    Question what is a referencing to?

    Code:
    
    #include <stdio.h>
    
    int main(void) {
      int *a;
      {
        int b = 5;
        a = &b;
      }
      return 0;
    }
    


    since b goes out of scope, would a be referencing to garbage?

    Yes, assuming the compiler doesn't optimize everything away.
