C++练习题1："输入三个数，输出最大值"

// stdycpp01.cpp : 此文件包含 "main" 函数。程序执行将在此处开始并结束。
//"输入三个数，输出最大值"
//两种方法：1.输入值，然后进行比较，然后输出
// 2.装入容器数组，利用api直接输出

 

 1 #include <iostream>
 2 #include <vector>
 3 #include <algorithm>
 4 
 5 using namespace std;
 6 
 7 int main()
 8 {
 9 int a, b, c, m;
10 cout << "输入三个数，输出最大值" << endl;
11 cin >> a >> b >> c;
12 int a1[] = { a, b, c };
13 int max_a1 = *max_element(a1, a1 + 3);
14 int max_a1_xb= max_element(a1, a1 + 3)-a1;
15 int* max_a1_xb_pt = &max_a1_xb;
16 vector<int>num = { a,b,c };
17 int max_num = *max_element(num.begin(), num.end());
18 int max_num_xb= max_element(num.begin(), num.end())-num.begin();
19 cout << "最大值是：" << endl;
20 m = a;
21 if (b > m)
22 m = b;
23 if (c > m)
24 m = c;
25 cout << m << endl;
26 cout << "容器获取最大值:" << max_num << endl;
27 cout << "容器获取最大值下标:" << max_num_xb << endl;
28 cout << "数组获取最大值：" << max_a1 << endl;
29 cout << "数组获取最大值下标：" << max_num_xb << endl;
30 cout << "数组获取最大值下标指针：" << *max_a1_xb_pt << endl;
31 // std::cout << "Hello World!\n";
32 }
