C# Switch Case with 💻Lamda Expression

In C#, the switch statement is used for conditional branching based on the value of an expression. It allows you to compare the expression against multiple possible constant values (cases) and execute the code block associated with the first matching case. The switch statement provides a more concise way to handle multiple conditional branches compared to using a series of if-else if statements.
