uva 147 Dollars

 Dollars 

New Zealand currency consists of $100, $50, $20, $10, and $5 notes and $2, $1, 50c, 20c, 10c and 5c coins. Write a program that will determine, for any given amount, in how many ways that amount may be made up. Changing the order of listing does not increase the count. Thus 20c may be made up in 4 ways: 1  20c, 2 10c, 10c+2  5c, and 4  5c.

Input

Input will consist of a series of real numbers no greater than $300.00 each on a separate line. Each amount will be valid, that is will be a multiple of 5c. The file will be terminated by a line containing zero (0.00).

Output

Output will consist of a line for each of the amounts in the input, each line consisting of the amount of money (with two decimal places and right justified in a field of width 6), followed by the number of ways in which that amount may be made up, right justified in a field of width 17.

Sample input

0.20
2.00
0.00

Sample output

  0.20                4
  2.00              293

和上一道模板题差不多，因为有小数，但是最多两位小数，所以所有数据直接变成20倍计算。注意输出格式。

题意：11种钱币，指定钱的数额，输出最大组成数。

附上代码：

#include <iostream>
#include <cstdio>
#include <cstring>
using namespace std;
long long dp[6005];
int main()
{
    int i,j,m;
    int coin[11]= {1,2,4,10,20,40,100,200,400,1000,2000};
    memset(dp,0,sizeof(dp));
    dp[0]=1;
    for(i=0; i<11; i++)
        for(j=coin[i]; j<=6000; j++)
            dp[j]+=dp[j-coin[i]];
    double n;
    while(~scanf("%lf",&n))
    {
        m=(int)(n*20);
        if(m==0) break;
        printf("%6.2lf%17lld
",n,dp[m]);
    }
    return 0;
}
