can "endl" be changed to end line twice?

[Zhuge]

ran an older dos compiler. goes back a ways.

What are you saying? Your first two sentences are borderline nonsensical.

And what is the point of the second line? Are you surprised that the given statement works?

int o = 20; // global before int main() does work

[1CfG1hU5]

could you quote when you post?

[Zhuge]

As you requested.

[1CfG1hU5]

doubted "int o = 20;" before main would work. that is correct.

why are you asking about a proof done and agreed to. that the integer definition does work.

go find something else to do.

[Zhuge]

I'm not asking about the fact that the given statement works. I'm trying to understand your point.

[1CfG1hU5]

#define doesn't use a ;
doubted an int could be declared before main

[Zhuge]

#define is not a statement read by the compiler as it is a preprocessor directive. This differs from declaring a global variable, which is a compiled statement. Each follows their own syntax.

I'm not certain how you took this to imply that you couldn't declare an integer before main, but as I suppose you have noticed it is certainly possible.

[1CfG1hU5]

whatever a #define is called, someone posted don't use a ";" with #define or #defines.
and I did not believe that integers could be defined above main. i now know differently.
i did not imply nondeclaration of integers before main. i now know i can. your argument
is tiring, this is distant from the topic, and i am very tired.
