What are the differences between LINQ and lambda expressions?

LINQ, which stands for Language Integrated Query, is a querying language used for querying and operating on data sources. Lambda expressions, on the other hand, are a syntax used for creating anonymous functions or delegates. The main difference between them lies in:

1. LINQ is a comprehensive query language that provides a set of methods and syntax for querying and manipulating data, while Lambda expressions are only used for creating anonymous functions or delegates.
2. LINQ can be used with a variety of data sources, such as databases, collections, and XML. Lambda expressions are commonly used to pass conditions or operations in LINQ queries.
3. LINQ offers a more intuitive and understandable syntax, making it easier for developers to write and maintain querying code. On the other hand, Lambda expressions are more concise and flexible, suitable for specific scenarios and requirements.

In general, LINQ is a more advanced query language, while Lambda expressions are a more flexible and concise syntax. They can be used together to conveniently query and manipulate data.
