（for述句）韩信点兵中的最大值问题

#include <stdio.h>
int main()
{


int max;
printf("MAX = ");
scanf("%d", &max);
int number;
int answer = 0;
for (number = max;number >= 1 && answer == 0; --number)
{
    if (number%3 == 2 && number%5 == 3 && number%7 == 2)
    {
        answer = number;
    }
}
if (answer != 0)
{
  printf("%d\n",answer) ;
}

return 0;
}
