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:
#!/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:
#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。
