name = new char[strlen(temp.name) + 1];
new的是数组,要用[]class study { public: char* name, * url; public: study(const char* name, const char* url) { this->name = new char[strlen(name) + 1]; this->url = new char[strlen(url) + 1]; if (this->name) strcpy(this->name, name); if (this->url) strcpy(this->url, url); } study(study& temp) { name = new char[strlen(temp.name) + 1]; url = new char[strlen(temp.url) + 1]; if (name) strcpy(name, temp.name); if (url) strcpy(url, temp.url); } study& operator =(study& temp) { delete[] name; delete[] url; name = new char[strlen(temp.name) + 1]; url = new char[strlen(temp.url) + 1]; if (name) strcpy(name, temp.name); if (url) strcpy(url, temp.url); return *this; } }; int main() { study a("试试", "www.shishi.com"); cout << a.name << ":" << a.url << endl; study b = a; cout << b.name << ":" << b.url << endl; study c("看看", "www.kankan.com"); b = c; cout << b.name << ":" << b.url << endl; system("pause"); return 0; }
