The formatting function has been combined with output in C++23, which provides [16] the std::print command as a replacement for printf(). As the format specification has become a part of the language syntax, C++ compiler is able to prevent invalid combinations of types and format specifiers in many cases.
The term magic number or magic constant refers to the anti-pattern of using numbers directly in source code. This has been referred to as breaking one of the oldest rules of programming, dating back to the COBOL , FORTRAN and PL/1 manuals of the 1960s. [ 1 ]

[13]: 651–652 [1]: 182–184 User code can define custom types that async methods can return through custom async method builders but this is an advanced and rare scenario. [17] Async methods that return void are intended for event handlers ; in most cases where a synchronous method would return void , returning Task instead is recommended ...
The increment operator increases, and the decrement operator decreases, the value of its operand by 1. The operand must have an arithmetic or pointer data type, and must refer to a modifiable data object. Pointers values are increased (or decreased) by an amount that makes them point to the next (or previous) element adjacent in memory.
