It repeatedly collects information from the user about different dogs and prints a formatted bill for each. The billing process continues until the user signals the end by entering a sentinel value \u2014 <code>0<\/code> \u2014 for the dog owner&#8217;s ID number.<\/p>\n\n\n\n<p>To manage this, a <strong>while loop<\/strong> is used. The loop begins by asking the user to input the dog&#8217;s owner&#8217;s ID. If the ID is <code>0<\/code>, the loop immediately breaks, and the program exits gracefully. This approach ensures that customer data is processed continuously without restarting the program each time.<\/p>\n\n\n\n<p>Inside the loop, the program collects data on the dog&#8217;s name, breed, age, and weight. These inputs are stored in variables and then displayed in a neatly formatted bill. The <strong>weekly daycare fee is fixed at $75.00<\/strong>, so this value is declared as a constant (<code>WEEKLY_FEE<\/code>) at the beginning.<\/p>\n\n\n\n<p>Each bill includes all relevant data and presents it clearly for the customer. Formatting such as <code>f\"${WEEKLY_FEE:.2f}\"<\/code> ensures that currency is displayed to two decimal places.<\/p>\n\n\n\n<p>This structure is scalable, efficient, and user-friendly. By using a <strong>sentinel-controlled loop<\/strong>, the program avoids hardcoding a number of customers and remains flexible to varying input amounts \u2014 a best practice in real-world applications.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">\ud83d\udd04 Flowchart Structure<\/h3>\n\n\n\n<pre class=\"wp-block-preformatted\">plaintextCopyEdit<code>      [Start]<br>         |<br>         v<br>[Input Owner ID Number]<br>         |<br>         v<br>[Is Owner ID == 0?]--Yes-->[End]<br>         | No<br>         v<br>  [Input Dog Name]<br>         |<br>  [Input Dog Breed]<br>         |<br>  [Input Dog Age]<br>         |<br>[Input Dog Weight]<br>         |<br>[Display Bill]<br>         |<br>         v<\/code><br><br><br><br><br><br><br><br><br><\/pre>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-483.jpeg\" alt=\"\" class=\"wp-image-234166\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Update our Doggy Daycare logic: pseudocode and Flowchart, to now continue to process customer bills until a sentinel loop control variable (pgs. 21, 171) is entered for: input ID number of the dog&#8217;s owner = 0.
