What is the output of the following program that compiles correctly? (Hint: When evaluating logical operators, the compiler ignores the remainder of the expression when it is sure of the final answer at any point of evaluation of the sub-expression - something often referred to as "short-circuit evaluation". This is a cryptic hint, I know, but enjoy unravelling it and discovering its meaning and implication!)

#include <stdio.h>

int main()
{
  int a= -2, b= -1, c = 0, d = 1, e = 2;
  int r1, r2;
  r2 = a++ || ++b || c++ || ++d || e;   
  r1 = a && b++ && ++c && d++ && ++e;  
  printf("%d %d %d\n", r1,r2,a+b+c+d+e);
  return 0;
}
