Lab 00 - Hello World

---

Install Visual Studio Community 20xx on your computer.

Use the following steps in creating your lab:

1. Run Visual Studio Community and create an empty project.
2. Add the following C++ .cpp file (or write your own) to your project:

   #include <iostream>
   #include <fstream>
   #include <string>
   using namespace std;
   
   #ifdef _MSC_VER
   #define _CRTDBG_MAP_ALLOC  
   #include <crtdbg.h>
   #define VS_MEM_CHECK _CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF);
   #else
   #define VS_MEM_CHECK
   #endif
   
   /**	Write input file lines (as specified by argv[1])
   	to output file (as specified by argv[2]).
   */
   int main(int argc, char* argv[])
   {
      VS_MEM_CHECK                        // enable VS check for memory leaks
   
      if (argc < 3) return 3;
      ifstream in = ifstream(argv[1]);    // open argv[1] for input
      if (!in) return 1;
      ofstream out = ofstream(argv[2]);   // open argv[2] for output
      if (!out) return 2;
   
      // read input file lines and send to output file
      for (string line; getline(in, line);)
      {
         out << line << endl;
      }
   
      // **LEAK SOME MEMORY - REMOVE FOR FULL CREDIT**
      int* memory = new int(100);
   
      return 0;
   }

3. Set breakpoint on return statement to verify message.
4. Compile and execute.
5. Zip your hello.cpp file.
6. Submit the .zip folder and verify auto-grader results.

Instructions for submitting your lab:

• Zip all your lab source files (.cpp, .hpp, .h) into one folder. DO NOT INCLUDE YOUR WHOLE PROJECT!
• Submit your zipped lab source folder using the "Labs" tab on the class website.
• Your submitted lab source will be compiled and executed using a Linux g++ compiler.
• Both input and output files will be specified by command line arguments.
• An auto-grader will compare your output files with expected results and you will shortly receive a score.
• The auto-grade process may abort on the first error. If so, correct the error and try again.
• You may re-submit your zipped source as many times as you like.
• No score will be recorded for this lab nor is there a peer review!

Use the following test input and resulting output files in testing your Hello World lab.

The auto-grader will grade your lab as follows:

There is no peer review for this lab. However, if there were a peer review, the following rubric would be used:
