which of the following is a valid member function that is guaranteed to run last for an object of class type Student?

  1. which of the following is a correct way to declare a member function of a class so that it will be guar- enteed to not change the member data of the calling object? int Compute(int &x) const;
  2. T/F: if a binary operator is overloaded and written as a true stand-alone function, the function takes two parame- ters
  3. T/F: if an array of Fraction objects is declared to be size 10, but is only storing 7 Fractions, this should be denoted by putting a null character '/0' at the end false
  4. T/F: the command "g++ - c circle.cpp" invokes the com- true pile stage but not the linking stage of the compilation process
  5. T/F: an l-value is an expression that represents a mod- true ifiable and non-temporary storage location
  6. T/F: if a member data variable of a class is declared to be static, its value can differ for separate objects of that class type
  7. T/F: a friend of a class has access only to the public section of that class false false
  8. T/F: function calls are checked against their prototypes false for correctness during the linking stage of a program build
