so point of program ask student first name, how many classes they're taking semester, , asks names of each of classes. problem can't classlist array work , display class names user in program output. i've marked think issue coming , think super easy fix i'm not seeing it. help?

i'm coding in microsoft visual studio 2013 way.

#include <iostream> #include <string>  using namespace std;  class student { public: //public class student      student(string first_name, string last_name, int num, string list);     student();       void input(); //input user     void output(); //output user depending on input       // accessors      const string get_name();     const int get_numclasses();     const string get_classlist();       // mutators     void set_name(string name);     void set_numclasses(int num);     void set_classlist(string list);   private:      string name;     int numclasses;     string classlist; };   // constructor's variable student::student()  {     name;     numclasses = 0;     classlist; }   // accessors called public class student string const student::get_name() {     return name; } int const student::get_numclasses() {     return numclasses; } string const student::get_classlist() {     return classlist; }   // mutators set public class student void student::set_name(string studentname) {     name = studentname; } void student::set_numclasses(int num) {     numclasses = num; } void student::set_classlist(string list) {     classlist = list; }   // accessors here void student::input() {     int x;      cout << "enter name (first name only): ";     cin >> name;     cin.ignore();     cout << "how many classes taking semester?: ";     cin >> numclasses;     cin.ignore();      if (numclasses> 0)     {         string* classlist = new std::string[numclasses]; // <--- error on line think         (x = 0; x<numclasses; x++) // loop classlist array         {             cout << "enter name of class " << (x + 1) << endl;             cin >> classlist[x]; // <--- or maybe error on line too?         }     }      cout << '\n' << endl; }   // displays output according user void student::output() {     cout << "students name: " << name << endl;     cout << "number of classes semester?: " << numclasses << endl;     cout << "displayed class list: " << classlist << endl; }  int main() {     char go_again = 'y';     while (go_again == 'y' || go_again == 'y')     {         student s1;         s1.input();          s1.output(); //output student          cout << "\nrestart new data? (press y/n) " << endl;         cin >> go_again;     }       if (go_again == 'n')     {         return 0;     }      system("pause");     return 0;  } 

your student class declares string named classlist, input() method declares new variable of type string*, named classlist. it's called shadowing, and, while legal, avoided, kind of problems seeing. unintended , confusing.
