Consider the following code segment.

int x;
x = 53;
if (x > 10){
    Console.Write(“A”) ;
}
if (x > 30){
    Console.Write(“B”) ;
}
else if (x > 40){
    Console.Write(“C”) ;
}
if (x > 50){
    Console.Write (“D”) ;
}
if (x > 70){
    Console.Write (“E”) ;
}

What is output when the code is executed?

1. A
2. D
3. ABD
4. ABCD
5. ABCDE

In the following code segment, you may assume that a, b, and n are all type int.

if (a != b && n / (a - b) > 90){
	/* statement 1 */
}else{
	/* statement 2 */
}
/* statement 3 */

What will happen if a == b is false?

1. /* statement 1 */ will be executed.
2. /* statement 2 */ will be executed.
3. Either /* statement 1 */ or /* statement 2 */ will be executed.
4. A compile-time error will occur.
5. An exception will be thrown.

Consider the following code segment. Assume num is a properly declared and initialized int variable.

if (num > 0){
    if (num % 2 == 0){
        Console.WriteLine("A");
    }else{
        Console.WriteLine("B");
    }
}

Which of the following best describes the result of executing the code segment?

1. When num is a negative odd integer, "B" is printed; otherwise, "A" is printed.
2. When num is a negative even integer, "B" is printed; otherwise, nothing is printed.
3. When num is a positive even integer, "A" is printed; otherwise, "B" is printed.
4. When num is a positive even integer, "A" is printed; when num is a positive odd integer, "B" is printed; otherwise, nothing is printed.
5. When num is a positive odd integer, "A" is printed; when num is a positive even integer, "B" is printed; otherwise, nothing is printed.
