升序C ++

Question

我遇到了一个函数定义，该函数定义用于按升序和从何处开始对数字进行排序。它只有三个数字，所以我最好做if语句或数组吗？

#include<iostream>
#include<array>  //if I wish to use an array

using namespace std;

//Function defintion for sortie goes here 
void sortie(int first, int second, int third)

int main()
{
    cout << "Enter three numbers ";
    int first, second, third;
    cin >> first >> second >> third;
    cout << endl;
    cout << "Unsorted: " << first << ", " << second << ", " << third << endl;
    sortie(first, second, third);  //the function is being called here 
    cout << "Sorted:   " << first << ", " << second << ", " << third << endl;
    return 0;
}

Answer 1

您需要更改参数，因此原型将为：

void sortie(int& first, int& second, int& third);

然后只用一些swap来订购它们。
