Name the type of error ( syntax, runtime or logical error) in each case given below:

1. Math.sqrt (36 – 45)
2. int a;b;c;

If int x[] = { 4, 3, 7, 8, 9, 10}; what are the values of p and q ?

1. p = x.length
2. q = x[2] + x[5] * x[1]

What are the types of casting shown by the following examples:

1. char c = (char) 120;
2. int x = ‘t’;

Write a function prototype of the following:
A function PosChar which takes a string argument and a character argument and returns an integer value.

if (x%2 == 0)
System.out.print("EVEN");
else
System.out.print("ODD");

Give the output of the following string functions:

1. "MISSISSIPPI".indexOf('S') + "MISSISSIPPI".lastIndexOf('I')
2. "CABLE".compareTo("CADET")

Give the output of the following Math functions:

1. Math.ceil(4.2)
2. Math.abs(-4)

int m = 5, n = 10;
while (n>=1)
{
    System.out.println(m*n);
    n--;
}

Analyze the given program segment and answer the following questions:

1. Write the output of the program segment.
2. How many times does the body of the loop gets executed ?

for(int m = 5; m <= 20; m += 5)
{    if(m % 3 == 0)
        break;
    else
        if(m % 5 == 0)
            System.out.println(m);
    continue;
}

Give the output of the following expression:

a+= a++ + ++a + --a + a-- ; when a = 7

Write the return type of the following library functions:

1. isLetterOrDigit(char)
2. replace(char, char)

Using the switch statement, write a menu driven program for the following:

(i) To print the Floyd’s triangle [Given below]

1
2   3
4   5   6
7   8   9  10
11 12 13 14 15

(b) To display the following pattern:
I
I C
I C S
I C S E

For an incorrect option, an appropriate error message should be displayed.

Special words are those words which start and end with the same letter.
Example: EXISTENCE, COMIC, WINDOW
Palindrome words are those words which read the same from left to right and vice-versa.
Example: MALYALAM, MADAM, LEVEL, ROTATOR, CIVIC
All palindromes are special words but all special words are not palindromes.

Write a program to accept a word. Check and display whether the word is a palindrome or only a special word or none of them.

Design a class to overload a function sumSeries() as follows:

Write a program to accept a number and check and display whether it is a Niven number or not.
(Niven number is that number which is divisible by its sum of digits.).

Example:
Consider the number 126. Sum of its digits is 1 + 2 + 6 = 9 and 126 is divisible by 9.

Write a program to initialize the seven Wonders of the World along with their locations in two different arrays. Search for a name of the country input by the user. If found, display the name of the country along with its Wonder, otherwise display "Sorry not found!".

Seven Wonders:
CHICHEN ITZA, CHRIST THE REDEEMER, TAJ MAHAL, GREAT WALL OF CHINA, MACHU PICCHU, PETRA, COLOSSEUM

Locations:
MEXICO, BRAZIL, INDIA, CHINA, PERU, JORDAN, ITALY

Examples:
Country name: INDIA
Output: TAJ MAHAL

Country name: USA
Output: Sorry Not found!
