Test objectivesTesting is the process of examining software in order to identify errors. However, tests can be used for other purposes as well: as documentation. The tests reflect the expected response of the system to any stimulus. Information recorded in the form of tests can be useful when familiarizing yourself …
Predictably, question 6 fails the most – the answer is different for C ++ 11 and C ++ 98. Moreover, in the new standard, the function began to work worse. In the test, you were asked to evaluate the correctness and computational complexity of 6 different solutions to the same …
Recently, posts rarely appear here, since we are trying to translate quantity into quality. In particular: from scattered materials on C ++ we collect something like a textbook for beginners (now only the first 4 lessons are ready);the continuing education textbook should contain the most up-to-date information, but this information …
Ask an abstract C ++ programmer what are the most common mistakes and are most likely to hear: null pointers, division by zero, undefined behavior, array out of bounds, uninitialized variables. But this has little to do with reality. Rather, it is a set of mistakes that we have all …
The virtual machines of Java, Python, and other interpreted languages perform garbage collection, profiling, and optimizing code themselves, including compiling individual chunks. However, sometimes they don’t work fast enough, but what can you do about it? – It turns out that virtual machines have settings that allow you to select …
If you have been programming for a long time, you probably were engaged in disassembling the code and asked the question “Why did the compiler optimize the code in one case, but not in the other?” Usually, to answer a question, you need to do a little research with small …
