Understand what debugging is and debugging meaning in Hindi

Debugging Meaning in Hindi

In Hindi, debugging is referred to as 'डीबगिंग'. It's a process that involves identifying and removing errors or 'bugs' from a computer program. Let's break down the meaning of debugging in Hindi:

• डीबगिंग (Debugging): यह एक प्रक्रिया है जिसमें कंप्यूटर प्रोग्राम से त्रुटियां या 'बग' की पहचान और उन्हें हटाने का काम होता है।

• बग (Bug): बग एक त्रुटि होती है जो प्रोग्राम में अनपेक्षित परिणाम का कारण बनती है।

• डीबगर (Debugger): डीबगर एक सॉफ्टवेयर उपकरण होता है जिसका उपयोग डीबगिंग के लिए किया जाता है।

What is Debugging?

Debugging refers to an important part of programming whereby we locate, separate and rectify bugs in computer codes. It's almost like being a code detective where you are looking for who or what caused the problem.

Back in 1940s, Grace Hopper made popular the term 'debugging' due to a moth that had disrupted her computer. Since then, it has been used to mean fixing issues with codes.

Debugging is not only about correcting errors that hinder the execution of your program; it also entails streamlining your code for better performance and normal operation. To debug effectively requires having an in-depth understanding of the program and its challenge at hand.

Debugging Techniques

Debugging is a crucial technique that cannot be detached from programming. It's an exercise done in order to discover the bugs, identify their location and fix them. These are some debugging techniques employed by programmers:

1. Print Debugging: This can be seen as one of the most basic types of debugging. It includes placing print statements in your code that produce output of variable values or even flows of execution. Through this, one is able to appreciate where he or she has gone wrong with the code. For instance, if you want to know why a function doesn't return what was expected you might insert a print statement here to display both input and output values for the function.

2. Breakpoints: Breakpoints are more complex forms of debugging. They allow program execution to stop at some point so that variable values at that moment can be examined. This is very useful in understanding how your program is at different stages of its running time. A majority of integrated development environments (IDEs) and debuggers provide users with easy-to-use mechanisms for defining and handling breakpoints.

3. Stepping: Stepping is a method of your program following one line at a time. This can be very useful in understanding the flow of your program and exactly when things start to go wrong. Normally there are three types of stepping actions: step into, step over and step out. Step into will move to the next function call, while step over will go to the next line in the current function and step out will complete the current function and move on to the next line in the calling function.

4. Watch Expressions: Watch expressions allow you to monitor specific variable values. When these variables change values, then debuggers know about it. This can be helpful when you want to check on a variable’s status that you think could be causing problems too.

5. Call Stack Inspection: It is possible to inspect the call stack at any point within your program using this technique. This is useful for understanding which series of functions were called prior reaching a particular stage in your code. The call stack shows you what functions have been called so far before getting where you are now, and what arguments were passed to each of those functions.

Debugging in Action: A Case Study

Think of a simple Python program that can calculate the factorial of a number. but, there's a bug in this program. We are going to debug this program.

Below is the code with bugs:

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n)

For instance, when we try to compute the factorial of 5 using this function, the program goes into an infinite loop. This is our bug. Now let's debug it.

We use print debugging first to study the flow of the program. We put in a print statement which will display n value at each function call:

def factorial(n):
    print(f"Calculating factorial({n})")
    if n == 0:
        return 1
    else:
        return n * factorial(n)

When we execute the program now, it prints "Calculating factorial(5)" repeatedly. It means that between function calls n remains constant and for these reasons there occurs an infinite loop.

Next we break at a point after printing a statement while running our code. When we examine call stacks we see that factorials keeps on calling with same argument.

Lately, we realized our mistake that instead of decreasing ‘n’ by 1 during recursive call to ‘factorial’. Below is how corrected code looks like:

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n - 1)

Now if you compute 5 factorial the result will be 120.

Conclusion

I hope this blog post has been helpful in demystifying debugging and its meaning in Hindi. Debugging process is a vital aspect of programming that can greatly improve your coding skills. You are able to write the best code possible by grasping the concept of debugging and acquiring knowledge about different ways to debug.

Remember, debugging is not just about fixing errors, it’s about understanding your code better and improving its quality. So, keep practising, keep debugging, and keep getting better. Happy coding!

Finally, i would like to say “समझना महत्वपूर्ण है, लेकिन अभ्यास करना और भी महत्वपूर्ण है।” (Understanding is important but practicing even more.)
