Question

我无法确定如何制作预订学习室的计划 1.在获取菜单的用户输入方面，我是否朝着正确的方向前进？ 2.用户选择一个选项后，如何为其房间选择分配一个新值以显示为打开或不可用？（指针？）

#include <stdio.h>

int main(void)
{
int rm1 = 0;
int rm2 = 0;
int rm3 = 0;
int rm4 = 0;
int rm5 = 0;
int rm6 = 0;
int rm7 = 0;
int rm8 = 0;
int rm9 = 0;
int rm10 = 0;
int input;

while (input != 4)
{

    printf("Welcome to the Study-Room-Reservation System.\n"); /* Asks for user entry */
    printf("Please Select an Option.\n------------------------------------\n");
    printf("1. Reserve study room.\n");
    printf("2. Leave study room.\n");
    printf("3. Check Availability.\n");
    printf("4. Exit.\n");

    scanf("%d", &input);

    if (input == 1)
    {
        printf("Please enter room number you would like to reserve. \n");/* 1. Reserve a room */
        scanf("%d" , &)
    }

    else if (input == 2)
    {
        printf("Please enter room number you would like to exit. \n"); /* 2. Exit a room */
    }

    else if (input == 3)
    {
        printf("The following rooms are available. \n"); /* 3. Show available rooms */
    }

    else
    {
        printf("Invalid Command.\n"); /* Invalid Command */
    }
}



return 0;
}

Answer 1

而不是

int rm1 = 0;
int rm2 = 0;
int rm3 = 0;
.
.

使用数组

int room[10]; //for 10 rooms

然后以类似的方式使用它，

if( room[i] == 0 )
    //room vacant
else if( room[i] == 1 )
    //room occupied
