Parses str interpreting its content as an integral number of the specified base, which is returned as an int value. If idx is not a null pointer, the function also sets the value of idx to the position of the first character in str after the number.

Specifically, std::rotate swaps the elements in the range [first,last) in such a way that the elements in [first,middle) are placed after the elements in [middle,last) while the orders of the elements in both ranges are preserved. 2) Same as (1), but executed according to policy. This overload does not participate in overload resolution unless.Header Files. The C++ standard specifies the entire set of header files that must be available to all hosted implementations. Actually, the word "files" is a misnomer, since the contents of the headers don't necessarily have to be in any kind of external file.

The C++ language, for example, includes the functionality of the C standard library in the namespace std (e.g., std::printf, std::atoi, std::feof), in header files with similar names to the C ones (cstdio, cmath, cstdlib, etc.).
