Question

There are two distinct ways computer languages can approach variables?

1) Static typing
2) Dynamic typing
3) Strong typing
4) Weak typing

Answer 1

Static typing and dynamic typing are two distinct ways computer languages approach variable types. Static typing requires type declaration at compile-time, while dynamic typing determines types at runtime. Strong and weak typing relate to the strictness of typing rules.

Step-by-step explanation:

There are indeed two distinct ways computer languages can approach variables which closely relates to how they handle typing systems. These are known as static typing and dynamic typing.

Static typing is a property of a programming language where variable types are known at compile-time. This means that you must declare the type of a variable when you write your code and that type cannot change. Examples of statically typed languages include Java, C, and C++.

Dynamic typing, on the other hand, determines variable types at runtime. This means that you don't need to explicitly declare a variable type, and it can change as the program runs. Languages like Python, JavaScript, and Ruby use dynamic typing.

Both strong typing and weak typing are additional aspects of typing systems. Strong typing is where the rules about mixing variables of different types are strict, while weak typing allows more flexibility in using variables of different types together. These concepts are orthogonal to static and dynamic typing.
