struct Person {         

      string FirstName;

      string LastName;

};



class Builder {   

   public:      

   Person Builder::Build() {

      Person person;

      person.FirstName = "FirstName";

      person.LastName = "LastName";

      return person;   

   };  

};

When I compile this it gives me the below error:

'return' - structure have objects and cannot be copied.

I just need to create a struct or class object and return it, I don't want to do any copying.

I tried using & and * combinations but didn't work. I tried with a class instead of struct and it didn't work either.

I also tried with class as shown below:

class Person {   

   public:      

      string FirstName;

      string LastName;

};



class Builder {   

   public:      

   Person* Build() {

      Person person;

      person.FirstName = "FirstName";

      person.LastName = "LastName";

      return &person;   

   };  

};

int OnInit()

  {  



   Builder builder;

   Person* person = builder.Build();

   string firstName = person.FirstName;

   return(INIT_SUCCEEDED);

  }

And it gives me invalid pointer access when accessing person.FirstName in the OnInit() method at runtime.

Found the answer but how to avoid memory leak? how to destruct the object and its pointer after use?

class cPerson {   

      public:      

         string FirstName;

         string LastName;

   };



   class cBuilder {   

      public:      

      cPerson* Build() {

         cPerson* person = new cPerson();

         person.FirstName = "firstname";

         return person;   

      };  

   };

cBuilder builder;

   cPerson* person = builder.Build();

   string age = person.FirstName;

You can delete the object by delete(person); and if you are unsure the object is not a null, it is better to check if(CheckPointer(object)==POINTER_DYNAMIC)delete(object);

Overall you should have all such objects as variables with corresponding variable names, or keep them all in a collection and destroy the whole collection at end. You may also create global variable of object (before OnInit, not inside any function) and it is to be deleted at end of program.

Regarding the initial question - you cannot have string inside a struct, only primitives
