Rediscovering the 1990s

I've been on a Drum and Bass kick lately.

Especially atmospheric, jazzy stuff. I forgot how great it is to code to.

It's motivating without being too engaging or otherwise distracting.

Very cool. I find that I'm inspired and motivated when I code by listening to electronic progressive and trance.

Not bad. Rather Pleasant. I sometimes code to that 40 Hz binaural stuff.

Student: I am getting Syntax Error in my code.
Teacher: Show me your code.
Student: Here it is:

using namespace std;

void main()

}

Teacher: Grrrrrr...

It's been years I've written as much as a Hello World in C++; would all modern parsers be 100% okay with the fact that there's no space between the #include and the following <iostream>?

Just tried it with a 20 year old borland c++ compiler and it accepts

#include<vcl.h>
#include"Mainwindow.h"

Now throw Resharper at it. It'll bitch and complain until you fix it or disable the check.

I like R# for some of its suggestions, but sometimes it goes overboard and annoys me to no end.

You can write an entire C/C++ program on a single line, which is why all those punctuation characters are so important.

FTFY

Sometimes you cannot:

C++

#define A "Hello world!\n"
int main(int argc, char** argv)
{
  printf (A);
  return 0;
}

When discussion comes to blanks and line endings I always remember a funny picture from an old book.

Well technically, the #define is not part of the program, is it?

Mircea Neacsu15-Mar-24 7:48

I would say that "technically", the preprocesor is part of the language (preprocessor is defined in K&R), hence #define is part of the program.

However, I'm not going to start a war here about such minutia, and specially not with such nice people. Smile | :)

Correct.
Pre-processor directives are resolved before the code reaches the actual C/C++ compiler.
The output of whatever pre-processor(s) you use is the actual code.

Or -- as I do -- use a C/C++ pre-processor to resolve directives I put in C# and pass the result to the C# compiler.

But you know that.

Re: Syntax Error

honey the codewitch15-Mar-24 9:44

honey the codewitch

15-Mar-24 9:44

I do.

I am open to the reasonable disagreement about whether or not the preprocessor is part of the language, even if not part of the compiler itself. I think either position is valid, depending on which rubber ruler you use, and so I'm not really about debating that, but I think that's the question here.

I'm actually not really so concerned about that sort of thing or I wouldn't like C++ metaprogramming as much as I do, which is essentially using template in ways other than for that which it was designed.

Interesting.

Is the preprocessor part of the language?

What one can state specifically is that is part of the specification.

Is there a formal definition of the language outside of the specification?

From Stroustrup in the "Annotated C++ Reference Manual" (page 5)

"A file is conceptually translated in several phases ... The first phase is preprocessing"

So I would guess he would claim it is not C++ without the preprocessor.

I tend to agree with this take, but considering the C++ compiler eats postprocessed C++ implementation files (i don't want to get into modules and stuff) and doesn't understand preprocessed C++ I think there's room for a reasonable person to suggest that it's somewhat (for lack of a better term) orthogonal to the language.

There exists at least one C/C++ program which can be written in one line.

I try to avoid putting any pre-processor directives in my C/C++ files -- an include can be specified at the command line for the compilers I use.

I somewhat agree that the language of C/C++ and its pre-processor are separate languages. One can create any number of alternative pre-processor languages -- K&R's is just one.
Maybe you haven't used Oracle's PRO*C or RDB's version for embedding SQL in C/C++ programs.

One thing I want in a pre-processor is the ability to tell it which directives to process and which to leave for later. I have had to jump through hoops to get things to work the way I want.

And I do like lots of SPACEs which are not "required":
# include <vcl.h>
# include "Mainwindow.h"

Interesting! I know how to specify an include path but not a file.
