int main(){
    double sum = 0,temp;
    for(int i = 0;i<12;i++){
        cin>>temp;
        sum += temp;
    }
    sum /= 12;

Problem Description
Larry graduated this year and finally has a job. He’s making a lot of money, but somehow never seems to have enough. 
拉里今年毕业,如今最终有一份工作。

他挣了非常多钱。可是非常奇怪,似乎钱永远都不够用。

Larry has decided that he needs to grab hold of his financial portfolio and solve his financing problems. 
拉里已经决定,他必须抓住他的金融投资组合和解决融资问题。(通俗讲就是,学会用钱)
The first step is to figure out what’s been going on with his money.
第一步:确定全部用掉的的钱。用来干了什么。
 Larry has his bank account statements and wants to see how much money he has.
拉里有他的银行账户报表,于是他想看看他还有多少钱。
 Help Larry by writing a program to take his closing balance from each of the past twelve months and calculate his average account balance.
 写一个程序来帮助拉里,从如今開始,计算过去12个月的平均剩余金额(不是连续的自然月)。

Input
The input will be twelve lines. Each line will contain the closing balance of his bank account for a particular month.
输入语句有12行。每一行都表示特定的月份,且都是当月月底的剩余金额。
 Each number will be positive and displayed to the penny. No dollar sign will be included.
 每一行由两部分组成,一个正数,一个没有显示的美元符。可是没有美元符号显示。

Output
The output will be a single number, the average (mean) of the closing balances for the twelve months. 
输出仅仅有一行,表示12个月的平均值。
It will be rounded to the nearest penny, preceded immediately by a dollar sign, and followed by the end-of-line. 
每个数据都是美元值,能够精确到份。最前边有一个美元符,最后到行尾。
There will be no other spaces or characters in the output.
 输出行没有空格。

Sample Input
100.00 489.12 12454.12 1234.10 823.05 109.20 5.27 1542.25 839.18 83.99 1295.01 1.75
 

Sample Output
$1581.42
