What are the advantages and disadvantages of using async/await in asynchronous programming?

Advantages of async/await:

• Allows writing asynchronous code that looks like synchronous, simplifying reading and maintenance.
• Improves application performance by non-blocking execution of input/output operations.
• Simplifies error handling through try/catch.

Disadvantages:

• Can lead to debugging difficulties due to asynchronous call stack.
• Incorrect use of async/await may cause deadlocks or resource leaks.
• In some cases, the overhead of context switching can be noticeable.

Example of usage in C#:

public async Task<string> GetDataAsync()
{
    HttpClient client = new HttpClient();
    string result = await client.GetStringAsync("https://example.com");
    return result;
}

This code does not block the thread, waiting for a response, which increases application responsiveness.
