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.
