use of constructor problem

[archive]

Error:shi::shi(int)' and `shi::shi(int)' cannot be overloaded, dont exactly know what that means....help please!

  #include <iostream>
using namespace std;

class shi{
public:
int age;
shi(int x)

{
age = x;
};
shi (int y)
{
age = y;
};

friend int add(shi so,shi sw);


};
int add(shi so,shi sw)

{
return so.age + sw.age;
};

int main()
{int c;
shi s1(46);
shi s2(51);
c = add(s1.age,s2.age);

cout<<c;
}

this constructor

shi(int x)

{
age = x;
};

and this constructor are the same

shi (int y)
{
age = y;
};

you can only have one
