I have seen people using following C++ syntax... if (var1 == var2) cout << "bla" << endl; cin > blub; Is that correct syntax?

Artöm

cin >> blub;, otherwise its correct I think

Ah.

I have seen people using following C++ syntax... if (var1 == var2) cout << "bla" << endl; cin > blub; Is that correct syntax?

When there is only a if, and not else if or else or there is only an instruction for the if, the curly brackets aren't necessary, the error is cin>>blub

Nils

Great thx

Nils

Has somebody an idea, what .s files are?

NXiss7

Assembly files.

NXiss7

.S files

Nils

Assembly files.

Okay, how do I compile them? 🤔

NXiss7

You don't 😄😄😄😁

Nils

Uhm, then how to run/execute them?

NXiss7

Where did you find it?

Nils

Where did you find it?

On a github repo

Hubert

you need link them instead of compile 😁

NXiss7

Uhm, then how to run/execute them?

You compile then link. I was joking.

Nils

I am confused 🤔

NXiss7

you need link them instead of compile 😁

Nope, it needs to compiled too into machine code, just one step closer. 😂

NXiss7

On a github repo

Send the link

Nils

Okay.

Nils

Just noticed it got deleted in a recent commit 😅

NXiss7

did you try to check the 6.1 file if it was exist after compile?

Anonymous

did you try to check the 6.1 file if it was exist after compile?

No. How?

Anonymous

In the target directory, I have a 6.1.c file, not a 6.1

Hubert

let check the output file after compile

Luca

try gcc 6.1.c -o 6.1 @imHubert

Hubert

try gcc 6.1.c -o 6.1 @imHubert

yes, command should like this

Nils

What is wrong with this: write(1, "hi\n", 3)?

I did not import unistd.h

Thanks. I used to compile programs by - g symbols to make it debuggable. Now it won't work. What am I to do?

You tell compiler to output to a file named "output" (by using -o). So your exe's name is "output".

Which are more efficient vectors or array?

NXiss7

Depends on needs

Anonymous

Why don't we just use vectors?

NXiss7

Raw C arrays are "thinner" of course.

NXiss7

Why don't we just use vectors?

You don't always need it

Anonymous

You don't always need it

Instead of array I means

NXiss7

std::array or C arrays?

Hi guys. what I need to do if my precompile header (pch.h) located upper my current file. if i write like this: #include "../pch.h" i am getting the error, due I not included this file. thanks

Luca

try moving your header file into your sorgent file directory than removing the / at the start when you include it in the code

Dima

try to explicitly specify header paths
