The if statement uses {} not (), btw

And I will replace 0 to 1 then what happen

Correct way is to use a !

And I will 1 then

'Cause one might think !strcmp() means non equality

I'm the function of strcmp

No

I get a compile error using: if (cond) ( // )

Yeah, I know. I meant the () need to be {}

But which ()?

Also shouldn't if()() work for a single line?

Didnt compile for me

I guess you could do this :P if(cond) (void) ( // );

Does not look like a valid syntax

https://godbolt.org/z/aKToMe It works :P

Well it's a weird syntax

Put ";" instead of ") "

if (a == b) (void) (printf("a"));

How does that even work, just by casting the following to a void type? Like is it even a conditional statement then?

casting to void turns the expression into a void expression, suppressing any warnings. for example - you can use that with printf(), which returns the number of characters printed, when warn on unused return value is enabled. omitting that, the snippet becomes - if (a == b) (printf("a")); the parentheses are superfluous. and so - if (a == b) printf("a");

So now help me guys I need tips on how to build a data compression algorithm

The new keyword is only for C++, not C right?

Why not using an existing one? LZMA is pretty good

Coz I have one that will work better than that one.. I have the mathematics (I'm working on a special thesis on an unestablished branch of mathematical and its best demonstrated in data compression.. I have the algorithm but I just don't know where to start in coding it yet)

You're asking "how to build data compression algorithm". It seems that you don't have one yet. Building new compression algorithms is not related to C/C++ group. You need to have one before starting coding anything

Here is the lib: (the first code sample is where I can't continue) https://github.com/berndporr/kiss-fft

Why are using both "free" and "delete" ? You should never use both. If you're using C++ use delete/new only, if you use C use malloc /free only. Don't mix them together

I repeat I already have an entire paper I'm soon to publish on the methods and steps that need to be used if you need to code for one... So far it's in charts, equations and words... I want to turn it to code preferably C++ that's why I asked for tips

++. Free on memory allocated via new is UB.

What tips do you want? If you have an algorithm go and implement it. Show in what way your algorithm is better. Is performance? Is it compression? Who knows what your algorithm does except you? 🤷‍♂️

Igor if you ain't going to help its better you ignore me coz you are being rude right now... I get the fact that you feel you are a super master coder and anyone whose is not at your level is trash.. Nice attitude bud... I guess that's why you are a muti millionaire / billionaire rn 😊
