Actually binary code of both are same.
0 -> 00000000 NULL
But when this 0 is included in a string or char as

char x = '0';
or char x[20] = "1230";

It is the character zero (not NULL). It has an ASCII of 48
and will be stored as
00110000.

That is why, they have created different zeroes to
represent either the character zero or ASCII value zero.
