Question

编写一个算法,从小到大依次输出顺序读入的三个整数x,y,z的值.

Answer 1

c++:
#include <iostream.h>
int max(int a,int b)
{ return a>b?a:b;}
int min(int a,int b)
{ return a<b?a:b;}
int max(int a,int b,int c)
{
return max(a,max(b,c));
}
int min(int a,int b,int c)
{
return min(a,min(b,c));
}
void main()
{ int x,y,z,a,b,c;
cout<<"请输入3个整数:"<<endl;
cin>>x>>y>>z;
a=max(x,y,z);
b=min(max(x,y),max(x,z),max(y,z));
c=min(x,y,z);
cout<<"从小到大依次为"<<c<<" "<<b<<" "<<a<<endl;
}

Answer 2

void
Rank()

{
printf("Input three number:\n");

int x,y,z,temp;

scanf("%d%d%d",&x,&y,&z);

if(x>y)

{
temp=x;
x=y;
y=temp;
}

if(x>z)

{
temp=x;
x=z;
z=temp;
}

if(y>z)

{
temp=y;
y=z;
z=temp;
}
printf("The Rank From Small To Big:%d %d %d",x,y,z);
}

解析：经过交换数值后，x,y,z依次保存从小到大的值
