While this is written in K & R "The scope of a name defined with #define is from its point of definition to the end of the source file being compiled."

Why this piece of code is working fine ?

...

Thanks for replying,

Can you tell me an example where a line is ended by ";" and that line is not called as statement ?

I have written this code



#include <stdio.h>

int main() {
unsigned char c;

Is every line terminated by ";" is a statement in C ?
Which type of statement is "int i;" ?
Is #include <stdio.h> is also a statement?

If my string s size is n and I do something like

s.resize(c); // c < n

will it take constant time or linear?

What will it be in case of c > n.

Thank you all guys :)

Thanks

If I write some thing like this

for(int i = 0 ; i < strlen(s) ; i++)

will it be O(n^2) ?

Also please tell me where can I see codes of standard library of C (GCC) in Ubuntu.

Is it true that is c99, a%b is calulated as sign(a) * (abs(a) % abs(b)) ?

where,
sign(a) = 1 if a is +ve
sign(a) = -1 if a is -ve.

I have written a code in a file 4.c



#incldue<stdio.h>

int main() {
printf("%d",fun(22));
return 0;
}

Hi,

Can anybody tell me whether compilation error given by a compiler are specific to it or Standard say something like "This behavior is an Error and it should be reported as Error on all...

Just confirming

is expression

i = i = 1;

also undefined because it also modifies the object more than once between sequence point

Is there any difference between these two terms.

Thanks

but can be larger than 8 bits(in both c89 and c99), right ?

What are limitations on size of char, are there any differences in c89 and c99 on size of char

I can understand that the size of



struct {
char c;
int x;
}

Thank you so much for clarifying my doubt:)

Actually K&R says that float has single-precision, what I want to know is that whether single-precision is attached with IEEE or not, AFAIK single precision term always comes with IEEE.

Please...

I was reading K&R, in section 2.2 they mentioned that

float is single precision floating point, and
double is double precision floating point

When I checked wiki, it says that "IEEE...

Thanks got it :)

Thanks you very much for such a clear answer :).

Regarding second question I think it should be well defined, because I have read this at many places that "++i" will "first increment the value of...

I was learning sequence point and I get really confused by example given in wikipedia that "i=i++" is undefined,

Can anybody explain me why it is so ? I can understand that "a[i] = i++" is...

Why C provides this '\?', when we can use plain '?' or "?" ?

Thanks :)
