How does a C++ debugger work?
Debuggers change the loaded image of the executable in memory and insert the “int 3″ instruction at runtime. However, this would only be used for the “run to current line option”. Show activity on this post. Single stepping is implemented at (assembler) code level not at C++ level.
What is debugging in C++ with example?
Debugging is a methodical process of finding and reducing the number of bugs (or defects) in a computer program, thus making it behave as originally expected. There are two main types of errors that need debugging: ▶ Compile-time: These occur due to misuse of language constructs, such as syntax errors.
What is visual debugging?
Visual debugging provides the Visual Debug view for you to interact with your COBOL or PL/I debug session. With this view, you can visualize the stack trace, set breakpoints, and run to a selected call path. Notes: Visual debugging is not available in IBM® Debug for z Systems™.
How do I debug code in Visual Studio code?

What comes first testing or debugging?
Testing is composed of validation and verification of software. While debugging process seeks to match symptom with cause, by that it leads to the error correction. Testing is initiated after the code is written. Debugging commences with the execution of a test case.
What is the purpose of a debugger?
A debugger is a software tool that can help the software development process by identifying coding errors at various stages of the operating system or application development. Some debuggers will analyze a test run to see what lines of code were not executed.
