Suppose the following program is named x.cpp

#include <iostream>
#include <vector>

using namespace std;

template <class T>
class Vec : public vector<T>

        vector<T>::iterator begin()
        {
                cout << "non-const begin() is called" << endl;

        vector<T>::const_iterator begin() const

                cout << "const begin() is called" << endl;
                return vector<T>->begin();
        }
};

int main()
{
        return 0;
}

When I compile this program with g++ as
g++ -std=c++98 -pedantic -Wall -Wextra x.cpp

I am getting the following compilation errors:

x.cpp:10: error: expected `;' before "begin"
x.cpp:16: error: expected `;' before "vector"
x.cpp:16: error: expected `;' before "begin"
x.cpp:21: error: expected `;' before '}' token

Please help me fix the compilation errors.

#include <iostream>
#include <vector>

using namespace std;

template <class T>
class Vec : public vector<T>

class Vec // No need to inherit from vector

{
     public:
         typename vector<T>::iterator begin()
{
                 cout << "non-const begin() is called" << endl;
                 return vec.begin();
}

         typename vector<T>::const_iterator begin() const
{
                 cout << "const begin() is called" << endl;
                 return vec.begin();
}
     private:
         vector<T> vec;
};

int main()
{
         return 0;
}
