Try this:

syntax:

type class-name::operator[](int index)
{
//operations
}

e.g.:

const int SIZE=5;
class arraytype{
int a[SIZE];
public:
arraytype(){
int i;
for(i=0;i<SIZE;i++) a[i]=i;
}
int operator[ ](int i){return a[i]; }
};
int main( )
{
arraytype ob;
int i;
for(i=0;i<SIZE;i++)
     cout<<ob[i]<<" ";
return 0;
  }
