CodeBlocks is surprisingly versatile, and in my opinion, much better than the Visual Studio suite. The mother site of CodeBlocks is www. Click "Download the binary release".
Select your operating platform e. Download the installer with GCC Compiler, e. Verify the Compiler's and Debugger's Path: It shall be set to the "MinGW" sub-directory of the CodeBlocks installation directory, for example, suppose that CodeBlocks is installed in " c: Similarly, check the debugger's path. I encountered problem running debugger with CodeBlocks I resolved by installing the latast MinGW gcc 4.
Other than the few-line toy programs, you shall create a project for each of your application. A project contains related files such as source codes, header files, and relevant resources. Also, under CodeBlocks, you can only debug your program under a project - single-file program in previous section debugging is not supported. You can create more projects. However, the "Build" and "Run" commands are always apply to the active project, which is shown in bold. To activate a project: Although a project may contain many source files, there can only be one main function among all the source files.
That is, you cannot keep two toy programs each having a main function in one project you will get the error "multiple definition of 'main'" when you try to build the project. You need to create one project for each toy program. Codeblock, nonetheless, allow you to add files or remove files from a project.
The removed files are not deleted and remain in the folder. We could use this feature to write many toy programs under one project. The procedures are as follows:.
In brief, use the "Add File" and "Remove File" to place your desired toy program file with the main function under the active project. You can then "Build" the project and "Run" your toy program. A previous program is still running. You need to terminate the program by closing the output console window. Check that you have a main function in your function. Check your spelling of main! Check your scanf function. Able to use a graphics debugger to debug program is crucial in programming.
It could save you countless of hours guessing on what went wrong. It outputs "The Factorial of 20 is " - a negative number?! Set an initial breakpoint at main function by clicking on the "left-margin" right-side of the line number of the line containing main.
A red circle appears indicating a breakpoint has been set at that line. A breakpoint suspends program execution for you to examine the internal states. From "Debug" menu, select "Start F8 ". The program begins execution but suspends its execution at the breakpoint, i. An yellow arrow as shown in the diagram appears and points at the main , indicating this is the next statement to be executed.
Click the "Debugging Windows" button on the "Debug" toolbar and select "Watches" to enable the "Watch" pane. You could also do it from the "Debug" menu. Click the "Next line" button on the "Debug" toolbar to single-step thru your program. At each of the step, you could examine the internal state of your program, such as the value of the variables in the "Watches" pane , the outputs produced by your program in the console , etc. Single-stepping thru the program and watching the values of the variables and the outputs produced is the ultimate mean in debugging programs - because it is exactly how the computer runs your program!
As mentioned, a breakpoint suspends program execution and let you examine the internal states of the program. To set a breakpoint on a particular line, click the left-margin of that line or select "Toggle Breakpoint F5 " from "Debug" menu. The "Continue" resumes the program execution, up to the next breakpoint, or till the end of the program. Single-stepping thru a loop with a large count is time-consuming. You could set a breakpoint at the statement immediately outside the loop e.
Alternatively, you can place the cursor on a particular line, right-click and select "Run-To-Cursor" to resume execution up to this line. The "Stop" ends the debugging session. Always terminate your current debugging session using "Stop" or "Continue" till the end of the program.
I can's stress more that mastering the use of debugger is crucial in programming. Explore the features provided by the debuggers. To debug a function , you need to use "Step-Into" to step into the first statement of the function. You could use "Step-Out" to return to the caller, anywhere within the function. Alternatively, you can set a breakpoint inside a function.
