Dev C++ is a free and open source integrated development environment (IDE) for C and C++ programming languages. It comes with a built-in debugger that can help you find and fix errors in your code. In this article, we will show you how to use the debugger in Dev C++ to resolve run-time errors in your C code.
Setting Up the Debugger
Before you can use the debugger, you need to make sure that your project is configured correctly. Follow these steps:
Open your project in Dev C++.
Go to Project > Project Options > Compiler > Linker.
Select the base compiler as \"TDM-GCC 4.9.2 64 bit Debug\" or a similar option that has \"Debug\" in its name.
Set the \"Generate debugging information\" option to \"Yes\".
Make sure you are not using any optimization options (such as -O2 or -O3) or strip option (-s) in the Parameters tab.
Click OK to save the changes.
Do a full rebuild of your project by pressing Ctrl-F11 or choosing Execute > Rebuild.
Using the Debugger
Now you are ready to launch the debugger and find the errors in your code. Follow these steps:
Set one or more breakpoints in your code where you want the debugger to stop. To set a breakpoint on a line, click on the gray band on the left of the line, or press Ctrl-F5. A red dot will appear to indicate a breakpoint.
Start the debugger by pressing F8 or choosing Execute > Debug. The program will run until it reaches the first breakpoint, then it will pause and show you the current state of the program.
You can use the buttons on the toolbar or the keyboard shortcuts to step through the code, enter function calls, or continue execution until the next breakpoint. Here are some common commands:
Step into: Shift-F7 or button with arrow pointing down. This will execute the current line and enter any function call on that line.
Next step: F7 or button with arrow pointing right. This will execute the current line and skip any function call on that line.
Continue: Ctrl-F7 or button with arrow pointing right and down. This will resume execution until the next breakpoint or the end of the program.
You can inspect the values of variables and expressions by hovering your mouse over them, or by adding them to the watch list. To add a watch, press F4 or click on the button with an eye icon, then type the expression you want to watch. The watch list will show you the values of your expressions at each step of the program.
You can also view other information about your program, such as call stack, registers, memory, threads, etc., by using the tabs on the bottom panel of Dev C++.
To stop debugging, press Shift-F8 or click on the button with a red square icon.
In this article, we have learned how to use the debugger in Dev C++ to find and fix run-time errors in our C code. Debugging is an essential skill for any programmer, and Dev C++ provides a simple and powerful tool for debugging. We hope this article has helped you learn how to debug your code using Dev C++.
