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…
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…
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 <csignal>header in C++ has an integer typestd::sig_atomic_tthat can be accessed as an atomic entity…

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…
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 memory-mapped applications, generally these are from a hardware device, from a sensor, from an input device, or data from on an IoT. For…
