The utility file provides various utilities: class template std::pair (two-member tuples), compile-time integer sequences, helpers in constructing vocabulary types, functions such as std::move and std::forward, and many more. The namespace std::rel_ops for automatically generating comparison operators is deprecated in C++20 in favor of new ...
In the C++ Standard Library, several algorithms use unqualified calls to swap from within the std namespace. As a result, the generic std::swap function is used if nothing else is found, but if these algorithms are used with a third-party class, Foo, found in another namespace that also contains swap(Foo&, Foo&), that overload of swap will be used.
For example, the entire C++ Standard Library is defined within namespace std, but before standardization many components were originally in the global namespace. A programmer can insert the using directive to bypass namespace resolution requirements and obtain backwards compatibility with older code that expects all identifiers to be in the ...
The C standard library, sometimes referred to as libc, [1] is the standard library for the C programming language, as specified in the ISO C standard. [2] Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it. [3]

The Summary. U.S. life expectancy jumped to 78.4 years last year, the highest it has been since 2019, before the pandemic. A decline in Covid deaths was a primary factor in the upward trend.
[citation needed] Some aspects of the returned object are implementation-defined, such as std::type_info::name(), and cannot be relied on across compilers to be consistent. Objects of class std::bad_typeid are thrown when the expression for typeid is the result of applying the unary * operator on a null pointer. Whether an exception is thrown ...
