Ok

That's why it better to use for loops instead of while in such cases, more difficult to forget such things and looks better

Hi guys! I have problem with reading these loops: int h = 125; while (h > 0) h—; How many times will it repeat? What about that: int h = 125; while (h— > 0) ; And that: int h = 125; while (—h > 0) h; And that: int h = 125; while (—h >= 0) h—; Am I stupid, or there is some trick to read it and predict how many times it will repeat? C is a simple language, “you get what you write”, but why I don’t understand what will I have in situations I described. Pls can you give me some advice

U know pre increment and post increment right?

Yes of course

Then u don't need any trick

--h>0 or --h>=0?

So, in every iteration of the loop, the value of h reduces by 2, so as h equals 25, u've had 50 iterations, and again when h=1, u've had 12 more iterations, then --h gives 0 which isn't>0 so, u've 62 iterations of the loop

Ok, I think I understood this, but I will think about it. How many years have you been practicing?

I've studied C just months back

In the last year I've learnt basics of Python and C

it's fair to call any language a nightmare

I do not know why all over the internet Python is considered an angel and C ++ is a nightmare and a useless language. These words are funny, but on the other hand, they torment me

Nicely said Although I think that's because of the many Python libraries As well as the famous phrase "suitable for hacking" But I prefer this advantage of C++ to any other advantage: speed It's true,in C++ we often need to reinvent the wheel But I also like this

In my opinion, one of the main issues is the simplicity of the Python language. I know a lot of YouTubers who say that C ++ is not worth learning, C ++ is insanely hard. They talk about C ++ without any knowledge and encourage beginners to stay away from C ++

Hey, I am a beginner in C I had written program of calculating total marks, but the Output of total marks in value is showing large no in negative ex: Totalmarks:-9036284, Totalmarls:-3768992

Without code nobody can help.

Hey guys i just wanted to know whether there is any pro coder in C ?

Yes Maybe one of the reasons is the lack of jobs Although I do not know the situation in your country

The truth is that the web world and the C # language are popular in my country (although I'm not interested in the web world) But my goal in learning C ++ is to make games.

good,gams👌 When I wanted to choose a language to learn, Someone suggested me C#, because you can build graphic software from scratch. But I had no interest in it I was strangely in love with C++, then he told me: In C++ you go back to the DOS environment, boring and harsh, but it was strangely sweet to me, although after a few months of programming, I was very disappointed😂 And I quit programming for two years, but now I'm on my way back to C++😄 where are you from?🤔

Why the DOS environment?

cmd like DOS

Honestly, like you, I'm particularly interested in C ++ I do not know why, we have simpler languages ​​but C ++ is fun for me and I use sfml to make the game, working with sfml is like Dark Souls game Hard but enjoyable. I'm from Iran

oh you mean cli? okay c:

hey, i'm trying to loop over a user input using while loop (the input is for example "1 2 3 4 5") i want to append the integers into array, how do i do it ? this is what i wrote so far.. but something is obviously wrong with it printf("\nInsert the first vector : \n"); while (scanf(" %d", u)==1) { scanf("%d", u[i]); }

doesn't scanf take whole line as an input?

This will read subsequent characters until a whitespace is found (whitespace characters are considered to be blank, newline and tab)

why can't we use float main() in a c program?

For what

i was using float main() for calling my main function but my ide showed warning

i was using float main() for calling my main function but my ide showed warning

Because you need to use int

does this make sense? what i want is to set a default value when i call my function int function(int a, int b, int c=0){ statements }

does this make sense? what i want is to set a default value when i call my function int function(int a, int b, int c=0){ statements }

why is it so?

Yes, you can do that, you can also make a function overload that calls the function with three arguments passing the default value to the third one. Both have pros and cons

because all programs should return int value (return code) which means how program was end. 0 - all okey, != 0 - error

also you shouldnt

I confused about this: inline void f(void) { printf(“I am inline func\n”); } #define f2(…) printf(“I am macro\n”); As I read on forums the meaning of inline keyword is that it’s used for telling compiler to paste function code into place where it was called. But macro do the same, only one difference I saw - macro code pasted by preprocessor, and inline function pasted by compiler. Then - what difference between these two, can someone explain better pls.

Whos know why on arch linux i can write g++ values like i want: g++ -lSDL2 -lSDL2_images -lMyLib main.cpp And on debian i need to put main.cpp first, then my shared lib and then sdl2? g++ main.cpp -lMyLib -lSDL2 -lSDL2_images Otherwise linker error: undefined reference

strange because that'd only work if the implementation is different

I found answer on stackoverflow about g++ order of values are important, but on my arch its not necessary, idk why
