What are the 7 steps in order to debug a program?
7 Steps to Debug Efficiently and Effectively
- 1) Always Reproduce the Bug Before You Start Changing Code.
- 2) Understand Stack Traces.
- 3) Write a Test Case that Reproduces the Bug.
- 4) Know Your Error Codes.
- 5) Google! Bing! Duck! Duck! Go!
- 6) Pair Program Your Way Out of It.
- 7) Celebrate Your Fix.
What are the steps of debugging a program?
Here’s the debugging process:
- Reproduce the problem.
- Describe the bug. Try to get as much input from the user to get the exact reason.
- Capture the program snapshot when the bug appears.
- Analyse the snapshot based on the state and action.
- Fix the existing bug, but also check that any new bug does not occur.
How does a debugger help in perfecting a program?
Using the debugger to find errors can greatly reduce the time it takes to perfect a program. The ” power ” of the debugger is that it lets you see the “state” of your program at any point and to advance through your program (“step”) one line at a time in the exact same manner that the code is being executed by the computer.
What are some good questions for a debugging interview?
Commands in windbg. Questions on Critical section, mutex, semaphores. Can we use mutex in single process and how? Working of MSIL and JIT COMPILER. Can a C# code, use c++ code and call kernel functions like createfile. Areas: dot net, oops, operating systems, thread synchronization.
What does it mean to debug in Visual Studio?
Debugging means to run your code step by step in a debugging tool like Visual Studio, to find the exact point where you made a programming mistake. You then understand what corrections you need to make in your code, and debugging tools often allow you to make temporary changes so you can continue running the program.
What does running an app within a debugger mean?
Running an app within a debugger, also called debugging mode, means that the debugger actively monitors everything that’s happening as the program runs. It also allows you to pause the app at any point to examine its state, and to then step through your code line by line to watch every detail as it happens.
