Deep Copy in C++: How to Avoid Shallow Copy Pitfalls
You must implement all three. This is called the Rule of Three.
class String {
private:
char* buffer;
public:
String(const char* str) {
buffer = new char[strlen(str) + 1];
strcpy(buffer, str);
}
// Copy constructor
String(const String& other) {
buffer = new char[strlen(other.buffer) + 1];
strcpy(buffer, other.buffer);
}
// Assignment operator
String& operator=(const String& other) {
if (this != &other) {
delete[] buffer;
buffer = new char[strlen(other.buffer) + 1];
strcpy(buffer, other.buffer);
}
return *this;
}
~String() {
delete[] buffer;
}
