Is this legal ? C++

I have a simple question.. Can i allocate and deallocate memory like this in the operator+ for other object

delete [] p.name; p.name = new char[strlen(a.name) + 1];

Look at the operator+

class PlDrustvo{
private:
   char *name;
public:
// Constructors and destructors are implemented.

PlDrustvo operator+(const PlDrustvo &a)
{
    PlDrustvo p(*this);
    if(///////){
        delete [] p.name;
        p.name = new char[strlen(a.name) + 1];
        strcpy(p.name, a.name);
    }

    return p;
}

};

Yes, you can do that. However, it's better to use std::string instead of char*. If name were a std::string, you could just write p.name = a.name; and it would allocate memory and copy the data automatically.

(std::string also has an operator+ that does string concatenation, so you could join the two names by writing p.name = name + a.name; – I'm guessing that might be what you actually want your operator+ function to do.)
