break - 流程图

using System;
namespace Loops {
class Program {
static void Main(string[] args) {
/* 局部变量定义 */
int a = 10;
     </span><span class="com">/* while循环执行 */</span><span class="pln">
     </span><span class="kwd">while</span><span class="pln"> </span><span class="pun">(</span><span class="pln">a </span><span class="pun">&lt;</span><span class="pln"> </span><span class="lit">20</span><span class="pun">)</span><span class="pln"> </span><span class="pun">{</span><span class="pln">
        </span><span class="typ">Console</span><span class="pun">.</span><span class="typ">WriteLine</span><span class="pun">(</span><span class="str">"value of a: {0}"</span><span class="pun">,</span><span class="pln"> a</span><span class="pun">);</span><span class="pln">
        a</span><span class="pun">++;</span><span class="pln">
        
        </span><span class="kwd">if</span><span class="pln"> </span><span class="pun">(</span><span class="pln">a </span><span class="pun">&gt;</span><span class="pln"> </span><span class="lit">15</span><span class="pun">)</span><span class="pln"> </span><span class="pun">{</span><span class="pln">
           </span><span class="com">/* 使用 break 语句终止循环 */</span><span class="pln">
           </span><span class="kwd">break</span><span class="pun">;</span><span class="pln">
        </span><span class="pun">}</span><span class="pln">
     </span><span class="pun">}</span><span class="pln">
     </span><span class="typ">Console</span><span class="pun">.</span><span class="typ">ReadLine</span><span class="pun">();</span><span class="pln">
  </span><span class="pun">}</span><span class="pln">

}
} 

编译并执行上述代码时，将生成以下输出-

value of a: 10
value of a: 11
value of a: 12
value of a: 13
