运行下面的代码提示说：
Use of uninitialized value $line in split at BLAST_result.pl line 25,
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 (OUTPUT, ">C:/Documents and Settings/Administrator/My Documents/输出.ascii")||die "Cannot open the file match_Yeast_A1:$!";
