Thread: && - and

I wonder something for the operator: &&

My question here is if it is possible to declare that if you write for example the word: and
in the C++ code, this will meen: &&


As for example when you declare something like this:
int Number = 2;

This meens when you write: Number, what you actually is writing is: 2

Do you mean like this:

Code:

std::string AND ="&&";

?

Alternatively you could do this.

Code:

#define AND &&

But why exactly are you trying to achieve this? What is the point?

C++ should already allow you to use words instead of logical symbols (because not all keyboards have them). If your keyboard has those symbols, it might be better style to use them, though.

Check out here.

Your second question is not clear. You could do

Code:

#define Number 2

or define an int constant Number that has the value 2 (preferred).

Yes this was what I was after, this function do work for this purpose:

#define AND &&

AND will have the same meening as && but just for a specific area in the code.
Why I wanted to do this is because I will construct an own more "simplier" code language for easyuse so other people more easy can relate to the word "and" instead of &&.
This "simplier" code language is for scanning .txt files in a specific way...

I agree, there is no gain whatsoever to this and coders may be confused because there is no keyword AND.

With all due respect, if someone don't know how to program, they shouldn't be browsing the source.
It's up to you to define things, of course, but in general I don't recommend it.

Don't expect to many people to adopt this extension, though.

With defines you can change the syntax of C++ to resemble other "simpler" languages, but such attempts generally result in WTF. Someone who learns your extension will be rather helpless if they need to switch to standard C++.

Assuming descriptive variable names, AND and OR just add visual distraction IMO - or the statements using these operators are too complex anyway. In addition it won't help non-English programmers.

And instead of defining upper-case versions, did you check out my link which says that "and" and others are already built-in synonyms in C++.

Code:

#include <iostream>

#define WHILE(x) while(x) {
#define WEND }
#define PRINT(x) std::cout << x;

int main()
{
    int i = 1;
    WHILE(i != 10)
        PRINT(i)
        PRINT(" ")
        ++i;
    WEND
}

The point is that if you find C++ notation too confusing, but are rather happy about BASIC notation, for example, then rather than trying to turn C++ into BASIC you might better start coding in BASIC instead.

Aye, anon mentioned this twice.

I haven't actually seen anyone use those keywords.

My keyboard lay-out, for example, doesn't have a key for ^. Fortunately I need it seldom, but when I do, I rather type Alt + 094 than use bit_xor. With Code::Blocks even the Alt combination doesn't seem to work (?), so I resort to using the clipboard.

If someone were programming on a keyboard that doesn't have any of these symbols, I'd understand the usage of synonyms.

Well, even if there's no such char, I'm sure there's a way to type it without using Alt+XXXX? It exists on most keyboards so far as I'm aware.
