what is wrong here ?

#include <iostream>

using namespace std;

class myc
{
    int * arr;
  public:
        myc()
        {
            arr = new int[50];
        }

        int& operator[](int i)
        {
            return arr[i];
        }

        ~myc()
        {
            delete arr;
        }
};

class sup
{
    myc * arr;
  public:
        sup()
        {
            arr = new myc[50];
        }

        myc& operator[](int i)
        {
            return arr[i];
        }

        ~sup()
        {
            delete[] arr;
        }
};

int main()
{
    cout << "Hello world!" << endl;

    sup s;

    sup[0][0] = 72;

    cout<< sup[0][0]<<endl;

    return 0;
}

my above code is not compiling (as usual) , i am not understanding what exact error
the message at [][] operator is expected unqualified id before [ token ?
i use codeblocks with gcc compiler on windows

s[0][0] = 72;

thanks , but there is no space in between

    sup s;

    sup[0][0] = 72;

    cout<< sup[0][0]<<endl;

Your declaring 's' as an object of the sup class. Then instead of using the object of sup, you type sup[0][0] = 72 and use the class. Change that line to s[0][0] = 72 as guest said earlier.

sorry i didn't see it properly .
