Predict the Output (Java)

int x = 10, y = 20;

System.out.println((x > y) ? x : y);

• 20

• 10

• 30

• Will Generate error

Predict the Output (Python)

x = 10

def foo()

<tab> x = 20

<tab> print(x)

foo()

print(x)

• 20, 10

• 20, 20

• 10, 10

• 10, 20

Predict Output (C)

#include <stdio.h>

int main() {

int i = 5;

printf("%d", i++ * ++i);

return 0;

}

• 10

• 15

• 35

• 12

Guess the output (Java)

public class Test {

public static void main(String[] args) {

int x = 5;

if (x < 10 || (++x > 10)) {}

System.out.println(x);

}

}

• 5

• 10

• 15

• True

Complete the Code (Python) (ignore syntactical error, if noticed)

# Fill in the missing part to calculate the sum of even numbers up to n

def sum_even(n)

<tab> total = 0

<tab> for i in range(1, n+1):

<tab> <tab> if _________: # Fill here

<tab> <tab> <tab> total += i

<tab> return total

Debug the Code & Fix the error (C)

#include <stdio.h>

int main() {

int arr[5] = {1, 2, 3, 4, 5};

for (int i = 0; i <= 5; i++) {

printf("%d ", arr[i]);

}

return 0;

}

Predict the Output (Java) (ignore syntactical error, if noticed)

public class Test {

public static void main(String[] args) {

int x = 5;

System.out.println(x++ + ++x);

}

}

Function to Check Prime

def is_prime(n):

for i in range(2, _________): # Fill here

if n % i == 0:

return False

return True

Debug the Code & Fix the error (Java)

String a = "hello";

String b = "hello";

if (a == b) {

System.out.println("Match");

} else {

System.out.println("No Match");

}

Predict the Output (Java)

public class Test {

public static void main(String[] args) {

int x = 10;

int y = 3;

System.out.println(x / y);

}

}
