大家看一下咯!帮帮忙看哪儿出问题了 和楼下贴的应该一样呀 在线等待!!!!我的程序:::::
#include <iostream>
using namespace std;
int main()
{
double n, m;
while (scanf("%lf%lf", &n, &m)==2, n!=0)
{
double w = n<m ? n:m;
double ans=1.0, i;
for (i=1; i<=w; i+=1)
ans *= ((n+m-i+1)/i);
printf("%.0lf\n", ans);
}
return 0;
}
----------------------------
#include < iostream >
using namespace std;
double com (double n,double m)
{
double i;
double result(1);
if ( n >= m - n ){ n = m-n; }
for ( i = m;i >= m-n+1;i-=1 )
{
result *= (i / (i - (m - n)));
}
return result;
}
int main()
{
double n,m;
while (1)
{
scanf("%lf%lf",&n,&m);
if ( n==0 && m==0 ){ break; }
printf("%.0lf\n",com (n,m+n));
}
return 0;
}
