C++ is implemented with a function with default parameters to find the largest number among 2 or 3 positive integers

1. The subject requirements are as follows:

C++ is implemented with a function with default parameters to find the largest number among 2 or 3 positive integers

2. Come on, show:

#include <iostream>
using namespace std;

void sort(int a,int b)
{
    int temp;
    if (a>b){temp = a;a = b;b = temp;}
    cout <<a<< ',' <<b<<endl;
}

void sort(float x,float y,float z)
{
    float temp;
    if(x>y){temp=x;x=y;y=temp;}
    if(z<x) cout <<z<< ',' <<x<< ',' <<y<< endl;
        else if(z<y) cout <<x<< ',' <<z<< ',' <<y<< endl;
            else cout <<x<< ',' <<y<< ',' <<z<< endl;
}

int main()
{
    void sort(int a,int b);
    void sort(float x,float y,float z);
    float x,y,z;
    int a,b;
    cout <<"请输入两个整数："<<endl;
    cin >>a>>b;
    cout << "排序从小到大为：" << endl;
    sort(a,b);
    cout <<"请输入三个浮点数："<<endl;
    cin >>x>>y>>z;
    cout << "排序从小到大为：" << endl;
    sort(x,y,z);
    return 0;
}

3. The running results are as follows:
