# Question 1: Declare three variables of type int, float, and str,
# then print their types using type().

a = 10
b = 10.5
c = "kalpan"

print(type(a))
print(type(b))
print(type(c))


# Question 2: Write a program that takes two numbers as input,
# converts them to integers, and prints their sum, difference,
# product, and quotient.

a = int(input("Enter first number: "))
b = int(input("Enter second number: "))

print("Sum:", a + b)
print("Difference:", a - b)
print("Product:", a * b)
print("Quotient:", a / b)


# Question 3: Predict the output of the following code, then verify by running it:
# x = "5"
# y = 3
# print(x * y)
#
# Prediction: "555" (string multiplied by int repeats the string)
# Actual Output:

x = "5"
y = 3
print(x * y)


# Question 4: Write a program that checks whether a number entered by the user
# is positive, storing the result of the comparison in a boolean variable.

a = int(input("Enter a number: "))

if a > 0:
    print("Number is positive")
    is_pos = True
else:
    print("Number is negative")
    is_pos = False


# Question 5: Explain the difference between implicit and explicit type conversion,
# with one example of each.
#
# Implicit Type Conversion:
#   Python automatically converts one type to another without user intervention.
#   Example: num_int = 10, num_float = 2.5, result = num_int + num_float
#   Here int is automatically converted to float, result = 12.5
#
# Explicit Type Conversion:
#   User manually converts one type to another using functions like int(), float(), str().
#   Example: num_str = "10", num_int = int(num_str)
#   Here we manually convert string to integer.
