3. Write a program that reads an integer between 0 and 1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all its digits is 14. Hint: Use the % operator to extract digits, and use the / operator to remove the extracted digit. For instance, 932 % 10 = 2 and 932 / 10 = 93. A sample run: Enter a number between 0 and 1000: 999 The sum of the digits is 27

4. Randomly generate an integer number in range [10, 99]. Check if the digit at 10°s position is greater than the digit at 1's position. If yes, swap these 2 digits to generate a new number. Display original number and new number. For example, if the number is 43, after process, the new number will be 34. If original number is 12, no process needed. If the number is 50, the new number will be 5

24. Write a program which asks the user for an integer number and prints out whether the input number is a multiple of 7. A. Example 1 i. Input: • ii. Output: B. Example 2 i. Input: Please enter number: 9 ii. Output: Number is not a multiple of seven 25. Write a program which asks the user for two integer numbers (say N1 and N2) and prints out whether the input number NI is a multiple of N2. A. Example 1 i. Input: • B. Example 2 ii. Output: • i. Input: A. Example Please enter number: 49 Number is a multiple of seven i. Input: ii. Output: Number 40 is not a multiple of 3 26. Write a program which asks the user for an integer number and prints out whether the input number is even or odd. Please enter first number: 49 Please enter second number: 7 Number 49 is a multiple of 7 Please enter first number: 40 Please enter second number: 3 • Please enter number: 42 i. Input ii. Output: Number is even 27. Write a program that asks the user for an integer number and prints a pattern. A. Example…

Write a program that asks the user to enter 2 integers of 4 digits and displays thedifferent digits as X and * if they are the same. If the user enters a number which is notof four digits, then a convenient message is displayed.
