| 1 | + | REPEAT..UNTIL循环 (原作者: Tao Yue, 状态: 未更改) | |
| 2 | + | ||
| 3 | + | 先循环后判断： | |
| 4 | + | ||
| 5 | + | ``` pascal | |
| 6 | + | repeat | |
| 7 | + | 语句1; | |
| 8 | + | 语句 | |
| 9 | + | until 逻辑表达式; | |
| 10 | + | ``` | |
| 11 | + | ||
| 12 | + | 在repeat循环中，复合语句是内置的，因此，你不需要使用begin-end。另外，直至表达式值为真退出循环。 | |
| 13 | + | ||
| 14 | + | `REPEAT`循环被称之为先循环后判断，任何情况下，循环至少执行一次。 | |
| 15 | + | ||
| 16 | + | ``` pascal | |
| 17 | + | var | |
| 18 | + | sum,count : integer; | |
| 19 | + | ||
| 20 | + | begin | |
| 21 | + | sum := 0; | |
| 22 | + | count := 0; | |
| 23 | + | ||
| 24 | + | repeat | |
| 25 | + | count := count + 1; | |
| 26 | + | sum := sum + count | |
| 27 | + | until (count >= 100); | |
| 28 | + | ||
| 29 | + | writeln('sum=', sum); | |
| 30 | + | end. | |
