购买地铁车票的规定如下：乘1-4站3元位；乘5-9站4元位；乘9站以上5元位。 输入人数、站数输出应付款。请编写c语言程序实现

#include<stdio.h>

int main() { int num, station, fee; printf("请输入人数："); scanf("%d",&num); printf("请输入站数："); scanf("%d",&station); if(station>=1 && station<=4) { fee = 3num; } else if(station>=5 && station<=9) { fee = 4num; } else if(station>9) { fee = 5*num; } printf("应付款为：%d元\n",fee); return 0; }
