Conditionals and Loops

Question 1)

What does the following program print?

public static void main(String[] args)

{

int a = 25

int b 3;

int c 4;

if (a < b)

{

if (b < c)

{

if (c < a) System.out.println (a +" " + b+c);

else System . out . println (c +" " + b +""+ a);

}

else System.out.println(a + " " +C +" " + b);

}

else System . out.println (b +"* *" +c)

}

Question 2)

Which of the following will lead to a compile-time error? Mark all that apply.

if a > b, then c = 0;

if a > b {c = 0; }

if (a > b) c = 0 else b = 0;

if (a > b) c = 0;

if (a > b) (c = 0; )

if (a> b) then c = 0;

if (a > b) { c - 0;}

Question 3)

Which of the following errors will be detected at compile time? Mark all that apply.

Missing left curly brace
Missing semicolon at the end of a statement
Trying to subtract two strings
Missing curly braces around a sequence of statements in a while loop
Division by a variable that might be zero
Forgetting to declare the type of a variable

Question 4)

What is the value of m after executing the following code?

int n = 123456789;

int m = 0;

while (n != 0)

{

m = (10 * m) + (n % 10);

n = n / 10;

}
