如何使用数组值作为哈希中的键?
问题描述:
@func是包含名称的数组.我想为每个名称分配值,如下所示,但它确实起作用.
@func is an array containg names. I want to assign values to each name as below, but it does seem to work.
for ($i=0;$i<10; $i++)
{
$hash{'$func[$i]'}= $i;
}
print $hash{'$func[0]'};
我收到如下错误:
I get an error as below:
Use of uninitialized value in print at D:/eclipse/workspace/Pgm1.pl line 47, <FILE1> line 57.
请帮忙.
Please help.
Thanks in advance.
