校园导航系统的数据结构设计通常会涉及到一些基本的数据结构,如数组、链表、树或图,用于存储地点信息、路径规划等。以下是一个简单的示例,使用链表来表示地点和路径:
```c
// 定义地点节点结构体
typedef struct Location {
char name[50]; // 地点名称
int x, y; // 经纬度坐标
struct Location* next; // 指向下一个地点的指针,用于形成链表
} Location;
// 定义一个栈用于路径记录
typedef struct Stack {
Location* top;
int size;
} Stack;
// 添加地点到链表
void addLocation(Location** locations, char* name, int x, int y) {
Location* newLocation = (Location*)malloc(sizeof(Location));
strcpy(newLocation->name, name);
newLocation->x = x;
newLocation->y = y;
newLocation->next = NULL;
if (*locations == NULL) {
*locations = newLocation;
} else {
Location* current = *locations;
while (current->next != NULL) {
current = current->next;
}
current->next = newLocation;
}
}
// 根据起点和终点推算路径
Stack* navigate(Location* start, Location* end, Location** locations) {
Stack* path = (Stack*)malloc(sizeof(Stack));
path->top = NULL;
path->size = 0;
// 路径算法(这里简化为直接添加,实际可能需要搜索算法)
if (start == end) {
push(path, start); // 添加起点到栈
return path;
}
// 假设已有一个路径,添加终点
push(path, end);
return path;
}
// 将地点添加到栈中
void push(Stack* stack, Location* location) {
stack->top = (Location*)malloc(sizeof(Location));
stack->top->name = location->name;
stack->top->x = location->x;
stack->top->y = location->y;
stack->size++;
stack->top->next = NULL;
if (stack->top == stack->top->next) {
stack->top = NULL;
}
}
// 释放内存
void freeLocations(Location** locations) {
Location* current = *locations;
while (current != NULL) {
Location* temp = current;
current = current->next;
free(temp);
}
*locations = NULL;
}

1. 这段代码如何表示校园地图上的节点和路径?
2. 如何根据用户输入的起点和终点查找路径?
3. 在实际应用中,路径算法部分应该如何优化?
