static_assert
在头文件<assert.h>中定义 |
|
|
---|---|---|
#define static_assert _Static_assert |
|
|
此便利宏扩展为关键字_Static_assert。
例
#include <assert.h>
int main(void)
{
static_assert(2 + 2 == 4, "2+2 isn't 4"); // well-formed
static_assert(sizeof(int) < sizeof(char),
"this program requires that int is less than char"); // compile-time error
}
