6.11. The continue Statement

6.11. continue 语句

A continue statement causes the current iteration of the nearest enclosing loop to terminate. Execution resumes with the evaluation of the condition in the case of a while or do while statement. In a for loop, execution continues by evaluating the expression inside the for header.

continue 语句导致最近的循环语句的当次迭代提前结束。对于 while 和 do while 语句，继续求解循环条件。而对于 for 循环，程序流程接着求解 for 语句头中的 expression 表达式。

For example, the following loop reads the standard input one word at a time. Only words that begin with an underscore will be processed. For any other value, we terminate the current iteration and get the next input:

例如，下面的循环每次从标准输入中读入一个单词，只有以下划线开头的单词才做处理。如果是其他的值，终止当前循环，接着读取下一个单词：

     string inBuf;
     while (cin >> inBuf && !inBuf.empty()) {
             if (inBuf[0] != '_')
                  continue; // get another input
             // still here? process string ...
     }

A continue can appear only inside a for, while, or do while loop, including inside blocks nested inside such loops.

continue 语句只能出现在 for、while 或者 do while 循环中，包括嵌套在这些循环内部的块语句中。
