Every test was successfully run multiple times (race conditions making outputs unpredictable should be avoided). Note that both sut.c and sut.h have been modified, and that the header file queue.h has been added in order to provide support for queues. You will find below instructions to run the five tests provided as support material.

For tests 1 to 4 you may compile and run the tests as follows:

gcc test{i}.c sut.c -pthread
./a.out

Note that {i} should be replaced by the index of the test.

For this test you will need to manually set the value C_EXECS_COUNT defined in sut.h to 2 in order to create two C-Exec threads. You can then proceed to compile and run the test file as with previous tests:

gcc test5.c sut.c -pthread
./a.out
