思路:看懂英文就很简单，就是12个数相加求平均数就ok了。

扩展：

C++ 标准输入输出流的控制符

 

 1 #include<stdio.h>
 2 #include<iostream>
 3 #include<string>
 4 #include<iomanip>
 5 using namespace std;
 6 
 7 int main() {
 8     double array[12];
 9     double sum=0.0 ,average=0.0;
10     for (int i = 0; i < 12; i++)
11     {
12         cin >> array[i];
13         sum += array[i];
14     }
15     average = sum / 12;
16     cout<<‘$‘<<fixed<<setprecision(2)<<average<<endl;
17     return 0;
18 }
