Question

1. Every C++ program must have:

    A. a cout statement    B. function main             

  C. a #include          D. All of the above

          

     2. main() is a method that is part of the ‘Standard Library’.

         T__   F__   

     3. Inside a ‘Console Application’, a ‘Project’ may implement multiple

         ‘Solutions’.

                       

         T__   F__   

     4. The C++ source-code files are listed with the extension .sln.

    T__   F__    

      5. It is recommended to start the name of an identifier with a digit.

        T__   F__    

      

      6. The following declaration is legal in C++:

             int sample{23.5};  

                                   

         T__   F__

      7. The following functional-declaration-style is no longer legal in C++:

            int sample(23.5);  

                                 

         T__   F__

      8. The following statement is not accepted by the compiler:

         char c{500};       

                          

     T__   F__            

                      

9. But the following statement is accepted by the compiler:

          char c(500);       

T__   F__

     10. The following code-segment of ‘main()’ is syntactically correct:

  

             const int x;         

             x{5};

        

         T__   F__

    11. The following line of code is legal in C++:

             const int x = 65,535;      

         T__   F__         

12. The following declaration is accepted by the compiler:

        int return;        

    T__   F__

     13. /n is a new-line symbol.

         T__   F__  

14. int x;

    int y;          

    const int z{};  

    Which statement will cause a compile error?

                                                      

    A. x = y = z;   B. x = z = y;   C. x = y = 'A';   D. x = y = 10000;      

                   

15. int x{4};

    int y;

    y = x++ + 1;

    What is the value of variable y after the above statements execute?  

                                                 

    A. 4      B. 5     C. 6     D. 7     E. None of the above

16. int x{4};

    int y;

    y = --x + 1;

    What is the value of variable y after the above statements execute?

                                                   

    A. 4      B. 5     C. 6     D. 7     E. None of the above

17. int x{11};

    int y;

    y = x % 3;

    What is the value of variable y after the above statements execute?

                                            

    A. 3     B.2.2   C. 2    D. 3.33   E. None of the above

18. x != y is not the same as (x>y || x<y)  

    T__   F__

19. It is correct to write x%y if either x or y is float.

    T__   F__     

     20. The following code-segment of ‘main()’ is flagged with an error:

             int x{11};

             double y = (double)x / 2;           

         T__   F__
