static_assert( 布尔常量表达式 , 不求值字符串 ) (1) static_assert( 布尔常量表达式 ) (2) (C++17 起) static_assert( 布尔常量表达式 , 常量表达式 ) (3) (C++26 起) 声明静态断言。如果断言失败,那么程序非良构,并且可能会生成诊断错误信息。
This convenience macro expands to the keyword_Static_assert. Example Run this code #include <assert.h>intmain(void){static_assert(2+2==4,"2+2 isn't 4");// well-formedstatic_assert(sizeof(int)<sizeof(char),// compile-time error"this program requires that int is less than char");...
static_assert(bind(monad(2))(monad)()==monad(2)()); (C++17 起) 额外要求 即使表达式E不会求值以上任何一项,但是如果求值它会导致运行时未定义行为,那么由实现定义E是否还是核心常量表达式。 即使表达式E不会求值以上任何一项,但是如果求值它会导致求值以下任何一项,那么未指定E是否还是核心常量表达式:...
