<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  &gt; 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>
  &nbsp;cout &lt;&lt; &quot;You just entered&quot;</li>
  <li>Click <b>Run  &gt; 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  &gt; 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  &gt; Resume</b>.</li>
  <p>The output in the hello.exe application window is:<br>
&nbsp;&quot;You just entered m, you need to enter m to exit.&quot;<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>

debug conceptual topics.</p>
