The cost depends on the <strong>area code<\/strong> and <strong>duration<\/strong> of the call. If the <strong>called area code is different from the customer&#8217;s area code<\/strong> <em>and<\/em> the call <strong>lasts more than 20 minutes<\/strong>, a reduced rate of <strong>2 cents per minute<\/strong> applies. This likely encourages customers to make longer calls outside their local area. All other scenarios\u2014including shorter long-distance calls or calls within the same area code\u2014are billed at a standard <strong>13 cents per minute<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The logic behind this billing model is to give customers a discount for engaging in longer long-distance communications, possibly as a marketing tactic. The flowchart helps visualize the program\u2019s decision-making steps: we first determine if the call is a long-distance one by comparing the area codes. If it&#8217;s long-distance, we check if the call duration exceeds 20 minutes. This leads us to set the proper rate and finally compute the charge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This kind of flowchart is useful in <strong>telecommunication software<\/strong>, <strong>billing systems<\/strong>, and <strong>customer support tools<\/strong>, ensuring that customers are charged correctly. Displaying all relevant information\u2014like phone numbers, area codes, call duration, and charge\u2014ensures <strong>transparency and accuracy<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A proper implementation of this logic ensures that all customers are billed fairly based on clearly defined criteria, and it streamlines the process of developing or debugging billing software.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">\ud83d\udccc Flowchart Diagram (Text Representation)<\/h3>\n\n\n\n<pre class=\"wp-block-code\"><code>&#91;Start]\n   \u2193\n&#91;Input: Cust.
