Learning notes-template functions and templates

# Include <iostream>
Using namespace STD;
Template <typename type>
Type max (Type X, Type Y)
{
If (x> Y)
{
Return X;
}
Else
{
Return y;
}
}

Template <typename parameter1 = int, typename parameter2 = int>
Class
{
Parameter1 X;
Parameter2 y;
Public:
Void setdata (parameter1 X, parameter2 y)
{
This-> X = X;
This-> Y = y;
}
Void display () const
{
Cout <"x =" <x <Endl;
Cout <"Y =" <Y <Endl;
}
};
Int main ()
{
A <int, float> A;/* can be like this a <> A; this indicates that the default parameter type parameter1 = int, parameter2 = int can be called, but not a; in this way, an error is reported during compilation,
The order must be consistent with that defined by the template. Otherwise, an error occurs */
A. setdata (11, 12.363 );
A. Display ();
Int max = max <int> (); // You can also write int max = max (). In this way, typename is defined according to the parameter type in the brackets, however, the two parameter types must be consistent.
Int N;
Cin> N;
Return 0;
