C++11 allowed lambda functions to deduce the return type based on the type of the expression given to the return statement. The C++14 standard provides return type deduction in all functions, templates, and lambdas. C++14 allows return type deduction for functions that are not of the form return expressions. In this post, we explain the auto keyword, what is an auto type deduction, and how we…
The Lambda Expression construct is introduced in C++ 11 and further developed in the C++14, C++17, and C++20 standards. C++14 standard introduced thegeneralized lambda capture (init capture) that allows you to specify generalized captures, it allows to use move capture…
Lambda Expressions allow users to write an inline expression that can be used for short snippets of code in your C++ app which are not going to be reused and don’t require naming. The Lambda Expression construct is introduced in C++ 11 and further developed in the C++14…
What Does Deprecated Mean And How To Use Deprecated Attribute In C++?
September 15, 2023
C++ is very strong in every aspect of modern programming and evolves and refines itself even further with the release of each new C++ standard. While there are many new additions there are some features that are found not useful or dangerous in programming, thus the community offers its deprecation in the next standard and then it is generally removed in the following standard. C++14 came with a…
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…
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 examples,
How can I use use digit separators in modern C++?
In C++14, there is a new Digit Separators feature. The digit…
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…
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++ has an integer type std::sig_atomic_t that can be accessed as an atomic entity even in the presence of asynchronous…
