@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.
