Modern C++ has a lot of useful functions coming from C. One of them was the gets() function that we use to get string inputs and that we were able to use in C++11 or earlier. In C++14, the gets function was removed, while fgets or other input functions remain there. If you have older C++ code that uses the gets() functions your C++14 version compiler will not compile it. Why was the gets function…
A programming language consists of a lot of expressions in our source code. One of elements of expressions in C++ are literals. A more specific type of literal is Integer Literals. Integer literals are primary expressions that allow values of integer types (i.e., decimal…
In the history of modern C++, the C++14 standard brings us some very useful features. C++14 comes with the digit seperators feature. In C++14 and above, we can use the digit separator to separate integer numbers. In this post, we explain, how to use digit separators in…
C++14 brings us fewer but useful features to modern C++ than the standards preceding it. The creator of C++, Bjarne Stroustrup says that improvements in C++14 were deliberately lower in quantity compared to C++11. One of the small but useful features is the introduction of “Binary Literals”. C++14 comes with the Binary Literals feature, and in this post, we explain how we can use…
C++11 allows the use of atomics in signal handlers, and with the advent of C++ 17 the signal handler feature was again improved. Thestd::atomic_flagis an atomic boolean type that is guaranteed to be lock-free and can be used in signal handlers. Moreover,the…
C++11 allows the use of atomics in signal handlers. In C++17 the signal handler feature is further improved. The std::atomic_flag is an atomic boolean type that is guaranteed to be lock-free and can be used in signal handlers. Moreover, the <csignal> header in C++…
Modern C++ has many features to aid multi-thread programming that allow applications to be faster and more responsive. The C++11 standard offers the possibility of moving an exception from one thread to another. This type of movement is called propagating exceptions, exception propagation; also known as rethrow exception in multi-threading. To do that, some modifications have been made to the…
C++ is very strong in every aspect of modern programming. Volatile types are used with the volatile keyword. It is a lesser known type qualifier that is important to read types or objects whose value can be modified at any time. The volatile keyword is useful in…
Since the C++11 standard, the Concurrency Support Library includes built-in support for threads (std::thread) with atomic operations (std::atomic). C++11 provides both weak and strong compare-and-exchange operations in multi-threading applications. Since C++11, weak compare…
Since the C++11 standard, the Concurrency Support Library includes built-in support for threads (std::thread) with atomic operations (std::atomic). C++11 provides both weak and strong compare-and-exchange operations in multi-threading applications. Since C++11, strong compare and exchange are used in modern C++ standards such as C++14, C++17, C++20, and in other new standards. In this post, we…
