The markdown data provides instructions for developers in different programming languages. A C# developer is tasked with writing code to identify and print duplicate records from a given CSV file. A JavaScript developer is asked to create a program that validates form information, specifically ensuring that name and email fields are filled, while address and age fields are optional. Lastly, a PHP developer is required to write a program that checks for the presence of a substring within a string.
In summary, these tasks are designed to test the skills of developers in different programming languages. They involve data manipulation, form validation, and string manipulation. Each task is specific to the capabilities and syntax of the respective programming language, demonstrating the unique applications and strengths of C#, JavaScript, and PHP.
Key takeaways:
As a C# developer, one can write code to read and print duplicate records from a CSV file.
JavaScript developers can write programs to validate form information, ensuring required fields like name and email are filled.
Optional fields in form validation, such as address and age, can be handled using JavaScript.
PhP developers can write programs to check if a string contains a specific substring.
