You'll need to make tasks, code of every task must be uploaded to separate branch in private repository in github (preferred)
or any other, submit avery task as merge request/pull request. Don't use external libraries (if something else not specified).
Build system - cmake.

Git with UI: SourceTree (Windows), Sublime Merge (Linux)


Task 1:
Write a console application that accepts 2 strings as an input from user (text for anagram and text with filtering symbols).
If text with filtering symbols is empty, than ignored symbols are digits and non alphabetic symbols.

Tasks for C course.
Common requirements:
- don't use external libraries (if something else not specified)
- build system make/cmake (must be in every task)
- compilation with options '-O0 -g3 -Wall -Wextra -Wpedantic -std=c11'
- error handling
- all task must be checked with valgrind for memory leaks: 'valgrind --leak-check=full --show-leak-kinds=all --track-origins=yes --verbose /path/to/your/executable' (or with log file: 'valgrind --leak-check=full --show-leak-kinds=all --track-origins=yes --verbose --log-file=valgrind-out.txt /path/to/your/executable')
