    expected primary -expression before '}' token }

    Code:
    #include <iostream>
    #include <fstream>
    #include "pass.h"
    
    
    using namespace std;

            char city[20];
            int admno;

        student s;

         while(ch=='Y' || ch=='y')

    Your default needs to actually do something, even if that something is nothing.

    Perhaps like this.
    Code:
    #include <iostream>
    #include <fstream>
    //#include "pass.h"
    
    using namespace std;
    
    class data {
    public:
      struct student {
        char name[20];
        int clas;
        char city[20];
        int admno;
      };
      student s;
      void add() {
        char ch = 'Y';
        ofstream outfile;
        outfile.open("STUDENT.DAT", ios::out | ios::binary);
        cout << endl << "Enter a record:name |  class | city |  admissionno\n";
        while (ch == 'Y' || ch == 'y') {
          cin >> s.name >> s.clas >> s.city >> s.admno;
          outfile.write((char *) &s, sizeof(s));
          cout << endl << "Add another y/n" << endl;
          cin >> ch;
        } outfile.close();
      }
      void disp() {
        ifstream infile;
        infile.open("STUDENT.DAT", ios::in | ios::binary);
        while (infile.read((char *) &s, sizeof(s))) {
          cout << endl << s.name << "\t" << s.clas << "\t" << s.
              city << "\t" << s.admno << endl;
        }
      }
    };
    
    int main()
    {
      data d;
      fstream outfile;
      outfile.open("STUDENT.DAT", ios::in | ios::out | ios::binary | ios::app);
     // getpass();
      system("CLS");
      int c;
      cout << "input c-";
      cin >> c;
      switch (c) {
      case 1:
        d.add();
        break;
      case 2:
        d.disp();
        break;
      default:
        ;
      }
      return 0;
    }
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
