程序，用于在C ++中查找车轮图的直径，周期和边缘
例
#include <bits/stdc++.h>
using namespace std;
//计算周期数
int totalCycle(int vertices) {
int result = 0;
result = pow(vertices, 2) - (3 * vertices) + 3;
return result;
}
//计算边数
int Edges(int vertices) {
int result = 0;
result = 2 * (vertices - 1);
return result;
}
//计算直径
int Diameter(int vertices) {
int result = 0;
if (vertices == 4)
result = 1;
else
result = 2;
return result;
}
int main() {
int vertices = 4;
cout << "Number of Cycle = " << totalCycle(vertices) << endl;
cout << "Number of Edges = " << Edges(vertices) << endl;
cout << "Diameter = " << Diameter(vertices);
return 0;
}输出结果
Number of Cycle = 7 Number of Edges = 6 Diameter = 1
