Lambda Expressions allow users to write an inline expression that can be used for short snippets of code which are not going to be reused and don’t require naming in your C++ app. The Lambda Expression construct is introduced in C++ 11 and further developed in the C++17 and C++20 standards. Because of its syntax and definition with [ ] and ( ) and { }, sometimes it is hard to understand or…

The Printf function is one of the oldest and most powerful functions that we use to print out strings or that we use to print out to a stream or to another string. Do you want to learn the basics of printf() function? Who says you can’t use printf() in Modern C++? Who says printf() is oldish ? 🙂Before we used cout cin in C++ (actually I don’t use them in my Modern Apps), we were…

Mobile android applications developed in C++ Builder requires permissions to use some part of mobile devices (sensors, camera etc..). These should be allowed by the user. an these permissions can be checked over the project options from Project > Options > Application > Uses Permissions section. Some of these permissions were listed in this document…
There are a lot ways to operate on files in C and C++. In C programming is enough to use FILE, fopen(), fclose() operations. In C++ FileOpen().was enough to operate before. In Modern C++ because of multiplatform operating systems, global languages and for the other benefits…
Unicode standard for UnicodeString provides a unique number for every character (8, 16 or 32 bits) more than ASCII (8 bits) characters. UnicodeStrings are being used widely because of support to languages world wide and emojis. In modern C++ nowadays there are two types…
There are two kinds of if statements in modern C++: runtime if and compile-time if constexpr.
Runtime if looks like:
if (condition) statement-true
if (condition) statement-true else statement-false
In both forms of above if the result of condition yields to true, then statement-true is executed. Otherwise (in the second form of above) the statement-false is…
