What must be true about the programming language that the following line of code comes from?

Question

string greeting = "Hello, world!";


It is declarative
It is declarative

It is imperative

Answer 1

The line of code string greeting = "Hello, world!"; suggests that the programming language has the following characteristics:

1. Strong Typing: The use of string indicates that the language has a type system where variable types are specified. This suggests the language is likely statically typed.

2. Variable Declaration: The syntax indicates the language allows for the declaration and initialization of variables.

3. Assignment Operator: The use of the = sign indicates that the language uses an assignment operator to assign values to variables.

Based on these characteristics, the language is likely not purely declarative, but more imperative. Imperative languages emphasize how to perform tasks through statements that change a program's state, which aligns with the assignment and variable declaration in the code snippet.

So, the correct conclusion is that the language is imperative.
