Tasks

Complete the task of the chosen difficulty level for your variant number.

For this introductory topic, the data is set in the code. The difficulty grows through the presentation of the output, checking the calculations, reproducible builds, and the Git history. You don’t need to introduce classes or parse command-line arguments unless the task requires it.

Procedure

1. Study the theory, check that the C++ components are installed, and create a separate console project for the chosen task.
2. Write down the task, the input data, and the expected result. For a numeric problem, calculate a check result by hand before running the program.
3. Implement the program with a single main, and set the options for the standard, warnings, and encoding. Fix build errors and check the warnings; run the current build.
4. Check the units of measurement, the precision of numbers, Ukrainian characters, borders, and alignment. Change one input value, predict the new result, and compare it with the actual one.
5. Perform the Git actions or build comparisons required by the task. Before committing, review the changes and exclude service files; don’t pass off fictional sample data as real personal information.
6. Prepare a report: the task, the code, the build options and command, the actual output, the check calculations, and, if needed, the commit history. Hand in the source files in the way agreed with the instructor.
7. At the defense, explain every line of the program, the build stages, and the contents of the commits; make a small change and rebuild the project.
