Compiling, Linking and Libraries1.Вопрос 1 GCC stands for: 1 / 1 балл  GNU Compiler Collection  Geneva Computation Corporation Great Computer Compiler GNU Compiler for C Правильно This is the correct answer 2.Вопрос 2 A good choice of compiler options for day-to-day use would be: 1 / 1 балл gcc -M -H -O3 -E program.c gcc -Wall -I /tmp/include -L /tmp/lib program.c gcc -O2 -Wall -pedantic program.c gcc -O0 -Wall -ansi program.c Правильно This is a standard bit of advice 3.Вопрос 3 Why might you choose to link your program statically, rather than use a shared library version? 1 / 1 балл The static program will use less memory The static program need not have an open source license, while the shared library version cannot be closed source The static program will not use new versions of shared libraries as they become available, and thus may avoid breakage and bugs The static program will load and execute more quickly Правильно Yes, some bugs can be avoided 4.Вопрос 4 To find the shared libraries used by /usr/bin/cp you can do (Select all answers that apply): 1 / 1 балл  ldd /usr/bin/cp Правильно You can run ldd directly on the executable ldd $(which cp) Правильно You can run ldd indirectly on the executable using which  gcc -ldd /usr/bin/cp find -libso /usr/bin/cp 5.Вопрос 5 Which statements are true (Select all answers that apply): 1 / 1 балл Use of shared libraries can cause bugs because the application may conflict with the new library version Правильно Unfortunately, there may be unforeseen problems and inadequate testing Use of shared libraries saves memory Правильно Only one copy of the library needs to be kept in memory if more than one application is using its contents Applications can load faster when using shared libraries Правильно If the relevant data is already in memory it need not be loaded again Use of shared libraries enables applications to stay up to date with new library features without being recompiled Правильно The application will automatically use the new features Test 7 |
