6. Given a member function mf of class C and the declaration Cc1i, which is the proper function call? a. c::mf(c1) b. Cmf(c) c. mf(cl) d. clmf() 7. Having individual source files that can be compiled to object files which can then be linked into an executable a. improves the organization of large applications b. minimizes the time necessary to rebuild an application's executable c. allows code to be easily reused in several applications d. all of the above 8. The include guard at the top of an . h file a. provides the name of the file to the compiler b. is only necessary if the file is included by the corresponding .cpp file c. is only necessary if there are overloaded functions headers present in the file d. prevents the . h file from being copied into the source more than once 9. After modifying the contents of a h file a. all the source files of the entire application must be recompiled b. those source files that include the . h file must be recompiled c. only the corresponding .cpp file must be recompiled d. no recompilation is necessary, only linking need be performed e. none of the above
