Divide/Split Code to Multiple (source/header/class) files in c++ and c# on Visual Studio 2017 11
Learn how to add #multiple #files to a single file #program and #divide/#split #code into multiple files. How to #compile and #run a #project with multiple #source,#class and #header files in c plus plus and c sharp projects.
c++ code:
//Source.cpp is a source file
#include ＜iostream＞ //for cout
#include ＜fstream ＞ // for ofstream/ifstream
#include ＜string ＞ //for ＜＜ and getline
#include ＜vector ＞ //for vectors
#include＜list ＞ //for lists
#include "Header.h"
//class file_element
//{
//public:
// std::string line;
