1. Print Numbers Using Do-While Loop
Write a C program to print numbers from 1 to 10 and 10 to 1 using a do-while loop.
2. Sum of Positive Integers Until 0
Write a C program that prompts the user to input a series of integers until the user stops by entering 0 using a do-while loop. Calculate and print the sum of all positive integers entered.
3. Sum of Even and Odd Numbers
Write a C program that calculates the sum of even and odd numbers from 1 to 50 using do-while loops.
4. Sum Until Negative Number
Write a C program that prompts the user to enter a series of numbers until they input a negative number. Calculate and print the sum of all entered numbers using a do-while loop.
5. Random Number Guessing Game
Write a C program that generates a random number between 1 and 100 and asks the user to guess it. Use a do-while loop to give the user multiple chances until they guess the correct number.
6. Sum of Squares of Digits
Write a C program that prompts the user to enter a positive integer and then calculates and prints the sum of the squares of each digit in that number using a do-while loop
7. Average of User Input Numbers
Write a C program that calculates the average of a set of numbers input by the user. The user should be able to input as many numbers as desired, and the program should continue until the user decides to stop.
8. Password Validation
Write a C program that prompts the user to enter a password. Use a do-while loop to keep asking for the password until the correct one is entered.
9. Sum of Prime Numbers
Write a C program that calculates and prints the sum of prime numbers up to a specified limit (e.g., 50) using a do-while loop.
10. Count Digits in a Number
Write a C program that implements a program to count the number of digits in a given integer using a do-while loop.
11. Compound Interest Calculation
Write a C program that calculates the compound interest for a given principal amount, interest rate, and time period. Use a do-while loop to allow the user to input values multiple times.
12. Reverse a Number
Write a C program to reverse a given number using a do-while loop.
