and what would that look for "signed" big-endian?

Learn ways how signed numbers can be represented in memory

#include<bits/stdc++.h>
using namespace std;
struct p{
int x : 1;
int y : 2;
};
int main(){
struct p a;
cout<<a.x<<" "<<a.y<<endl;
return 0;
}

Output : -1 0

❓what does int x : 1 do?
Anonymous
It says unsigned int flag : 1; makes "flag as a one bit field"
Anonymous
so it means flag can either be 0 or 1. Right?
Jussi
yes. its size will be 1 bit.
Anonymous
but what would then be its default value?
Jussi
it is not defined
Anonymous
I mean what is struct_object.flag equals to?
Anonymous
so in my case int x : 1 means x is one bit field.
Anonymous
Then why did a.x give -1?
Anonymous
how does a.x appears in memory?

for int x:2; what happens to rest 2 bytes?
Mat
Jussi
how does a.x appears in memory?
most likely it will be a 32/64bit registry, but the software only reads first of it

What's stdc++.h?
a header file that includes every standard library, its good to use in programming contests
Mat
Oh right, now i remember it...
឵
dont use it every where
Anonymous
and the reason why a.x gives -1?
Anonymous
a.x -1 ??

Hi I am a student

Thanks
Ravan
I want to learn new things in c++
Ravan
Can u help me

Google can

cout<<"what ""
Ahmed
cout<<"Hello word!";
Ahmed
yeah . Just type namespace std;
I_Interface
std::cout
or "using std::cout" in code block
Shashank
Ahmed
Depends on VS or workshop you use for programming c++
Dima
this is bad
Dima
use std:: namespaces directly
I_Interface
use std:: namespaces directly
"using std::cout" in code block is also bad ? :(
Dima
Yeah I don’t think cout name is used much in other libs
Anonymous
If it declared in small scope it's just fine
Anonymous
Of course, if there is no name ambiguity
Anonymous
Am I wrong?
Ahmed
what's a bad idea in that namespace ? A memory leak or a problem would occur in the compiler?
Dima
Dima
wait.. is it a serious question?
I_Interface
what's a bad idea in that namespace ? A memory leak or a problem would occur in the compiler?
If using this namespace, it could make a conflict with functions from other libraries

Guys, could someone help me to use libraries? I don't understand how to use it

Observe the following block of code and determine what happens when x=2?
switch (x) {
case 1:
case 2:
case 3:cout<<"x is 3, so jumping to third branch"; goto thirdBranch;
Default:
cout<<"x is not within the range, so need to say Thank You! ";
}
Neutronix
Doesn't work #include <directory/namefile>
Dima
What the hell
Dima
just post the code
Neutronix
just post the code
It's not only 1 file, this library is 8 different files and they are connected
Mat

Can you do a proper question instead of posting some homework-style questions?

#howtoask
Neutronix
If I put the directory in one of these after the error is in another one etc
klimi
We cant use telepathy
Neutronix
I take the error also in the library, so i Think who made the libraries is not stupid and there's another system to do it
