在本节中,我们将看到如何比较三个给定值的中间值。因此,如果给出三个数字,如(10,30,20),则它将找到20,因为这是中间元素。首先让我们看一下算法,然后将其实现为C ++代码。
middle_of_three(a, b, c): Input: Three numbers a, b and c Output: The middle of these three Begin if a > b, then if b > c, then return b else if a > c, then return c else return a else if a > c, then return a else if b > c, then return c else return b End
#include <iostream> using namespace std; int mid_three(int a, int b, int c) { if (a > b) { if (b > c) return b; else if (a > c) return c; else return a; } else { if (a > c) return a; else if (b > c) return c; else return b; } } main() { int a = 10, b = 30, c = 20; cout << "Middle Out of Three "<< mid_three(a, b, c); }
输出结果
Middle Out of Three 20
