怎么编写,好难
#include <stdio.h>
int n
{
int sinpleMoney;
if(n<=3)
{
sinpleMoney=13;
printf("”小明单程费用%d\n",sinpleMoney);
}
else{
sinpleMoney=(n-3)*2.3+1+13;
printf("小明单程费用%d\n",sinpleMoney);
}
return 0;
}
int x
extern int n()
{
if(x>5&&x<23)
{
printf("小明单程费用%d\n",sinpleMoney);
}
else{
sinpleMoney*=1.2;
printf("小明上班或下班费用%d\n",sinpleMoney);
}
return 0;
}
int main()
{
int doubleMoney();
doubleMoney=sinpleMoney*2;
printf("小明每天回家费用%d\n",doubleMoney(12));
return 0;
