Programjavítás

Programjavítás, also known as bug fixing or debugging, is the process of identifying and correcting errors, defects, or unintended behaviors in computer programs. These errors, commonly referred to as bugs, can manifest in various ways, from incorrect calculations and unexpected crashes to security vulnerabilities and performance issues. The primary goal of programjavítás is to ensure that software functions as intended, reliably and efficiently.

The process typically begins with the detection of a bug, which can occur during development, testing, or even after the software has been released to users. Once a bug is identified, developers employ debugging techniques to pinpoint its root cause. This often involves stepping through the code line by line, examining variable values, and analyzing program execution flow. Various tools, such as debuggers, profilers, and logging mechanisms, are used to aid in this analysis.

After the cause of the bug is understood, a solution is implemented. This might involve modifying existing code, adding new code, or sometimes even redesigning a part of the program. Once a fix is applied, rigorous testing is crucial to verify that the bug has been resolved and that no new issues have been introduced. This testing phase is a critical part of the programjavítás cycle to maintain software quality and stability.
