There is also a -- operator for autodecrement.
#include<stdio.h> int main(){ char * s, * t ; s = "I'm melting!" ; while ( *(t=s++) ) { while ( *t ) printf("%c",*t++) ; printf("\n") ; } }This program prints sequence of shorter and shorter strings. In it we have used some very C-like notations. What best describes the action of
*(t=s++)
?

#:
Assign s to t then increment them both.
Dereference there common value, so it is a character,
check this character for zero (the end of string marker).
#:
Assign s to t, then replace old s by s plus 1. This moves to the
next character in the string. Dereference t, it is a character, check
this character for zero (the end of string marker).
#:
Increment the character referenced by s, assign the reference s to
t. Check if we are out of memory. If not, continue.

This program hasn't a prayer of working.
