Some questions about functions with a class type

Question

So I am using C++ and experimenting with classes. I am trying to create a function with a class type. Here is the code:

struct action{
void setup(std::string){
/*...*/
}
};
action move(){
setup("*");//<-error:[use of undeclared identifier 'setup']
}

Can the instance function of the class access its member functions and objects? Also, what should it return? Do i have to create a seperate action instance to return? Can it be related to the action move ?Thanks!

Answer 1

For starters the function setup is a non-static member function of the class action . It can be used applied to an object of the class. And the function move returns nothing though it has the return type action .

The function move can look like

action move()
{
    action a;

    a.setup("*");

    return a;
}
