Line 5 should probably read as:
第5行应该读作:
read array[$i]
${array[$i]}, which is what you have at present, will output the value of the element of the array with the subscript $i. The read command reads user input into a specified variable, so you need to specify the variable name.
$ {array [$ i]},就是你现在所拥有的,将输出带有下标$ i的数组元素的值。 read命令将用户输入读入指定的变量,因此您需要指定变量名称。

you could also write
你也可以写
array=()
for ((i=0; i<n; i++)); do
read -p "Enter number $i "
array+=($REPLY)
done
