GDB, which stands for GNU Debugger, is a software tool widely used in computer programming for debugging programs written in various languages. It is a free and open-source debugger developed as part of the GNU project and is available for various operating systems, including Unix-like systems and Windows.
As a debugger, GDB helps programmers identify and correct errors, also known as bugs, in their programs. It allows for detailed examination of program execution, allowing users to monitor variables, stack traces, and control flow. GDB operates by attaching itself to a running program or by analyzing a core dump, allowing the programmer to interactively explore and modify the program's state during runtime.
GDB offers a wide range of features, including breakpoints, watchpoints, and single-stepping through code. These features enable programmers to pause program execution at specific points, observe memory changes, and execute code line by line, respectively. GDB also provides support for examining and manipulating data structures, examining registers, and performing remote debugging, allowing debugging of programs running on different machines.
In summary, GDB is a powerful and versatile debugging tool used by programmers to find and troubleshoot errors in their programs. Its comprehensive set of features and platform compatibility make it an essential tool for software development across various programming languages and operating systems.
