What are debugging techniques?
Reproduce the bug or problem. Explain the bug using input from the user. Try to get all the variable values and state of the program when the bug appears. Analyze the bug and find the cause of the bug. Fix the bug and check all the causes of new bugs.
What is debugger and how it works?
The simplified answer is: When you put a break-point into the program, the debugger replaces your code at that point with a int3 instruction which is a software interrupt. As an effect the program is suspended and the debugger is called.

What is the first step of debugging?
The basic steps in debugging are: Recognize that a bug exists. Isolate the source of the bug. Identify the cause of the bug.
What is a debugging tool?
Debugging tools (called debuggers) are used to identify coding errors at various development stages. They are used to reproduce the conditions in which error has occurred, then examine the program state at that time and locate the cause.
Is debugging safe?
Basically, leaving USB debugging enabled keeps the device exposed when it’s plugged in over USB. Under most circumstances, this isn’t a problem—if you’re plugging the phone into your personal computer or you have the intention of using the debugging bridge, then it makes sense to leave it enabled all the time.
How do I debug faster?

Why do we use debugger?
The main use of a debugger is to run the target program under controlled conditions that permit the programmer to track its operations in progress and monitor changes in computer resources (most often memory areas used by the target program or the computer’s operating system) that may indicate malfunctioning code.
What does debug command do?
The debug command displays information about the Cisco device operations, generated or received traffic, and any error messages. The information are provided in real-time until the user disables debugging or the device is restarted.
