const gives an error ...

[SH4D3H]

I started C++ again after some time, and Im no pro or anything, but i dont know what im doing wrong here br]const int SIZE = 100;

My compiler stops and gives an error the should be on this line.
Whats wrong with it?

I made a simple program to do inventory thats where the line is from. Though it gives more errors than only the const
Here's the complete code (and yes i shud use files to save to )

#include <iostream>
#include <cctype>
#include <cstring>
#include <cstdlib>
using namespace std;

const int SIZE = 100;

struct inv_type {
   char item[40];
   double cost;
   double retail;
   int on_hand;
   int lead_time;
}    invtry[SIZE];

void enter(), init_list(), display();
void update(), intput(int i);
int menu();

int main(int argc, char *argv[])
{
   char choice;
   
   init_list();
   
   for(;;) {
       choice = menu();
       switch(choice) {
        case 'e': enter();
         break;
        case 'd': display();
         break;
        case 'u': update();
         break;
        case 'q': return 0;
       }
   }
}

void init_list()
{
   int t;
   
   for(t=0; t<SIZE; t++) *invtry[t].item = '\0';
}

int menu()
{
   char ch;
   
   cout << '\n';
   do {
       cout << "(E)nter\n";
       cout << "[img]http://xtcomputing.com/xtboard/beer.gif[/img]isplay\n";
       cout << "(U)pdate\n";
       cout << "(Q)uit\n\n";
       cout << "Choose one : ";
       cin >> ch;
   } while(!strchr("eduq", tolower(ch)));
   return tolower(ch);
}

void enter()
{
   int i;
   
   for(i=1; i<SIZE; i++)
       if(!*invtry[i].item) break;
       
   if(i==SIZE) {
   cout << "List full.\n";
   return;
   }
   
   input(i);
}

void input(int i)
{
   char str[80];
   
   cout << "Item: ";
   cin >> invtry[i].item;
   
   cout << "Cost: ";
   cin >> invtry[i].cost;
   
   cout << "Retail price: ";
   cin >> invtry[i].retail;
   
   cout << "On hand: ";
   cin >> invtry[i].on_hand;
   
   cout << "Lead time to resupply (in days): ";
   cin >> invtry[i].lead_time;
}

void update()
{
   int i;
   char name[80];
   
   cout << "Enter item: ";
   cin >> name;
   
   for(i=0; i<SIZE; i++)
       if(!strcmp(name, invtry[i].item)) break;
       
   if(i==SIZE) {
   cout << "Item not found.\n";
   return;
   }
   
   cout << "Enter new information.\n";
   input(i);
}

void display()
{
   int t;
   
   for(t=0; t<SIZE; t++) {
       if(*invtry[t].item) {
          cout << invtry[t].item << '\n';
          cout << "Cost: $" << invtry[t].cost;
          cout << "\nRetail: $";
          cout << invtry[t].retail << '\n';
          cout << "On hand: " << invtry[t].on_hand;
          cout << "\nResupply time: ";
          cout << invtry[t].lead_time << " days\n\n";
       }
   }
}
