c++ syntax of define member function that take in int and return pointer to in at outside of the class

Question

i have a problem in my c++ lab assignment ,i been searching google and i tried with this syntax and it won't show unqualified-Id compile error

typedef int (list::*find)(int val);
{
    return 0;
}

The declaration at header file

class list {
public:
int *find(int val);
}

what is the syntax of define a member function that take in int and return pointer to in at outside of the class?

There is never a semi-colon on a function definition before the `{`. Remove it. — bns, Feb 02 '18 at 12:48

This would be the correct syntax:

int* list::find(int val)
{
    // Implementation
}

The function declaration isn't that of a function pointer, which is what it seems you are trying to do, but a function that returns a pointer to an integer.

The general syntax of a member function defined outside a class is:

ReturnType Class::FunctionName([OptionalParameters]) [OptionalQualifiers]
{
    // Implementation
}

as you are trying to go for the general case you should also mention qualifiers (eg `const`) – 463035818_is_not_an_ai Feb 02 '18 at 13:03
