C Do/While 循环


Do/While 循环

The do/while 循环是 while 循环的变体。此循环将执行代码块一次,然后检查条件是否为真,然后只要条件为真,它就会重复循环。

语法

do {
  // 要执行的代码块
}
while (condition);

下面的示例使用 do/while 循环。即使条件为假,循环也始终至少执行一次,因为代码块是在测试条件之前执行的

示例

int i = 0;

do {
  printf("%d\n", i);
  i++;
}
while (i < 5);
自己试试 »

不要忘记增加条件中使用的变量,否则循环将永远不会结束!
