Which kind of language should a programmer use if they want a compiler to report an error when an integer variable is assigned a string?

A programmer should choose a statically typed language if they want the compiler to enforce type safety by reporting an error when an integer variable is assigned a string. In statically typed languages, the type of a variable is known at compile time. This means that any type mismatches, such as attempting to assign a string value to an integer variable, will be caught by the compiler before the program is even run. As a result, this provides an additional layer of safety and prevents runtime errors related to type violations.

In contrast, dynamically typed languages do not require variable types to be declared at compile time. Variable types are determined at runtime, which means that assigning a string to an integer variable can occur without immediate detection, potentially leading to runtime errors. Object-oriented and markup languages do not directly address variable type enforcement in the same way; object-oriented languages can be statically typed or dynamically typed, and markup languages focus on the organization and structure of data rather than on variable types. Therefore, for ensuring type correctness at compile time, a statically typed language is the most appropriate choice.
