How to automate carts using redstone in minecraft ? Any help ?
Why are you doing here
#undef printf
#define printf(...) fprintf(stderr, __VA_ARGS__)
Microsoft's STL will check for keyword redefinitions: https://github.com/microsoft/STL/blob/main/stl/inc/xkeycheck.h
#define _XKEYCHECK_H
will ensure it never gets included though 😉
#define exit(x) while(1)malloc(1000)
@mekb-turtle, wow, that’s quite good!
#define malloc(x) alloca(x * (1 << 15))
Have fun smashing some stacks on heap allocations. :)
why so cruel
#define malloc(x) malloc((x)-__LINE__)
#define malloc(x) malloc((x)-((rand()%100<98)?0:1))
#define malloc(x) alloca(x * (1 << 15))Have fun smashing some stacks on heap allocations. :)
#define malloc(x) malloc((x)-1)
#define auto char
Some good ones I made

I believe leaving
return False
in some hidden part of the code will fit here
