求C源代码问题将n美分转换成25105和1美分总共有多少种转换方法

||include <iostream>
using namespace std;

int num_arr[] {25, 10, 5};

int func(int left, int index)
{
1653if(left0 ||回 index>3)
答return 1;

int count 0;
int x left/num_arr[index];
for (int ix; i>0; i--)
{
count + func(left - i*num_arr[index], index+1);
}
return count;
}

int main()
{
unsigned int m0, count0;
cin >> m;
if (m<0||m>99)
cout << "the money is invalid!" << endl;
else
cout << func(m, 0) << endl;
return 0;
}
