S.K it's very similar to other data types : #include <iostream> using namespace std; class student { string name; public : void setname(string str){name = str;} }; int main() { student s[3]; s[0].setname("Ketan"); return 0; }

S.K refer below : #include <iostream> using namespace std; class student { string name; public : student(string str){name = str;} }; int main() { student s[3] = {student("Ketan"),student("Ketan1"),student("Ketan2")}; return 0; } let me know if you want something else

seems it is incomplete code and you are unable to paste entire due to size limit... please copy link of code and paste it here to have a look into it

Please help me figure out this problem. I enter data for 3 laptops and loop prints data of the last laptop only for 3 times. #include <iostream> #include <string> using namespace std; class laptop { private: string brand; string model; int serial; string color; float price; float processor_Speed; int ram; float screen_Size; public: void display() { cout<<"Brand: "<<brand<<endl; cout<<"Model: "<<model<<endl; cout<<"Serial No. "<<serial<<endl; cout<<"Color: "<<color<<endl; cout<<"Price: "<<price<<endl; cout<<"Processor Speed: "<<processor_Speed<<endl; cout<<"RAM :"<<ram<<endl; cout<<"Screen Size: "<<screen_Size<<endl; cout<<"-------------------"<<endl; } laptop(string b, string m, int s, string c, float p, float ps,int r, float sz) { brand = b; model = m; serial = s; color = c; price = p; processor
