Building status (live master brach), check logs for clang static analyzer & valgrind memcheck output.

Development status:

DONE

• command line arguments with exit code:
  • 1 ← arguments number is less than 3;
  • 2 ← the second argument isn't an action;
  • 3 ← input file isn't accessible;
• compressing
  • the first input file pass;
  • chars occurrence statistic;
  • the second input file pass;
  • output file writing, header:
    • numbers bits count;
    • symbols count;
    • symbols occurrence statistic;
    • end of statistic mark;
  • output file writing: content;
• Huffman coding
  • Huffman tree raising;
  • encoding;
• extracting
  • input file reading, header:
    • numbers bits count;
    • symbols count;
    • symbols occurrence statistic;
    • end of statistic mark;
  • input file reading: content;
  • output file writing;
• Makefile (design assignment requirement, cmake is default)
  • 'all' target
  • 'clean' target

TUNEDUP

• compressing
  • predefined symbols list;
• extracting
  • bytes cache;
  • bitwise operations speed-up;
• I/O speed-up
  • unlocked std I/O;
  • fgetc → fread (~ kByte);
• architecture-bit numbers.

NEEDOPTIMIZATION

• I/O
  • fputc → fwrite;
