Weakly Typed Languages

• EQUIVALENCE statement between variables of different types
• Type checking for parameters not done

• Variant Records: Tag can be ommitted

• Variant Records: Tag can be ommitted
• WORD type used for pointers

• UNCHECKED-CONVERSION library function to manipulate addresses as integers

• void pointer:

  int main()
  {
    void * voidPtr;
  
    // Assign to point to double
    voidPtr = new double(5.345);
    // Read double back
    cout << * ((double *)  voidPtr) << endl;
    // Read double as int
    cout << * ((int *)  voidPtr) << endl;
                                                                                  
    // Delete pointer
    delete (int *) voidPtr;
                                                                                  
    return 0;
