>Description:
Should a non-constant array be allowed in C/C++? I guess not. See the following code.
int main()
{
int c;
scanf("%d", &c);
int arr[c];
int p;
char arr2[c];
int another;
printf ("Terrible, diff=%d, diff=%d\n",
(char*)&c-(char*)&p, (char*)&p - (char*)&another);
return 0;
}
Seems that compiler treats it int arr[c] as int *arr. I don't think it should compile.
Thanks
