Definition: The important technique to find and remove the number of errors or bugs or defects in a program is called Debugging. It is a multistep process in software development. It involves identifying the bug, finding the source of the bug and correcting the problem to make the program error-free.
What are debugging techniques?
The debugging process usually consists of the following: examine the error symptoms, identify the cause, and finally fix the error. This process may be quite difficult and require a large amount of work, because of the following reasons: The symptoms may not give clear indications about the cause.

What is the best debugging technique?
Trace-based debugging is traditional and the most common debugging technique used in most debugging tools today. Trace-based debugging is predicated on the concept of breakpoints. A breakpoint is a pausing or stopping point added to the program to examine the state of program execution up until that point.What is debugging and example?

What are advantages of debugging?
Debugging has many benefits such as: It reports an error condition immediately. This allows earlier detection of an error and makes the process of software development stress-free and unproblematic. It also provides maximum useful information of data structures and allows easy interpretation.
What is debugging and code tracing?
Debug and trace enables you to monitor the application for errors and exception with out VS.NET IDE. In Debug mode compiler inserts some debugging code inside the executable. … Tracing is a process about getting information regarding program’s execution. On the other hand debugging is about finding errors in the code.
Why is it called debugging?

What is the difference between testing and debugging?
Testing is the process to find bugs and errors. Debugging is the process to correct the bugs found during testing. It is the process to identify the failure of implemented code. It is the process to give the absolution to code failure.

Debugging Your C# Apps. Debugging refers to the process of trying to track down errors in your programmes. It can also refer to handling potential errors that may occur.
How many types of debugging are there?
There are two types of debugging techniques: reactive debugging and preemptive debugging. Most debugging is reactive — a defect is reported in the application or an error occurs, and the developer tries to find the root cause of the error to fix it.
