<cassert>

Includes the C Standard library header <assert.h> and adds the associated names to the std namespace. Including this header ensures that the names declared using external linkage in the C Standard library header are declared in the std namespace.

Note

<assert.h> doesn't define the static_assert macro.

Syntax

#include <cassert>

Macros

#define assert(E)

Remarks

assert(E) is only constant, if NDEBUG is defined where assert is last defined or redefined, or E converted to bool evaluates to true.
