C + + Basics

C + + is an intermediate language that was designed and developed by Bjarne Stroustrup in Bell Labs in 1979. C + + has further expanded and perfected the language, and is an object-oriented programming language. C + + can run on a variety of platforms, such as Windows, MAC operating systems, and various versions of UNIX.

#include <iostream>  // standard input/output stream usingnamespace// namespace, Reference C + + standard library space. Do not add this sentence below cout and Endl will write this std::cout,std::endl; int Main () {    "Hello, world!  "<<//can use" \ n "instead of Endl. "\ n" indicates a string with the content as a carriage return character. Std::endl is a stream operator, outputs a newline character, and immediately flushes the buffer. return 0;}
