Hi , I'm new to programming, I wanted to know if knowledge of C++ is enough to build a program that makes modifications in the system , like Tuneup Utilites program that repair registry errors, or check for hard disk failures , format it and check the mbr ...or it needs to know how the OS works and other stuffs!!
Second question is : using C++, is it easy to make your own scripting language like PHP !! is this correct ?
