8bit, you can't do that (can have only 1 return 0;)
Cse-icons you devil, who the hell would do that? Just playing around of course, I didn't get it. I'm too practical

void fun()
{ int i=0; while(true) i++; } overflow and program will end... or user will kill the program after waiting for a bit. -------------------------------- void fun() { int *i=0; while(true) *(i++)=i; } same as above plus there is a chance that program corrupts some critical data and crashes |

QUOTE(cse-icons @ Nov 17 2004, 03:07 AM) How do I manipulate and change the value of i? Technically you aren't changing the value of i -- you're defining a new i (it's at a new memory address). To answer your puzzle, you can change the value of i using an ASM injection attack using a noop sled to compensate for the variance in memory allocation addresses. |

QUOTE 8bit, you can't do that (can have only 1 return 0;) The reason why he can't do it is because the return type is void, but if it was int like this: int fun(void) { } then he can do it. |
