C++ no match for 'operator []'

I wrote a little students management program using structs, and when I try to compile it, an error appears:

Code:
luke@luke-desktop:~/Desktop/ProgII$ g++ recStudents.cc
recStudents.cc: In function ‘void add(TList&, Tstudent)':
recStudents.cc:114: error: no match for ‘operator[]' in  ‘Slist[(Slist->TList::number ++)]'

Here follows the code (I cut some irrilevant parts):

Code:
#include <iostream>
#include <iomanip>

using namespace std;

struct Tstudent
{
   char surname[50];
   char name[30];
   int age;
   float average;
};

struct TList
{
   Tstudent list[100];
   int number;
};

int menu();

void add(TList &, Tstudent s);

...

int main()
{
   ...

   Tstudent student;

   TList Slist;

   Slist.number = 0;

   cout << "\nSTUDENTS MANAGEMENT SYSTEM";

   do
   {
      choice = menu();

      switch (choose)
      {
        case 0: cout << "\nProgram terminated.\n";

                    break;

         case 1: add (Slist, student);

                     break;
      ...
...
}

...

void add (TList &Slist, Tstudent s)
{
   bool stud = true;

   char answ;

   if ( Slist.number < 100 )
   {
      while ( stud )
      {
         cout << "\n-New student-\n\nSurname: ";
         cin >> s.surname;

         cout << "\nName: ";
         cin >> s.name;

         cout << "\nAge: ";
         cin >> s.age;

         cout << "\nAverage: ";
         cin >> s.average;

         cout << "\nSave [y/n] ? ";
         cin >> answ;

         if (answ == ' ' || answ == 'y')
         {
            Slist[Slist.number++] = s;  // here's the problem

            cout << "\nStudent added.\n";

            stud = false;
         }

         else cout << "\nStudent not added.\n";
      }
   }

   else cout << "\nCan't add new students: the list is full.\n";
}

...

How can I solve this?
