The questions are from 5 to 8:

---------------------------------------------------------------------------

5. Given the declaration

Contact new_contact;

which of the following instructions will execute without error? On the answersheet for question 5, put the letters of the ones that execute without error on the answersheet for this question.

(a) new_contact.set("Xavier,Francis,8009367777,fx32@abc.cuny.65");

(b) new_contact.set("donald,duck,7771234567,dduckatdisney");

(c) new_contact.set("Dr.,Strangelove,2223331888,drstrangelove@hollywoodandvine");

(d) new_contact.set("root,user,1111111111,root@192.168.1.0");

(e) new_contact.set("Willy-Nelson,O'Flanagan,6461118888,willi@theHem@music.org");

(f) new_contact.set("Willy-Nilly,O'Keefe,6461118000,willinilli2@music.org");

6. The contact.cpp _le has the following include directives:

(a) #include

(b) #include

(c) #include

(d) #include "contact.h"

(e) #include "name.h"

Are each of these directives necessary for this file to be compiled without error? On the answersheet,

for question 6, write the letters of the include directives above that cannot be removed without introducing a compiler-error .

Answer questions 7 and 8 based on the following declarations

Name security_guard("Jane");

Name office_person("Joe");

Name strange_person("Jane", "Doe");

Name unknown;

7. Which of the following are error-free? List the letters of the ones that are error-free on the

answersheet for question 7.

(a) Contact c1( unknown);

(b) Contact c2( security_guard );

(c) Contact c3( strange_person, "8886661234");

(d) Contact c4( "Jane", "Doe", "", "");

8. What is output by the code below? Enter a 0 or a 1 for question 8.

Contact c5("Jane", "", ""), c6(security_guard, "", "");

if ( c5 == c6 ) cout << 0 ; else cout << 1 ;
