hi

i almost have this code complete but i am getting 2 errors.
I am supposed to use function declared inside/outsie class

#include<iostream>
using namespace std;
#include<conio.h>


    class person
         {
         char name[30];
         int age;
         public:
                 void getdata(void); //inside declaration
                 void display(void);
           };
        
          main()
           {
            person p; //object of type person
            p.getdata();
            p.display();
            getche();
              }
        
          void person::getdata(void)  //outside declaration
              {
               cout << "Enter name: ";
               cin >> name;
               cout << "Enter age: ";
               cin >> age;
                 }
          
          void person::display(void)
               {
                cout << "\nName: " << name;
                cout << "\nAge: " << age;
                }

You cannot write a function inside another function.

There are functions inside main(). Move those outside of main().

Your program is mostly correct. The error is in header file. Write the header file iostream like this. #include <iostream.h> and remove the using namespace std. Insha Allah your program will execute with out any error.

iostream.h is a pre-ANSI C++ header from 1998. It is obsolete.

The program is correctly includung iostream.

Also. the std namespace is vital to avoid name clashes between your code and the library. iostream.h did not support namespaces beacuse it is too old.

Please do not use this old header. Remember, C++ header files do not have extensions. Headers wth .h extensions are for C and not C++.
