c语言医院路线导航代码

以下是一个简单的 C 语言代码示例，可以用于医院的路线导航：

#include <stdio.h>
#include <string.h>

#define MAX_HOSPITALS 100
#define MAX_NAME_LENGTH 50
#define MAX_DESCRIPTION_LENGTH 100

typedef struct {
    char name[MAX_NAME_LENGTH];
    char description[MAX_DESCRIPTION_LENGTH];
    int floor;
    int room;
} Hospital;

typedef struct {
    Hospital start;
    Hospital end;
    float distance;
} Path;

void print_hospital(Hospital h) {
    printf("%s\n", h.name);
    printf("Description: %s\n", h.description);
    printf("Floor: %d\n", h.floor);
    printf("Room: %d\n", h.room);
}

void print_path(Path p) {
    printf("Start: ");
    print_hospital(p.start);
    printf("End: ");
    print_hospital(p.end);
    printf("Distance: %.2f meters\n", p.distance);
}

float distance_between_hospitals(Hospital h1, Hospital h2) {
    // Here we are just making up a formula for calculating distance between hospitals
    float x_diff = h1.floor - h2.floor;
    float y_diff = h1.room - h2.room;
    return sqrt(x_diff * x_diff + y_diff * y_diff) * 10; // Multiply by 10 to get distance in meters
}

int main() {
    Hospital hospitals[MAX_HOSPITALS];
    int num_hospitals = 0;

    // Add some example hospitals
    Hospital h1 = {"St. Mary's Hospital", "General hospital", 2, 205};
    hospitals[num_hospitals++] = h1;

    Hospital h2 = {"City Hospital", "Specialized in emergency care", 1, 102};
    hospitals[num_hospitals++] = h2;

    Hospital h3 = {"University Hospital", "Research hospital", 3, 306};
    hospitals[num_hospitals++] = h3;

    // Ask user for start and end hospitals
    printf("Enter start hospital name: ");
    char start_input[MAX_NAME_LENGTH];
    fgets(start_input, MAX_NAME_LENGTH, stdin);
    start_input[strcspn(start_input, "\n")] = '\0'; // Remove newline character

    printf("Enter end hospital name: ");
    char end_input[MAX_NAME_LENGTH];
    fgets(end_input, MAX_NAME_LENGTH, stdin);
    end_input[strcspn(end_input, "\n")] = '\0'; // Remove newline character

    // Search for start and end hospitals
    Hospital start_hospital, end_hospital;
    int found_start = 0, found_end = 0;
    for (int i = 0; i < num_hospitals; i++) {
        if (!found_start && strcmp(start_input, hospitals[i].name) == 0) {
            start_hospital = hospitals[i];
            found_start = 1;
        }
        if (!found_end && strcmp(end_input, hospitals[i].name) == 0) {
            end_hospital = hospitals[i];
            found_end = 1;
        }
        if (found_start && found_end) {
            break;
        }
    }

    // If start or end hospital not found, print error message
    if (!found_start) {
        printf("Start hospital not found!\n");
        return 0;
    }
    if (!found_end) {
        printf("End hospital not found!\n");
        return 0;
    }

    // Calculate distance between start and end hospitals
    float distance = distance_between_hospitals(start_hospital, end_hospital);

    // Print path information
    Path path = {start_hospital, end_hospital, distance};
    print_path(path);

    return 0;
}

该示例中，我们定义了一个 `Hospital` 结构体，其中包含了医院的名称、描述、楼层和房间号。我们还定义了一个 `Path` 结构体，其中包含了起始医院、目标医院和距离。我们使用两个数组来存储多个医院的信息，并通过循环和字符串比较来查找用户输入的起始医院和目标医院。如果找到了对应的医院，我们将计算它们之间的距离，并打印出路径信息。如果没有找到某个医院，则会打印出相应的错误信息。在此示例中，我们只是简单地使用了一个距离计算公式来计算医院之间的距离，实际应用中可能需要更复杂的算法来计算路径。
