Executor

Sat, 11 Feb 2023 00:00:00 +0000

Executor is a concurrent programming project. It is a program that executes tasks, monitors their latest outputs (during execution) and terminates them if desired.

The handling of processes has been synchronized in such a way that the Executor immediately informs about task completion and continuously cleans up finished processes or threads it creates. All of this is done without using busy waiting, ensuring CPU resources are not wasted.

A detailed task description (in Polish, though) can be found at the GitHub link below.

Sparse Multivariate Polynomials

Mon, 21 Jun 2021 00:00:00 +0000

This is a comprehensive project written in C, aimed at implementing fundamental operations on sparse multivariate polynomials, such as addition, subtraction, multiplication, and exponentiation.

The second part of the project is a polynomial calculator that utilizes reverse Polish notation. It allows performing arithmetic operations and displaying the current polynomial on the stack.

The implementation is optimized for efficient dynamic memory allocation, minimizing unnecessary copying and memory allocations. Additionally, the project ensures proper deallocation of all allocated memory, preventing memory leaks. The entire project is documented in Doxygen format.

Pętlik

Tue, 19 Jan 2021 00:00:00 +0000

Pętlik is a small programming language, which syntax is defined by the following grammar with the start symbol Program:

Program → InstructionSequence
InstructionSequence → ε | InstructionSequence Instruction
Instruction → Increment | Repeat
Increment → Variable
Repeat → '(' Variable InstructionSequence ')'
Variable → 'a' | ... | 'z'

Instructions:

Increment: equivalent to ++variable in C, incrementing the variable by 1.

Repeat: equivalent to a C-style while loop:

while (variable > 0) {
 --variable;
 ...
}

The project consist of two components:
