程序代码:
#include<iostream> using namespace std; int main() { void swap(int x,int y,int z); int x,y,z; cout<<"Please enter three number:"; cin>>x>>y>>z; swap(x,y,z); return 0; } void swap (int &a,int &b,int &c) { int d; if (a>b){d=a;a=b;b=d;} if(c>b)cout<<a<<" "<<b<<" "<<c<<endl; else if(c<a)cout<<a<<" "<<a<<" "<<b<<endl; else cout<<a<<" "<<c<<" "<<b<<endl; }运行结果
