Spring 2020 Project 00 - Lab Week One

Steps to complete this in lab assignment:

The goal is to take you through the entire lifecycle of a project.

  1. Accept the Github Classroom Assignment Link. (Since you're reading this, you've likely already done this.)
  2. Clone the repo to your local machine.
  3. Open the project in CLion (File -> Open -> Navigate to the folder containing the cloned repo files) or IDE/editor of your choosing.
  4. The "scenario" for this assignment is to open a file that contains integers and print the integers to the terminal and to a separate file AND include the average of the numbers at the end. Currently, the code in main.cpp prints to the screen and to a separate file. You need to:
    • add code to main.cpp to calculate the average of the numbers read in.
    • print the average to both the terminal and the output file.
  5. After you save main.cpp, build the project. In CLion, click the Hammer in the upper right corner of the window. If there are any compile errors, they'll show up now. Fix them and rebuild.
  6. Commit your changes to github.
  7. Eli, pick up here with modifying the CMakeLists.txt file and adding command line args in CLion. then run. if all good, update build.yaml. commit again. push to github. check actions output in GH. etc.

Input and Output Files

As you begin using input files and output files with this project, you'll need to modify the CMakeLists.txt file and the .github/workflows/build.yaml files.

Place any input files in the folder that contains your source code. When your project is built, it will be copied into the build directory by CMake.

  • CMakeLists.txt

    • Open it and look for the commented section (with # signs). Edit the set(input01 "") etc. based upon how many files you need.
    • there should be one set(...) statement per input file
    • you DO NOT need to list output files in CmakeLists.txt.

  • .github/workflows/build.yaml

    • Open this file and look for the INPUT_FILES: command near the top.
    • List the input file names in the order they should be sent to argv of main.
    • OUTPUT file need to be listed here as well in the OUTPUT_FILES: section.
    • For example: 
      INPUT_FILES: input01.txt
OUTPUT_FILES: output01.txt
      would be equivalent to the following execution command: 
      ./executableName input01.txt output01.txt
