$ perl -e 'print length "很好很强大", "\n"' 15 怎么是一个字占了3字节？ printf %10s 遇到中英文混合的时候就乱套了 [code] #!/usr/bin/perl $a="henhao"; $b="很好"; printf "%-10s%-10s\n", $a,$a; printf "%-10s%-10s\n", "z",$b; printf "%-10s%-10s\n", $b,$a; $ $ $ perl b.pl henhao henhao z 很好 很好 henhao #这里没对齐 [/code]

我有一个很大的数据文件，是以^G来分割的，其中有一个字段超大，用awk总是报awk: record '.......' too long的错误，请问有什么办法可以规避这个问题。 谢谢！！！
If a method returns an array which can be empty, do not allow it to return null. Instead, return a zero-length array. This simplifies the client, since they never have to check for null values. Example import java.util.*; public class StockPortfolio { //..elided /** * A field is implemented internally as a Collection, * but offered to the user of this class as an Array. * This array is n...
Hi, I hit a problem with the length of username on solaris 9/10. finally I worked around the problem by truncating the username to 8-characters.
