When things aren't happening the way you planned, a source-level debugger can be a great tool in determining what really is going on. Click the "Run to cursor" icon to run your program and pause at the current source code cursor location; Click "Next Step" to step through the code; Click "Add Watch" to monitor variables. Next, make sure you add "using namespace std;" after your includes. The result looks like this: Code::Blocks To compile and run code you need a compiler. You can now run your program. Start Code::Blocks and from nemu File create a new porject:. Note: to pass command-line parameters to your program, go to the "Execute" menu, choose "Parameters" and type in any paramaters you wish to pass. You can double-click on any error to take you to the place in the source code where it occurred. Do this in the fields below the templates.

You can add pre-existing source files one of two ways: Go to the "Project" menu and select "Add to Project" OR Right-click on the project name in the left-hand panel and select "Add to Project". Step 4: Compile.

When things aren't happening the way you planned, a source-level debugger can be a great tool in determining what really is going on. Once your project successfully compiles, the "Compile Progress" dialog box will have a status of "Done".
