Welcome to this project.

Here are some small programs using C/C++, and they are very useful.（Most of them are very simple, even small programs!）

So what's in this project?

Let me take an example for you.

One day, Xiao Min came to a certain company. The company has a new product that needs to be sold (printed into posters). Now there are A Printing Factory and B Printing Factory. A's fee standard is: 0.2 yuan for each poster, plus 500 yuan for copyright. B's fee standard is: 0.4 yuan for each poster, no copyright fee, please use C/C++ to do it. A program to print 3000 copies of how many yuan!

Let's analyze it.First, set the company want to print x copies. So we know: A need : x multiply 0.2+500 yuan, B need : 0.4 multiply x yuan. Now we can write：

  int x;
  cout<<"Please input the number of printed documents.：";
  cin >> x;
  cout << "A printing factory will receive" << 0.2 * x + 500 << "yuan！" << endl;
  cout << "B printing factory will receive" << 0.4 * x << "yuan！" << endl;  

Complete code:

  #include <iostream>
  #include <ostream>
  
  using namespace std;
  int main() {
  int x;
  cout<<"Please input the number of printed documents.：";
  cin >> x;
  cout << "A printing factory will receive" << 0.2 * x + 500 << "yuan！" << endl;
  cout << "B printing factory will receive" << 0.4 * x << "yuan！" << endl;  
  return 0;
}

This project is handed over to A&B and you can find him in the branch.

So what environment do you use to do it?

Yo, is a good question, let me tell you:

• system:Windows Version 10 1909 (Enterprise）
• CPU：Intel(R)Core(TM) i5-5200U @ 2.20GHz
• editor: Dev-C++ 5.11
• translater:TDM-GCC 4.9.2 64-bit Release

You can download translater&editor in the branch Dev-Cpp.
