In programming, what is the function of a Debugger?

• A. To execute programs faster
• B. To detect and correct errors in code
• C. To compile high-level language into machine code
• D. To manage resources for applications

Answer: (B)

A debugger is a crucial tool in programming that is primarily designed to detect and correct errors in code. Its main function is to allow developers to identify problems in their programs, commonly referred to as bugs. Once errors are spotted, programmers can analyze the flow of their code and examine variables, which helps in pinpointing the exact location and nature of the issue.

By stepping through the code line by line, developers can watch how values change in real-time and understand how the program behaves. This process is invaluable for ensuring that a program operates as intended and is particularly useful during the development phase of software. Debuggers often provide features such as breakpoints to pause execution at specific points, allowing for careful examination of the code state at that moment.

Other functions such as executing programs faster, compiling high-level languages into machine code, or managing application resources don't directly relate to the primary purpose of a debugger and do not encompass its primary role in the software development lifecycle.
