Bitwise Leftshift (<<) strange behavior

Question

gcc bitwise Leftshift (<<) strange behavior. Here is my code:

#include 
#include 

void foo(in         


        

Answer 1

I finally figure out a work-around solution, at least make the output identical.

#include 
#include 

void foo(int n){
  printf("1<<32:%d\n", 1<<32);
  printf("1<<(32-n):%d\n", (1<<(31-n))<<1);
}

int main(){
    foo(0);
}
