FYBCS C Exercise_5

Set A . Write C programs for the following problems. 

  1. Write a program to display all prime numbers between ____ and ____.

 2. Write a program to display multiplication tables from ___ to ___ having n multiples each. The output should be displayed in a tabular format. For example, the multiplication tables of 2 to 9 having 10 multiples each is shown below.  
2 × 1 = 2     3 × 1 = 3 ………….9 × 1 = 9  
2 × 2 = 4     3 × 2 = 6…………..9 × 2 = 18
 …………. …………. ................................. 
2 × 10 = 20 3 × 10 = 30………..9 × 10 = 90  

 3. Modify the sample program 1 to display n lines as follows (here n=4).             
 A      B      C      D              
E      F      G              
H      I              
J 

Set B. Write C programs for the following problems. 

  1. Write a program to display all Armstrong numbers between 1 and 500. (An Armstrong number is a number such that the sum of cube of digits = number itself Ex. 153 = 1*1*1 + 5*5*5+ 3*3*3 

 2. Accept n numbers and display the number having the maximum sum of digits

 3.Display all perfect numbers below 500[A perfect number is a number, such that the sum of its factors is equal to the number itself]. Example: 6 (1 + 2 + 3), 28 (1+2+4+7+14)

    class BankAccount:
    def __init__(self, owner, balance=0):
    self.owner = owner
    self.balance = balance

    def deposit(self, amount):
    self.balance = self.balance + amount
    print("Deposited",amount , "New balance:", self.balance)

    def withdraw(self, amount):
    self.balance = self.balance - amount
    print("Withdrew", amount, "New balance: ",self.balance)

    def check_balance(self):
    print("Current balance: ", self.balance)
    return self.balance

    account = BankAccount("Alice", 100)
    account.check_balance()
    account.deposit(50)
    account.withdraw(30)
    account.withdraw(200)
    account.check_balance()

    while(True):
    try:
    numerator = float(input("Enter the numerator: "))
    denominator = float(input("Enter the denominator: "))
    result = numerator / denominator

    except ValueError:

    except ZeroDivisionError:
    print("Error: Division by zero is not allowed.")

    else:
    print(f"The result of division is: {result:.2f}")

    finally:
    print("Program execution completed. \n")
