what is wrong with this simple code?

[asdf]

Members defined in the private section are accessible to other class
members. So, I think the following is correct.

#include<iostream>
using namespace std;

class A{
int x;
public:
int get(x) {return 1;};
};

int main()
{
return 0;
}

However, there is a syntax error : identifier 'x'

what's the reason? the private member cannot be the parameter of the
public function?

I am a mere student so take what I say with a grain of salt.

I think get might be reserved, but if it isn't then you need to do:

int get(int x){return 1;}

and that should work.

I think you mean:

int get(int x) { return 1; }

In the above, x would be the type of the unnamed function argument.
However, x is not a type.

The compiler in this context is unable to establish a signature for the
member function. Any parameter specified must therefore have a type in
order to construct the signature. Remember that parameters are objects
from the outside world insofar as the instance of the class is
concerned. get(...) doesn't need to pass x as a parameter since it is
already part of the object.

int main()
{
return 0;
}

Presumably, your goal is to use get(...) to "get" x's value all you
need to do is return the private integer. In order to protect x from
being modified through side-effects, get() should be constant.

class A
{
int x;
public:
A(int n = 1) : x(n) { } // or A() : x(1) { }
int get() const { return x; }
};

And we haven't touched copy ctors nor assignment operators.

Is this what you meant?

class A{
int x;
public:
int get() { return x; };

Better still, make it

int get() const {return x;}
