What will be the output of the following program?

#include<iostream.h> 
typedef void(*FunPtr)(int);
int Look(int = 10, int = 20);
void Note(int); 
int main()
{
    FunPtr ptr = Note;
    (*ptr)(30); 
    return 0;
}
int Look(int x, int y)
{
    return(x + y % 20);
}
void Note(int x)
{
    cout<< Look(x) << endl;
}
