       a single statement after an IF must be surrounded with curly braces.
       You must always match an IF with an ELSE.

Explanation / Answer

Question5:Answer

Compare Operator

1. Add-- (+)
2.Multiply --(*)
3.Average--(it computes average of numbers).
4.compare (> and <) it compare two or more values return value as TRUE or FALSE.

Question 6: Answer

IF statements always contain a Boolean expression. (TRUE , it returns boolea values like TRUE or FALSE)

a single statement after an IF must be surrounded with curly braces. (false braces are optional for single statements)
You must always match an IF with an ELSE. ( false no need to match if and else statements)
IF/ELSE structures cannot be nested. (false . it can be nested).

Question 7:Answer

int x = 2, y = 3;
if (x > y);
       Console.WriteLine(“x is greater than y”);

will,syntax

Reason :after if condition have semicolumn.

if (x>y)

error: if(x>y);

Question 8 : Answer

Below all False statements. 6>6 (it returns false)
5>=0 (it returns false) 5<=12(it returns false) 7!=8 (it returns false)

(c – 2) > b   ==> (8-2)>6==> 6>6
a >= 0         ===> 5>=0
a <= (b * 2)===> 5<=(6*2) ===> 5<=12
(2 + a) != c ===> (2+5)!=8 ==> 7!=8

Question 9 : Answer

            int x = 3, y = 5;
            if (x > y)
            {
                Console.Write("A, ");
                if (x + 1 > y)
                    Console.Write("B, ");
                else
                    Console.Write("C, ");
            }
            else
                Console.Write("D, ");

Output is D,

3>5 it returns false value it no need to go if statements.
directly go to else statement.

where as catch block to allow exceptions it continue witout even resetting the trace.
