Question: 1 / 400

What are implicitly typed variables?

Variables with type explicitly declared

Variables where type is inferred by the compiler

Implicitly typed variables are those for which the type is inferred by the compiler at compile time, rather than being explicitly declared by the programmer. This feature is particularly useful in languages like C# where you can use the 'var' keyword to declare a variable without specifying its type. The compiler determines the variable's type based on the value assigned to it.

For instance, if you write `var number = 10;`, the compiler infers that `number` is an integer because the assigned value is an integer literal. This allows for more concise code while still maintaining type safety, as the type is all handled at compile time. The compiler uses the information available during the assignment to determine the variable's type, which enhances code readability and can reduce redundancy when the type is clear from the context.
