Question 1: Write A Program That Asks The User For A Positiv

Question 1write A Program That Asks The User For A Positive Nonzero I

Assignment Instructions:

Write a program that asks the user for a positive nonzero integer value. The program should use a loop (while loop) to get the sum of all the integers from 1 up to the number entered. Use a separate loop to validate the user input, ensuring the number is positive and nonzero. Another loop should compute the sum of integers from 1 to that number.

Paper For Above instruction

This program begins by prompting the user to input a positive, nonzero integer. To ensure data validity, a validation loop repeatedly asks for input until the user enters a number greater than zero. This loop prevents invalid inputs such as zero or negative numbers, safeguarding the program's correctness and robustness. Once a valid number is obtained, the program initiates a second loop to compute the sum of all integers from 1 to the entered number. This is achieved by initializing a sum variable to zero and iteratively adding each integer in the range to this total. The process employs a while loop that continues until the current number exceeds the user-entered value. Finally, the program displays the computed sum, providing a clear output related to the initial input.

The use of two while loops — one for input validation and another for summing the sequence — demonstrates an understanding of control flow in programming. Input validation ensures the program operates with meaningful data, thus avoiding logical errors or exceptions. The summing loop provides an example of accumulating totals efficiently using iteration. Incorporating user prompts, validation, and looping constructs underlines the importance of defensive programming and user interaction considerations in software development.
