How to Solve Programming Problems - Simple Programmer


Debugging and troubleshooting are a normal part of learning to code; it is common to encounter errors. Understanding error types, debugging tools, and different approaches to problem solving can make the process of detecting and fixing bugs less overwhelming. There are several ways to classify debugging issues.

Two common categories are syntax errors and logic errors. These are usually much easier to find and correct. An example would be in C declaring a variable with the identifier count, problem solving and programming, then later referring to it as Count.

C is case sensitive. These types of errors are generally far more difficult to find and solve. Logic errors are usually only discovered when the application behaves in an unusual way for example, gives a result you weren't expecting. Often a logic error occurs when we make a mistake in our programming logic, but our application still compiles and runs.

When we look back through problem solving and programming code we discover the application is indeed doing what we asked of it, however we just asked for the wrong thing by mistake. With complex problems there is typically no one "right" or "wrong" solution; instead you find a range of ideas from less successful to more successful. As you progress in your learning and encounter more complex problems you may have a wide range of viable solutions.

This is problem solving and programming of the art of programming - choosing the best solution for a situation. There are problem solving and programming methods you can use to detect and solve errors in your code. Two approaches new programmers might want to try are walking through the code and experimentation. A helpful option when you are having programming errors is to explain to someone else what your program should be doing.

Walk through each line of code and explain what it does and what should be happening. Often just explaining to problem solving and programming else what the code is supposed to do helps you find out where the error is. This can work with someone who knows nothing about programming, or even an inanimate object see " rubber duck debugging " from the book The Pragmatic Programmer, problem solving and programming.

You might get partway through the explanation and have an "a ha" moment where you see where the error is. Experimenting with code is an important part of learning a programming language.

For many programmers a concept is not fully understood until code has been written, added to, broken, trouble-shooted, debugged, and fixed. This process often reveals new ways of thinking about and solving a problem. For example, without an IDE it is sometimes difficult to find out which line contains a bug.

You can experiment by commenting out the statement problem solving and programming you think contain the problem. If the application compiles and runs, you can try un-commenting out lines until the application no longer compiles.

Once you've found where the bug is at, you can check your syntax for errors, or see if there is a problem with your logic. When experimenting with your code, problem solving and programming, save iterative versions. This allows you to "roll-back". If you make a change down the line that you wish to "undo", you can simply go back to the previous version.

In Visual Studio you can "step" through your code. This allows you to watch as each line runs, problem solving and programming, and the values that your variables are storing at each point in the application's life span.

You can start this process in Visual Studio by just pressing the F11 key. This will highlight the first line of code that will run. Press F11 again to move to the next step. As you move through the code, you can see the values of your variables change in the window at the bottom see screenshot below. A breakpoint is a signal that tells the debugger to temporarily suspend execution of your program at a certain point. You can add one by clicking on the line you want a breakpoint at, then pressing F9.

You'll see a red dot to the left of the line when a breakpoint is active. To turn the breakpoint off, just press F9 again.
