       Show the steps.

(c) What is the purpose of default in a switch? 

(d) Give the difference between linear search and binary search.

(e) What will be the output of the following code?

Question 3

(a) State the difference between if-else if ladder and switch...case. 

(b) Explain the concept of constructor overloading with an example. 

(c) What will be the output of the following program segments?

(i) String s = “application”;

    int p = s.indexOf(„a‟);

    System.out.println(p);

    System.out.println(p+s);

(ii) String st = “PROGRAM”;

    System.out.println(st.indexOf(st.charAt(4))); 

(iii) int a = 0;

     if(a>0 && a<20)

     a++;

     else a-- ;

     System.out.println(a); 

(iv) int a= 5, b = 2,c;

     if (a>b || a ! = b)

     c = ++a+--b;

     System.out.print(c+ “ ”+a+ “ ”+b); [2]

(v) int i = 1;

    while(i++<=1)

  {

    i++;

    System.out.print(i + “ ” );

}

    System.out.print(i); 

(d) Differentiate between isUpperCase(char) and toUpperCase(char). 

(e) What is the difference between a constructor function and a member function of a class?
