Description: Write code that does the following: • Uses a lambda expression that accepts two int arguments, a and b, and returns the value of a * b. • Assigns the lambda expression to a variable named multiply. • Uses the multiply variable to call the lambda expression, passing the values 2 and 10 as arguments. The result should be assigned to an int variable named product.

Key Concepts

Lambda Expression

A lambda expression is a concise way to represent an anonymous function. It allows you to write small function implementations inline without formally declaring a named function, making the code more succinct and readable, especially for simple operations.

Anonymous Function

An anonymous function is a function defined without a name. Lambda expressions are a form of anonymous functions because they can be defined on the fly and assigned directly to variables, enabling flexible and concise code writing.

Function Assignment and Invocation

In programming languages that support first-class functions, functions (including lambda expressions) can be assigned to variables. This means you can store a function in a variable and then call it later using that variable, just like calling any regular function.

Parameter Passing

Parameter passing is the process of supplying inputs to a function. When using lambda expressions, you can specify parameters (in this case, two integers) that the function will use when executed, allowing for dynamic computation based on the provided arguments.
