<div>
<pre>The code is as follow:
#include <stdio.h>
void fn(int arr[])
{
for (int j = 0; j < 5; ++j)
printf("%d: %d\n", j, arr[j]);
}
int main()
{
fn((int[]) { 41, 42, 43, 44, 45 } );
return 0;
}
clang++ accepts it but g++ rejects it:
code5.cpp: In function 'int main()':
code5.cpp:11:13: error: taking address of temporary array
fn((int[]) { 41, 42, 43, 44, 45 } );
^~~~~~~~~~~~~~~~~~~~~~
Here is another code sample:
extern "C" int printf(const char*, ...);
int main() {
using A = int[1];
printf("%p\n", A{1} );
}
clang++ again accepts it, but g++ rejects it:
code6.cpp: In function 'int main()':
code6.cpp:4:17: error: taking address of temporary array
printf("%p\n", A{1} );
^~~~</pre>
