  • HDU 1064 Financial Management

    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. Larry has decided that he needs to grab hold of his financial portfolio and solve his financing problems. The first step is to figure out what’s been going on with his money. Larry has his bank account statements and wants to see how much money he has. Help Larry by writing a program to take his closing balance from each of the past twelve months and calculate his average account balance.
     
    Input
    The input will be twelve lines. Each line will contain the closing balance of his bank account for a particular month. Each number will be positive and displayed to the penny. No dollar sign will be included.
     
    Output
    The output will be a single number, the average (mean) of the closing balances for the twelve months. It will be rounded to the nearest penny, preceded immediately by a dollar sign, and followed by the end-of-line. There will be no other spaces or characters in the output.
     
    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
     
    题意:输入12个月每月月末银行存款余额,输出这12个实数的平均值。
    分析:循环输入,输入时累加,注意输出时要求的格式。
    AC源代码(C语言):
    #include<stdio.h>
    int main()
    {
        int i;
    double a,s; s=0; for(i=1;i<=12;i++) { scanf("%lf",&a); s+=a; } printf("$%.2lf\n",s/12); return 0; }
