Question 1: Design a program in Python that takes two numbers as input and displays the sum and product of those numbers.
Answer:
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))
sum = num1 + num2
product = num1 * num2
print("The sum of the numbers is:", sum)
print("The product of the numbers is:", product)
Question 2: Write a Java program to find the factorial of a given number using a recursive function.
Answer:
public class Factorial {
public static int factorial(int n) {
if (n == 0 || n == 1) {
return 1;
} else {
return n * factorial(n - 1);
}
}
public static void main(String[] args) {
int number = 5;
int result = factorial(number);
System.out.println("The factorial of " + number + " is: " + result);
}
}
Question 3: Design an SQL query to retrieve the names of students who have scored above 80 marks in the “Mathematics” subject.
