template question

[li0524158198]

Write your question here.

template <class T>
T Max(T a, T b)
{
  cout <<"template:";
  return a < b ? b: a;
}

#include<iostream.h>
int Max(int x, int y)
{
  cout <<"Loading function0:";
  return (x > y) ? x : y;
}

int Max(char x,int y)
{
  cout<<"Loading function1:";
  return (x > y) ? x : y;
}

int Max(int x, char y)
{
  cout<<"Loading function2:";
  return (x > y) ? x : y;
}

void main()
{
  int i= 10;
  char c='a';
  double d=2.14;
  cout<<Max(d,i)<<endl;
  cout<<Max(i,d)<<endl;
}

result:

Loading function1:10
Loading function2:10
Press any key to continue

why not call "int Max(int x, int y)" ?

It looks like you are using an old compiler. It should give an error.

 error: call of overloaded ‘Max(double&, int&)’ is ambiguous
 note: candidates are: int Max(int, int)
 note:                 int Max(char, int)
 note:                 int Max(int, char)
