Assert And static_assert. The assert that we have seen so far is executed at run time. C++ supports yet another form of assert known as the static_assert and it performs compile-time assertion checking. It is present since C++11. A static_assert has the following general syntax. static_assert (bool_constexpr, message)

C++11 added another type of assert called static_assert. A static_assert is an assertion that is checked at compile-time rather than at runtime, with a failing static_assert causing a compile error. A static_assert takes the following form:

static_assert (bool_constexpr, message) static_assert. A static_assert is a statement in C++ which tests for a condition like constant expression at the compile time of the program. If the condition results as 1 or true, the static_assert declaration has no effect. _Static_assert(FOO_VERSION >= 2, "foo version 2+ required"); Static assertions can also be used in combination with the new _Alignof operator and generic selection mechanism to enforce alignment and type constraints at compile-time: A static_assert() has a mandatory first parameter, the condition, that is a bool constexpr. It might have a second parameter, the message, that is a string literal. From C++17, the second parameter is optional; before that, it's mandatory.

In C++11 a compile-time assert mechanism was added: static_assert. static_assert acts like run-time assert except that the checked-condition must be a constant-expression (that is, an expression that can be evaluated at compile-time); the checked-condition must be a boolean expression, or an expression that can be converted to a boolean.
