What will be the output of the following program?

#include<iostream.h>
#include<string.h> 
class CuriousTab
{
    char txtMsg[50]; 
    public:
    CuriousTab(char *str = NULL)
    {
    if(str != NULL)
       strcpy(txtMsg, str);
    }
    int CuriousTabFunction(char ch);
};
int CuriousTab::CuriousTabFunction(char ch)
{
    static int i = 0;
    if(txtMsg[i++] == ch)
        return strlen((txtMsg + i)) - i;
    else
        return CuriousTabFunction(ch);
}
int main()
{
    CuriousTab objCuriousTab("Welcome to CuriousTab.com!");
    cout<< objCuriousTab.CuriousTabFunction('t');
    return 0;
}

1. All function calls are resolved at compile-time in Procedure Oriented Programming.
2. All function calls are resolved at compile-time in OOPS.

#include<iostream.h> 
class CuriousTab
{
    int x, y; 
    public:
    CuriousTab(int xx = 10, int yy = 20 )
    {
        x = xx; 
        y = yy;
    }
    void Display()
    {
        cout<< x << " " << y << endl;
    } 
    ~CuriousTab()
    { } 
};
int main()
{
    CuriousTab objCuriousTab; 
    objCuriousTab.Display(); 
    return 0;
}

1. Once a reference variable has been defined to refer to a particular variable it can refer to any other variable.
2. A reference is not a constant pointer.
