And what does it mean there? (automatic storage duration)

  Do you mean automatic type deduction? Edit : I know it’s also storage specifier but it also does type deduction here, hope I’m not confused with the terminology

    It doesn't do type deduction there. In original C you could declare variables without a type, and these variables with auto have no type. So this "auto" is essentially saying "this variable without a type uses automatic storage". That's a completely different language feature from "deduce the type of this variable".

      Thanks.

      A variable without a type is 'int' so ```auto xx;``` means an int on the function local variable stack.

    No, it doesn't do type deduction. Without specifying the type, it assumes a type of int. Everything in C revolves around ints.

    here it means automatic storage duration

  It means it lives on the stack, so it "exists" until the function returns.

    That is true, but more nuanced. https://www.tutorialspoint.com/cprogramming/c_storage_classes.htm https://www.tutorialspoint.com/cprogramming/c_storage_classe...
