编写程序，由键盘上输入3个不相等的数，找出中间的那个数

#include <iostream>

int main()
{
int x,y,z;
cout<<"input three numbers:";
cin>>x>>y>>z;
cout<<"the mid one is:"<<y;
return 0;
}

#include <stdio.h>
main()
{int a,b,c;
printf("请输入3个整数");
scanf("%d,%d,%d",&a,&b,&c);
if(a<b){d=a;a=b;b=d;} //排序
if(a<c){d=a;a=c;c=d;}
if(b<c){d=b;b=c;c=d;}
printf("第二大的数是:%d",b);

}
