Before learning C++ detail, I would like to give you a whole abstraction at first. For learning syntax, you would know, actually, it is like a "spell" in Harry Potter. You need to combine several correct words to instruct your computer how to achieve what you want in that program. ex. #include<iostream> using namespace std; int main(){ cout<<"Hello World"; } cout<<"Hello World"; →it is an instruction to print out "Hello World" on command line, and this cout is stored in a namespace std to let you use, but also included in a library <iostream> .
