代码大致如下： use strict; use warnings; my $total = 0; foreach () { my $temp=function($_); #接收一个函数的返回值 $total += $temp; } print "$total"; 运行的时候提示警告： Use of uninitialized value in addition (+) at..... 就是$total += $temp那一行 请问要怎么改才能不出现这个警告？不要告诉我是注释use warning:wink:
写了一段代码，如下：
#!/usr/bin/perl -w
open (NEWTXT, "C:/Documents and Settings/Administrator/My Documents/新建文本文档.ascii")||die "Cannot open this file:$!";
open (OUTPUT, ">C:/Documents and Settings/Administrator/My Documents/输出.ascii")||die "Cannot open the file match_Yeast_A1:$!";

“Null value was assigned to a property of primitive” 这个错误有由于在长期化中int=null引起的，就是说数值型字段为空时，会抛出这个异常。就是说当读取到数据库有空的时候，无法给源代码中的int赋值，解决要领： 1、使用Integer 2、修改数据库模式，不答应为空。 本文来自ChinaUnix博客，如果查看原文请点：http://blog.chinaunix.net/u3/101592/showart_2016271.html
