What is debugging and why do you need it
When you're coding, debugging is the process of finding and removing errors from your code. Without debugging, your code may not run correctly, or may not run at all. There are many different types of errors that can occur in code, and debuggers help you find and fix them so that your code runs smoothly. In some cases, debuggers can even automatically fix errors for you. While it's important to know how to debug your own code, it's also important that you use a debugger when working with someone else's code. This way, you can catch any errors that they may have missed. Debugging is an essential part of coding, and it's something that every coder needs to know how to do.
Setting a breakpoint in your code
In software development, a breakpoint is an intentional stopping or pausing place in a codebase which is used for debugging purposes. When a breakpoint is reached during execution, the debugger typically suspends the execution of the program at that point, so that the programmer can examine the current state of the system and determine why the breakpoint was reached. There are many different types of breakpoints which can be set, each with its own specific purpose. For example, conditional breakpoints allow the programmer to specify that execution should only be suspended if certain conditions are met. This can be useful when trying to track down a bug which only occurs under certain circumstances. Another type of breakpoint is a log point, which allows the programmer to log information about the current state of the system without suspending execution. This can be useful for gathering information about how a system is behaving without interrupting its normal operation. There are many other types of breakpoints as well, each with its own specific use cases. In general, breakpoints are an essential tool for any software developer and can make debugging much easier.
Stepping through your code line by line
Debugging can be a frustrating process, especially when you're not sure where the problem is. One helpful technique is to step through your code line by line, running it in your head (or in a debugger) and keeping track of the values of each variable. This can help you to narrow down the source of the problem and find a solution more quickly. Of course, this technique is only effective if you have a clear understanding of your code. If you're not sure what a particular line of code is supposed to do, stepping through it won't do you much good. In these cases, it's often better to look at the bigger picture and try to identify the general area where the problem is occurring. Once you've found the general area, you can then zoom in and start stepping through your code line by line.
Investigating variable values
In mathematics, a variable is a value that can change. For example, in the equation "x + 3 = 5", the variable is "x" because it can represent different numbers (2, 3, 4, etc.). In order to solve an equation, we need to find the value of the variable that makes the equation true. There are a variety of methods that can be used to investigate the value of a variable. The most common approach is to plug in different values and see which one gives the correct answer. However, this method can be time-consuming and may not always be possible. Another approach is to use algebraic methods to solve for the variable. This can be more efficient than trial and error, but it requires a certain level of mathematical sophistication. Ultimately, the best method for investigating the value of a variable will depend on the equation in question and the abilities of the person solving it.
Debugging is the process of finding and fixing errors in your code. Â Errors can cause your program to crash, behave unexpectedly, or produce incorrect results. Â Debugging is an essential part of software development, and all programmers should be familiar with it
-One way to debug your code is by setting breakpoints. A breakpoint is a point in your code where the debugger will pause execution so that you can investigate the state of your program. Â To set a breakpoint, open the source file in question and place the cursor on the line where you want to stop execution. Â Then, go to the Debug menu and select Toggle Breakpoint. The debugger will now pause execution at that point
-To step through your code line by line, use the Step Over command (F10) or Step Into command (F11). The Step Over command will execute one line of code and then pause again; whereas, Step Into will execute one line of code and then enter into that function for further examination. You can also use these commands to skip over entire functions or blocks of code. Variable values are shown in a separate panel called the Variable Watch window. You can add variables to this window by selecting them from the Variables list on the left side of the window or by typing their names into the text box at the top of the window. The console panel also provides valuable information about your program’s state. It shows messages from Python as well as any errors that occur while debugging
