but it seems uncommon,why you want to know?
Dream it
when we print %%%% , then why ouput is only %% ?
Dream it
can you explain
olli
cplusplus.com says
A % followed by another % character will write a single % to the stream.
olli
This makes perfect sense, since % has a special meaning in the format specifier. To actually print the symbol and not treat it as "format specifier" you need to escape it.
olli
This is basically the same when you want to print a backslash (\). Since the backslash is part of white space characters such as line feed or tabs, you need to escape it.

oh,im almost understand ,but what does % mean in C ?

Its means modulo

Have you printed a number using printf before?

Ie when u divide any number and the remainder you get is answer

yes
olli
Exactly!. But now imagine you actually want to print "%d", how would the printf function Know what you want?

Wdyt about Google code jam vs Facebook hacker cup?
olli
i dont know ,sorry
No worries - kind a rhetorical question
Since "%d" means an integer, you need to write "%%d". The first % starts a "format", but since you don't want to have one you tell it just to write the symbol "%" by adding a second "%". (Similar to \\ printing \)

the only problem is when I type anything else than 'y' or 'n' and longer than single word at the end (when it asks me go again y/n ?) it gives twice 'your answer is not correct' it because of the type of 'answer' is char and I cant change it to string when I change it gives an error : need your help guys

printf("%%%%\n");

Oh; ez. As you know % is used for giving it parameters like %d %f etc. Consider you want to print % to the output, in C to do this , you type %% this puts one % to output

Hey, I have a problem with two functions in C. Is it allowed to send code here or better use pastebin?

how to master the language c

I am in trouble
Sid Sun
I do basics of technology I'm interested in
Sid Sun
Then I think of any project that gets be interested and do it using that technology

Some are absurd

But I like to work on them because I do things to learn :)

can you teach me, because I want to be serious about learning to master C, because this is very important for my department

okey, first i dont know how to use looping
Anonymous
this makes me dizzy
Sid Sun
i dont know,what are its main uses?
Okay.
Loops are used when we need to do something in a pattern or do something over and over again.
For example: Print hello 5 times.
You can do it using printf 5 times but that is not ideal since that way you are doing hardcode, you can instead use loops and print 5 times or, as many times as the user wants without touching your code!

I know I'm starting to understand, but what code is used if it's not 'printf'?

can anyone recommend some books to read for us new?
Sid Sun

we can use for loop to solve that problem like this:
for (i=0;i<5;i++) {
printf("hello");
}

do we add (int i;) to for (i = 0; i <5; i ++)?
Anonymous
wow,thank you!
Sid Sun

Yes,
We obviously need to declare the variable we are going to use
Sid Sun
What this does:
set the variable 'i' as 0
Then check if i is less than 5 (it is 0, so yes)
It runs printf and prints 'hello'
it increases the value of 'i' by 1
Then it checks again and if condition is (note that i is set as 0 only the first time, after that it is not executed) true, it prints 'hello'
It increases it by 1 again

but do you use software / applications for coding like C?
