要求:编写一个脚本，该脚本提示用户输入一些整数，然后通过程序控制分别计算出这些整数中的
奇数之和与偶数之和，并输出。
我的思路是结合数组来实现:
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28
29
30

#!/bin/bash
#charpter_8-9
#trap 'echo "Before executing the line: $LINENO,sum2=$sum2,sum1=$sum1"' DEBUG
declare
-a array1
echo
"Please input some integer numbers separated by SPACE:"
read
-a array1
echo
The length of array1 is:
"${#array1[@]}"
let
max=
"${#array1[@]}"
let
sum_odd=0
let
sum_even=0
fun()
{
for
((i=0;i<$max;i++))
do
let
"temp=array1[i]%2"
if
[
"$temp"
-
eq
"0"
]
then
let
sum_even+=array1[i]
else
let
sum_odd+=array1[i]
fi
done
echo
"奇数之和:sum_odd=$sum_odd"
echo
"偶数之和:sum_even=$sum_even"
}
fun
|
执行测试:
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14

#测试一
[root@localhost charpter8]
# sh 8-9
Please input some integer numbers separated by SPACE:
12 23 34 45 56 67 78
The length of array1 is: 7
奇数之和:sum_odd=135
偶数之和:sum_even=180
#测试二
[root@localhost charpter8]
# sh 8-9
Please input some integer numbers separated by SPACE:
11 12 21 22 32 33
The length of array1 is: 6
奇数之和:sum_odd=65
偶数之和:sum_even=66

可以看到，脚本可以正常获取想要的结果。
