用c语言代码实现图算法系统,要求有交互式页面

很好,这是一个非常有挑战性的项目。以下是一个简单的示例代码,帮助你开始:
```
#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
#include <string.h>
// 定义图的结构体
typedef struct Graph {
int **matrix;
int numVertices;
} Graph;
// 创建图
Graph *createGraph(int numVertices) {
Graph *graph = (Graph*)malloc(sizeof(Graph));
graph->numVertices = numVertices;
graph->matrix = (int**)malloc(numVertices * sizeof(int*));
for (int i = 0; i < numVertices; i++) {
graph->matrix[i] = (int*)malloc(numVertices * sizeof(int));
memset(graph->matrix[i], 0, numVertices * sizeof(int));
}
return graph;
}
// 添加边
void addEdge(Graph *graph, int src, int dest, int weight) {
graph->matrix[src][dest] = weight;
}
// 删除边
void removeEdge(Graph *graph, int src, int dest) {
graph->matrix[src][dest] = 0;
}
// 判断边是否存在
bool isEdge(Graph *graph, int src, int dest) {
return graph->matrix[src][dest] != 0;
}
// 交互式页面
void interactivePage() {
int numVertices, option, src, dest, weight;
printf("请输入节点数:");
scanf("%d", &numVertices);
Graph *graph = createGraph(numVertices);
do {
printf("请选择操作:\n");
printf("1. 添加边\n");
printf("2. 删除边\n");
printf("3. 判断边是否存在\n");
printf("4. 退出\n");
scanf("%d", &option);
switch (option) {
case 1:
printf("请输入源节点和目标节点的编号以及边权重(用空格分隔):");
scanf("%d %d %d", &src, &dest, &weight);
addEdge(graph, src, dest, weight);
break;
case 2:
printf("请输入源节点和目标节点的编号:");
scanf("%d %d", &src, &dest);
removeEdge(graph, src, dest);
break;
case 3:
printf("请输入源节点和目标节点的编号:");
scanf("%d %d", &src, &dest);
printf("边是否存在:%s\n", isEdge(graph, src, dest) ? "是" : "否");
break;
case 4:
printf("感谢使用,再见!\n");
break;
default:
printf("输入错误,请重新输入!\n");
break;
}
} while (option != 4);
}
int main() {
interactivePage();
return 0;
}
```
这段代码实现了一个简单的图算法系统,包括添加边、删除边和判断边是否存在等基本操作,并使用交互式页面与用户进行交互。你可以根据自己的需求,修改和完善这个系统,实现更多的功能。
