Program Analysis is the process of evaluating computer programs to understand their behavior, performance, and correctness. It involves examining the code to identify potential errors, inefficiencies, or security vulnerabilities. This analysis can be done statically, without executing the program, or dynamically, while the program is running. The goal of Program Analysis is to improve software quality and reliability. Techniques used in this field include static analysis, which checks code for issues before execution, and dynamic analysis, which monitors the program during its operation. By applying these methods, developers can create more robust and efficient software.
