//求最大公约数
#include<iostream>
#include<cstdlib>
using namespace std;

int main()
{
int x,y;
cout<<"Please input two numbers:";
cin>>x>>y;
cout<<gcd(x,y);
return 0;
}
int gcd(int x,int y)

x%=y;
{while(x)gcd(y,x)}

}
#include<iostream>
#include<cstdlib>
using namespace std;
int gcd(int x,int y);
int main()
{
int x,y;
cout<<"Please input two numbers:";
cin>>x>>y;
cout<<gcd(x,y);
return 0;
}
int gcd(int x,int y)
{
x%=y;
{while(x)gcd(y,x)}

}
#include<iostream>
#include<cstdlib>
using namespace std;
int gcd(int x,int y);

cout<<gcd(x,y);
return 0;
}
int gcd(int x,int y)
{
if(x%y==0)
return y;
else
return gcd(y,x%y);
}
// 把第二个函数改成:
int gcd(int x,int y)
{
int z;
if(x<y){z=x; x=y; y=z;}
while(z=x%y){
x=y;
y=z;
}
return abs(y);
}
