Hmmmmm what language do you speak?
Just so you know programming is not something you learn overnight, it takes atleast a year to get a good understanding of C++. I however took classes in Java, I know some about C++, but only because C++ and Java are similar languages. I could help you learn Java but I reccommend you find someone who knows a lot about C++, because I won't be able to help you until Ive had a little more experience in it.
BTW: "Hello World" is just a program beginners write that prints out "Hello World" in a console. Its very beginner level stuff, just gets you an feel of what coding is like.
You can probably start to teach yourself, but u need to find a C++ compiler and some tutorial or guides.... Ummmm I dont want to suggest any because Im not experienced in C++, but ask around in the C++ section. Ask for a Compiler thats easy for beginners to use and some good tutorials.
