};
When IsClassT<int>::Yes is evaluated, 0 cannot be converted to int int::* because int is not a class, so it can't have a member pointer. If SFINAE didn't exist, then you would get a compiler error, something like '0 cannot be converted to member pointer for non-class type in...

Should I use char** argv or char* argv[]?
...It will behave as a pointer, because as explained earlier an array will be converted to a pointer when its value is read. But it should not be confused with pointers.

char c[10];
char **c = &c; // does not work.
typedef char array[10];
array *pc = &...
