6.5 for语句

一个for语句应该具有如下格式:


for (initialization; condition; update) {
  statements;
}

一个空的for语句(所有工作都在初始化,条件判断,更新子句中完成)应该具有如下格式:


for (initialization; condition; update);

当在for语句的初始化或更新子句中使用逗号时,避免因使用三个以上变量,而导致复杂度提高。若需要,可以在for循环之前(为初始化子句)或for循环末尾(为更新子句)使用单独的语句。

6.6 while语句

一个while语句应该具有如下格式
while (condition) {
  statements;
}

一个空的while语句应该具有如下格式:
while (condition);
6.7 do...while语句

一个do-while语句应该具有如下格式:

do {
  statements;
} while (condition);
