *szPtr = ( char* ) malloc( sizeof( char ) *
100 );
Here szPtr is assigned 100 bytes. But the memory is not
initialized. It contains garbage.

Calloc:
Allocates a block of memory for an array of 'n' elements,
each of them 'l' bytes long, and initializes all its bits
to zero.
Example: char *szPtr = ( char* ) calloc( 100, sizeof(
char ));
Here szPtr is assigned 100 bytes & the memory is
initialized to 0.
