c++ object constructor question

I have the following code

Code:
class Param{
    public:
    Param(int aa, int bb){
        a=aa;
        b=bb;
    }
int a,b;
};

void function(Param);

Code:
int main(){

   function(2,3);
    return 0;
}

Code:
void function(Param par){
    cout<<par.a;
}

, and when I run it, I get the following message error:

Code:
.../main.cpp|21|error: conversion from ‘int’ to non-scalar type ‘Param’ requested|

I know the problem is that function should have been called with an object from Param, but I was expecting that the constructor Param(int , int) would do the job.
What is wrong with my assumption, and how could I fix this problem?

thank you in advance!!

NAME
Lire::Param - Object which represents a parameter in a XML specification. DESCRIPTION
Lire::Param are objects which represent parameters in an XML specification. The object is used to represent the parameter's specification as well as its current value. new( 'name' => $name, 'type' => $type, [ 'default' => $default ] ) Creates a new Lire::Param object. name() Returns the name of this parameter. type() Returns this parameter's type. value( [ $new_value ] ) Returns (and optionnally modifies) the current value for this parameter. If no value was set, but a default is available, the default value will be returned. default( [ $new_default ] ) Returns (and optionnally changes) the parameter's default value. description( [ $new_description ] ) Returns (and optionnally changes) the current parameter's description. as_type_spec() Returns a Lire::Config::TypeSpec object which adequately represents the current parameter.
