C++编写程序输出1~100之间各位数乘积大于各位数的和的数，要求判断各位数乘积大于各位数的和用函数表示

Answer 1

# include <stdio.h>
int f(int n)
{
sum1=1;
sum2=0;
for(i=n;i>0;i=i/10)
{
i=i%10;
sum1=sum1*i;
sum2=sum2+i;
}
if(sum1>sum2)
return 1;
else
return 0;
}
int main()
{
int i;
for(i=1;i<=100;i++)
if(f(i))
printf("%d\n",i);
return 0;
}

Answer 2

#include<iostream>
using namespace std;
int fun(int n)
{
int s = 0;
int t = 1;
while(n > 0)
{
s += (n % 10);
t *= (n % 10);
n /= 10;
}
return t > s;
}
int main()
{
int i;
for(i = 0; i <= 100; i++)
{
if(fun(i))
cout<<i<<" ";
}
return 0;
}
