In C++, there are two seemingly similar headers for input/output operations: iostream and iostream.h. However, they have key differences you should be aware of: 1. Standard vs. Non-Standard: **iostream** is the standard header for input/output operations in C++. It is part of the C++ Standard Library and is guaranteed to be available and consistent across different compilers. **iostream.h** is a non-standard header . It was used in pre-standard C++ and some early compilers. It is not part of the C++ Standard Library and its availability and behavior might vary depending on the compiler. 2. Namespace: **iostream** defines everything within the **std** namespace. This helps avoid naming conflicts with other libraries or user-defined functions. **iostream.h** does not use namespaces. This means all its elements are directly available in the global namespace, which can lead to potential naming conflicts and is generally considered less modern practice. 3. Recommendations: Always use iostr

We need os module to delete a file on hard drive import os if os.path.exists("myfile.txt"): os.remove("myfile.txt") print("Deleted successfully") else: print("No such file exists")

File handling in Python try: with open("myfile.txt", "r") as f1: with open("newfile.txt", "w") as f2: for i in f1: # print(type(f2)) f2.write(i) except: print("Sorry! The file does not exist. Plz create first.") else: print("Contents of file copied successfully.")

 The following program will find out the palindrome of numbers in a given list. If the number in the list is less than or equal to 10, it will be printed as such; if the number in the list is greater than 10, the next palindrome of that number will be calculated. But if the number greater than 10 is already a palindrome, then 1 will be added to it and then the next palindrome of that number will be found. mylist = [1, 6, 10, 11, 88, 535, 5439] plist = [] for number in mylist: if number <= 10: plist.append(number) elif number > 10: # comment out the following if block if palindrome in list to be written as such if str(number) == str(number)[::-1]: number += 1 while str(number) != str(number)[::-1]: number += 1 plist.append(number) print(plist)

 The following program takes user input as number(s) and tells whether the input is a palindrome. If it is not, it will return the next palindrome for that number. ncases = int(input("How many cases: ")) for i in range(ncases): case = input(f"Enter your case {i+1}: ") if case == case[::-1]: print("This is a palindrome") else: pali = case[:] while pali != pali[::-1]: pali = int(pali) + 1 pali = str(pali) if pali == pali[::-1]: print(f"The next palindrome for case {case} is {pali}")

 The following program takes a user input, be it a number or any word, and tells whether the input is a palindrome or not. ''' Whether a given word or number is a palindrome or not? ''' while True: word = input("Enter a word or number:\n") if word == word[::-1]: print(f"{word} is a palindrome") else: print(f"{word} is not a palindrome")

  # defining empty list uList = [] # defining the number of elements in the list nList = int(input("List of how many elements? ")) print("Now enter the elements of your list one by one.") # taking elements of the list as user input for i in range(0,nList): element = int(input()) uList.append(element) print(f"The original list is {uList}") # taking copy of the list, storing it in variable, then reversing it reverse1 = uList[:] reverse1.reverse() print(f"The first reverse of the original list {uList} is {reverse1}") reverse2 = uList[::-1] print(f"The second reverse of the original list {uList} is {reverse2}") reverse3 = uList[:] for i in range(len(reverse3)//2): reverse3[i], reverse3[len(reverse3)-i-1] = reverse3[len(reverse3)-i-1], reverse3[i] print(f"The third reverse of the original list {uList} is {reverse3}") if reverse1 == reverse2 and reverse2 == reverse3: print("All the three meth

 The following function in python will return the reverse of the given list. def reverseList(n): reverseL = uList[:] for i in range(len(reverseL)//2): reverseL[i], reverseL[len(reverseL)-i-1] = reverseL[len(reverseL)-i-1], reverseL[i] print(f"The reverse of the original list {uList} is {reverseL}") uList = [45,66,7,1,333] reverseList(uList)

The following Python program calculates 2 things; 1. when will the user turn 100 2. what will be the user's age in a certain year  # when will I be 100 years old age_yob = input("Plz enter your age or year of birth: ") # my age in the future year age_in_year = input("You age in a certain year: ") current_year = 2022 # age_in_year = float(age_in_year) # dealing age try: if len(age_yob) < 4: if len(age_yob) == 3: print("You are already 100 years old.") elif len(age_yob) < 3: age_100 = 100 - float(age_yob) print(f"You will turn 100 in {current_year + age_100}") add_to_age = float(age_in_year) - current_year age_asked = float(age_yob) + add_to_age print(f"You age in {age_in_year} will be {age_asked}") else: # dealing yob age_100 = float(age_yob) + 100 print(f"You will turn 100
