Which type of programming languages are designed to enforce strict type-checking and prevent memory-related vulnerabilities?

• A. Dynamic languages
• B. Type-safe programming languages
• C. Weakly typed languages
• D. Interpreted languages

Answer: (B)

Type-safe programming languages enforce strict type-checking so that values are used only in ways that are appropriate for their type. This means the language prevents operations that don’t make sense for a given value, such as treating a number as a memory address or calling a function with an argument of the wrong type. By catching these mismatches, the language reduces the risk of memory-related vulnerabilities that come from type confusion, invalid memory access, or improper memory management. This safety can be achieved either at compile time or at runtime, but the result is the same: many unsafe memory operations are disallowed or detected early. Many type-safe languages also incorporate memory safety features like bounds checking and automatic memory management, which further reduce vulnerabilities such as buffer overflows, dangling pointers, and accidental memory corruption. For example, languages with strong type systems and managed memory prevent a lot of raw memory misuse by design. In contrast, weaker typing allows more permissive type conversions, and merely being interpreted speaks to how the code runs rather than how strictly types are enforced. So, the description aligns best with type-safe programming languages.
