In this HackerRank class problem in c++ programming language, You have to create a class, named Student, representing the student's details, as mentioned above, and store the data of a student. Create setter and getter functions for each element; that is, the class should at least have the following functions:
- get_age, set_age
- get_first_name, set_first_name
- get_last_name, set_last_name
- get_standard, set_standard
Also, you have to create another method to_string() which returns the string consisting of the above elements, separated by a comma(,).
HackerRank Class problem solution in c++ programming.
#include <iostream> #include <sstream> using namespace std; class Student{ int age; int standard; string first_name; string last_name; public: Student() { age = 0; standard = 0; first_name.clear(); last_name.clear(); } void set_age(int newAge) { age = newAge; } void set_standard(int newStandard) { standard = newStandard; } void set_first_name(string newFirst_name) { first_name = newFirst_name; } void set_last_name(string newLast_name) { last_name = newLast_name; } int get_age() {return age;} int get_standard() {return standard;} string get_first_name() {return first_name;} string get_last_name() {return last_name;} string to_string() { stringstream ss; char c = ','; ss << age << c << first_name << c << last_name << c << standard; return ss.str(); } }; int main() { int age, standard; string first_name, last_name; cin >> age >> first_name >> last_name >> standard; Student st; st.set_age(age); st.set_standard(standard); st.set_first_name(first_name); st.set_last_name(last_name); cout << st.get_age() << "\n"; cout << st.get_last_name() << ", " << st.get_first_name() << "\n"; cout << st.get_standard() << "\n"; cout << "\n"; cout << st.to_string(); return 0; }
Second solution
#include <iostream> #include <sstream> using namespace std; /* Enter code for class Student here. Read statement for specification. */ class Student{ public: int age, standard; string first_name, last_name; void set_age(int a){ age = a; } void set_first_name(string a){ first_name = a; } void set_last_name(string a){ last_name = a; } void set_standard(int a){ standard = a; } int get_age(){ return age; } string get_first_name(){ return first_name; } string get_last_name(){ return last_name; } int get_standard(){ return standard; } string t_string(){ string s = ""; s+=to_string(age); s+=","; s+=first_name; s+=","; s+=last_name; s+=","; s+=to_string(standard); return s; } }; int main() { int age, standard; string first_name, last_name; cin >> age >> first_name >> last_name >> standard; Student st; st.set_age(age); st.set_standard(standard); st.set_first_name(first_name); st.set_last_name(last_name); cout << st.get_age() << "\n"; cout << st.get_last_name() << ", " << st.get_first_name() << "\n"; cout << st.get_standard() << "\n"; cout << "\n"; cout << st.t_string(); return 0; }
