Final answer:
The key features of function arguments are data type, name, and order.
Step-by-step explanation:
The key features of function arguments in programming are:
- Data Type: Function arguments have a specific data type which determines the kind of values that can be passed as arguments. For example, a function may have an integer argument, which means only integer values can be passed to the function.
- Name: Function arguments have names that are used to reference the values passed to the function. These names are used within the function to access the values and perform operations on them.
- Order: Function arguments have a specific order in which they need to be passed to the function. The order of the arguments determines which value corresponds to which argument within the function.
These key features are important in programming as they allow functions to receive inputs and process them accordingly, adding flexibility and reusability to the code.
