Validating Phone Number List Formats
Posted: Thu May 22, 2025 6:52 am
Once upon a time in a small town called Techville, there lived a young girl named Mia. Mia loved technology, and she dreamed of becoming a computer programmer one day. One sunny morning, her teacher announced an exciting project: each student needed to create a program that could validate phone number formats.
Mia felt a mix of curiosity and excitement. She had seen people type phone numbers in different ways. Some people would use dashes, others would use spaces, and some wrote only the numbers. Mia wondered how she could make a program to check all these variations.
After school, Mia rushed home, sat at her computer, and began to write her program. She knew that in her town, people used different formats. For instance, some wrote their phone numbers like this: 123-456-7890, mexico phone number list while others simply wrote it as 1234567890. There were also those who used spaces: 123 456 7890. Mia wanted her program to accept all these formats.
She started by looking up information about phone number formats online. Mia learned that in the United States, a standard phone number has ten digits. The first three digits are called the area code, and the next seven are the local number. She realized that her program needed to check for this basic information.
Mia began writing her code. She used logical statements to check if the phone number contained 10 digits. But then she faced a problem. What if someone made a mistake and added letters or symbols? Mia brainstormed and decided to use a special tool called a regular expression. It would help her find only the numbers.
After several hours of testing and fixing bugs, Mia finally finished her program. She felt a rush of joy. To make sure it worked, she typed in many phone numbers with different formats. It accepted all the correct ones and rejected those with mistakes. Mia was proud of her work, but she wanted to make it even better.
The night before the presentation at school, Mia added a feature that could suggest a correct format if someone typed a wrong number. The next day, she stood in front of her classmates and demonstrated her program. Everyone was impressed!
Her teacher praised her for creativity and hard work. Mia learned that with curiosity and determination, she could solve any problem that came her way. From that day on, Mia knew she was on her path to becoming a great programmer.
