Wth is wrong with this code? I think my colons, semicolons and brackets are okay. How is 'idnumber' not declared in this scope?

Question

class id
{public:
id (int a)
{setidnumber(idn);}
void setidnumber(int x)
{idnumber = x; }
string getresidence()
{return residence;}
private:
string residence;};

int main()
{id ob1 ("1234");
id ob2 ("3456");
cout << ob1.getresidence();}

Answer 1

u need a private variable idnumber to store the id number (hehe) and on id constructor is setidnumber(a); not setidnumber(idn) couse idn isnt defined, also in main remember that anything within coutes are strings so "1234" is not an int.

Answer 2

Lol. Thanks, Hector. That was easy. Though it works with setidnumber(idn) too. Thank you.

Answer 3

luka, i don't code that way, though. i just put it that way to post here
