Hello,

I have to study  STL this semester. The below code is from my text book.

/* prog1.cpp, start here */

#include <vector.h>
#include <iostream.h>

void display(const vector<int> v);

void main()
{
   vector<int> vec1(3,11);
   vector<int> vec2;

   display(vec1);
   vec1.push_back(22);
   display(vec1);

   vec1.insert(vec1.begin(),33);
   display(vec1);

   vec1.erase(vec1.begin()+1,vec1.end()-1);
   display(vec1);

   vec1.pop_back();
   display(vec1);

   vec2=vec1;
   display(vec2);
}

void display(const vector<int> v)
{
   if(v.empty())
      cout << "Vector is empty\n";
   else
   {
      for(int i=0; i<=v.size()-1;i++)
         cout << v[i] << ' ';
      cout << endl;
   }
}

/* end here */

I compiled the above by typing:   gxx -s -o prog1.exe prog1.cpp
but DJGPP gave error messages as follow

e:/djgpp/lang/cxx/stl_vector.h:113: no type named `iterator_category' in
`int'
e:/djgpp/lang/cxx/stl_vector.h:113: no type named `value_type' in `int'

iterator_category<int>(const int &)':
e:/djgpp/lang/cxx/stl_iterator.h:126: confused by earlier errors,
bailing out

Could you guys tell me what I've been missing here ?

Thanx for your help
