doubt
#include <stdio.h> int main(void) { static int a[10]; int x=0; a[x]=++x; printf("%d %d %d",a[0],a[1],a[2]); return 0; } my doubt here is [ ] has high precedence over ++ which in turn has precedence over =, so i think it a[x] = ++x; is evaluated in 3 ... > a* phase2: ++x -> x=1 phase3: a*=1 or a[0]=1 so finally answer should be 1 0 0, but it is giving 0 1 0 as output.

("%d",-(-5)); leading to no compiler error and giving answer as 5, but macro implicitly never put precedence braces() itself...
