请教dev-c++下怎么建立工程和编译啊？
搜索了论坛的帖子，没有相关的介绍。这是我看《C primer plus》第9章的例题。书上没有结束工程的建立。用贴图介绍我的过程。
要怎么编译？编译都是单个文件的编译。运行都提示工程未编译。
文件代码：
例9.9：
#include<stdio.h>
#include "hotel.h"
int main(void)
{
int nights;
double hotel_rate;
int code;
while((code=menu())!=QUIT)
{
switch(code)
{
case 1:hotel_rate=HOTEL1;
break;
case 2:hotel_rate=HOTEL2;
break;
case 3:hotel_rate=HOTEL3;
break;
case 4:hotel_rate=HOTEL4;
break;
default:hotel_rate=0.0;
printf("Oops!\n");
break;
}
nights=getnights();
showprice(hotel_rate,nights);
}
printf("Thank you and goodbye.");
return 0;
}
例9.10：
#include<stdio.h>
#include "hotel.h"
int main(void) /*这里应该是menu*/
{
int code,status;
printf("\n%s%s\n",STARS,STARS);
printf("Enter the number of the desired hotel:\n");
printf("1)Fairfield Arms 2)Hotel Olympic\n");
printf("3)Chertworthy Plaza 4)The Stockton\n");
printf("5)quit\n");
printf("%s%s\n",STARS,STARS);
while((status=scanf("%d",&code))!=1||(code<1||code>5))
{
if(status!=1)
scanf("%*s");
printf("Enter an integer from 1 to 5,please.\n");
}
return code;
}
int getnights(void)
{
int nights;
printf("How many nights are needed?");
while(scanf("%d",&nights)!=1)
{
scanf("%*s");
printf("Please enter an integer,such as 2.\n");
}
return nights;
}
void showprice (double rate,int nights)
{
int n;
double total=0.0;
double factor=1.0;
for(n=1;n<=nights;n++,factor*=DISCOUNT)
total+=rate*factor;
printf("The total cost will be $%0.2f.\n",total);
}
hotel.h：
#define QUIT 5
#define HOTEL1 80.00
#define HOTEL2 125.00
#define HOTEL3 155.00
#define HOTEL4 200.00
#define DISCOUNT 0.95
#define STARS "******************"
int menu(void);
int getnights(void);
void showprice(double,int);
