can anyone tell me what's wrong in this

Maybe parentheses in conditions
Alsl idk if you can put few variables in cin

No that's working
Modern College
But it the compiler is saying that you need a ; before cout
Modern College
And if is needed before else

Its have a syntax error cin>>x>>y; and this is the part

Its have a syntax error cin>>x>>y; and this is the part
The cin just accept one variable

No there are two variables in the declaration part

Oh yes... sorry

And its a tricky question keep it up

Its have a syntax error cin>>x>>y; and this is the part
I get that and also corrected that but still there is error

It's say there is no if before else statement

Try the above code. This was already suggested by someone before.

No in my compiler it cheats 2 bit still that error
Means it accepts only one variable at a time
Modern College
#include<iostream>
using namespace std;
int main()
{
int x,y;
cout<<"Enter your numbers:";
cin>>x,y;
if(x>y){
cout<<"x is greter number";
cout<<"y is smaller number";
} else {
cout<<"y is greater number";
cout<<"x is smaller number";
}
return 0;
}
Thank you soo much I was missing the curly bracket
Modern College
If you use cin>>a>>b>>c

Guys what is the use of STL(C++) Container in Data structures ?

The STL containers ARE the data structures.
Anonymous
What is the use assoctive container?
Anonymous
What is the use assoctive container?
To store key value pairs or in the case of sets to store keys alone

Which container used to create tree?

Okay thank you ma'am

add |= (1ll <<j)
Came across this
What does this "|=" mean?
Anonymous
operator after add

add |= (1ll <<j)

What does this "|=" mean?
Bitwise or operation

oh lol yes sorry my bad
it ORs with the value present in add

data should not be immutable if it is inside of a [&] capture right?

No. That applies to only value captures.
Anonymous
so it is immutable inside of a [&] capture?
Anonymous

If it is captured by reference it is mutable. Only by value captures are immutable. You have to use the mutable keyword to make them mutable inside the lambda
Anonymous
hmmm ok
Anonymous
well somehow my variables are immutable ;-;
Anonymous
it is a bit complex
Anonymous
it is a bit complex
Then I guess you must have made a mistake somewhere. Are you getting compiler errors when you try to mutate the reference inside the lambda body?

that is my code

It is a bit difficult to work with that. Usually in forums like these what helps is an MVCE.

yea
Anonymous
how about this instead?
Anonymous
as physicsTimeStep is 0 anyway
Anonymous

Where do you get the error? Is it at the get call inside the lambda body. The name get doesnt suggest it is a mutating call btw. Is it a const method?
Anonymous
however, oddly if i change the timestep to 0.25/60.0 then my object becomes mutable
Anonymous
but i am not sure why it becomes immutable when timestep is 0

#include <iostream>

int a = 10;
auto func = [&]{++a;};
func();
cout << a << endl;
}
Reference captures are mutable as this example shows. I am not sure what is wrong with your code with just the data ou have given. So guess you will have to debug it yourself.

Hi! I am a beginner. I wanted to ask where you learnt c++ from? How to practice?

From books just like everyone else and also at work. If you want to learn about C++ follow the books mentioned in the pinned thread (the stackoverflow link) and thereafter it is just practice that makes you better....you can practice by picking up some easy C++ code bases on github like log4cpp and so on and make changes....

Any one knows basics of OOP I have a project and I make the classes and everything and It was working so good till I tried to separate a cpp class into . h and . Cpp files

I see the constructor is defined in the cpp file. Not sure why the linker is complaining. I am not near a system right now. I will check it when I am nea one. Should be a simple issue.
