static_assert

Defined in header <assert.h>
#define static_assert _Static_assert
+
(since C11)
(removed in C23)

This convenience macro expands to the keyword _Static_assert.

+

Example

#include <assert.h>
+ 
+int main(void)
+{
+    static_assert(2 + 2 == 4, "2+2 isn't 4");   // well-formed
+ 
+    static_assert(sizeof(int) < sizeof(char),   // compile-time error
+                  "this program requires that int is less than char");
+}

Notes

Since C23, static_assert is itself a keyword, which may also be a predefined macro, so <assert.h> no longer provides it.
