| <h1>Debugging your project</h1> |
| |
| <p>The debugger lets you control the execution of your program by setting |
| breakpoints, suspending executed programs, stepping through your code, and |
| examining the contents of variables.</p> |
| <p>To debug a project:</p> |
| <ol> |
| <li>Click <b>Run > Debug</b>.<p>The Debug dialog box |
| opens.</li> |
| <li>Double-click <b>C++ Local</b>.</li> |
| <li>In the <b>Name</b> box, type <b>Hello World</b>.</li> |
| <p>You can now select this debug launch configuration by name the next time |
| that you debug this project.</p> |
| <li>In the <b>C/C++ Application</b> box, type <b>hello.exe</b>.</li> |
| <li>Click <b>Debug</b>.</li> |
| <p>The debug perspective the hello.exe application window open. |
| The C/C++ editor is repositioned in the perspective.</p> |
| <li>In the left margin of the main.cpp window, double-click to set a |
| breakpoint on:<br> |
| cout << "You just entered"</li> |
| <li>Click <b>Run > Resume</b>.</li> |
| <li>When prompted, type a value other than 'm'.<br> |
| The breakpoint will be hit.</li> |
| <li>In the Variable view, verify that the variable is not 'm'.</li> |
| <li>Click <b>Run > Resume</b>.</li> |
| <li>When prompted, type a value other than 'm'.</li> |
| <p>The breakpoint will be hit.</p> |
| <li>In the <b>Variable</b> view, verify that the variable is not 'm'.</li> |
| <li>In the <b>Variable</b> view, right-click the input variable, and select <b>Change |
| Variable Value</b> and type <b>'m'</b>.</li> |
| <li>Click <b>Run > Resume</b>.</li> |
| <p>The output in the hello.exe application window is:<br> |
| "You just entered m, you need to enter m to exit."<li>Type <b>'m'</b> to end the program.<br> |
| The hello.exe application window closes and the debug session ends. The debug |
| perspective remains open.</li> |
| </ol> |
