Question

1. Given in part the str class interface below, implement the overloaded assignment operator class str public: str& operator (str &rhs); // Postcondition: contents of rhs (right-hand-side object) İs assigned to the calling object without memory leak private: int length; // # of characters of a C-string not including the NULL character "O' pointed to by p char *p; points to dynamic memory used to store sting of characters 1;

Answer 1

class str {
public:
    str& operator=(str &rhs);
private:
    int length;
    char *p;
};

str &str::operator=(str &rhs) {
    this->length = rhs.length;
    this->p = new char[this->length];
    for(int i = 0; i < this->length; ++i) {
        this->p[i] = rhs.p[i];
    }
    return *this;
}
