Good point. :laugh:

According to MSDN[^], "The main difference between printf_s and printf is that printf_s checks the format string for valid formatting characters, whereas printf only checks if the format string is a null pointer." So, basically, if I understand correctly, it's not really a security feature as its name implies, it's a debug feature. The whole "uncontrolled format string" problem it's supposed to solve could be avoided by basic knowledge of what printf actually does. EDIT: I don't even know why I'm not just using cout
