firstly include the code in code tags to improve readability and secondly the
void main must be changed to int main and include an return 0 at the end of the main
|
|
Use code tags, its easier to read.
Secondly, main() should ALWAYS return an int. Anyone who says otherwise should be slapped across the face (along with virus writers :D).
EDIT:
struct tm *Sys_T = nullptr; use nullptr instead of NULL when working with pointers.

Actually, that isn't required anymore for the
int main() (it is called for you, but only for the main function--below is perfectly legal C++ code now): |
