It is also used to finish each clause of a <a href="switch.html">switch</a> statement, keeping the program from "falling through" to the next case in the code. An example:</p> <pre class="example-code"> while( x < 100 ) { if( x < 0 ) break; cout << x << endl; x++; } </pre> <p>A given break statement will break out of only the closest loop, no further. If you have a triply-nested for loop, for example, you might want to include extra logic or a <a href="goto.html">goto</a> statement to break out of the loop.</p> <div class="related-name-format"> Related topics: </div> <div class="related-content"> <a href="continue.html">continue</a><br> <a href="do.html">do</a><br> <a href="for.html">for</a><br> <a href="goto.html">goto</a><br> <a href="switch.html">switch</a><br> <a href="while.html">while</a> </div> </div> </td> </tr> </table></body></html>⌨️ 快捷键说明
