Which term describes programming languages that enforce strict type-checking at compile time to prevent certain classes of memory errors?

• A. Type-safe programming languages
• B. XSS
• C. Vulnerability scanner
• D. Credentialed scan

Answer: (A)

Type safety and compile-time type checking describe how a language enforces that operations use data of the correct type, preventing memory-related mistakes. When a language performs strict type-checking during compilation, the compiler rejects code where values are used in ways that don’t match their types. This catches many memory-safety issues before the program runs, such as applying arithmetic to non-numeric data, dereferencing invalid or misinterpreted pointers, or writing beyond the bounds of a memory region. By enforcing these rules, memory corruption becomes much less likely because operations that could lead to such errors are disallowed at compile time. Languages designed with strong type systems and static type checking aim to reduce memory safety risks, with examples like Rust and Java illustrating how type discipline and managed memory help prevent classes of memory errors. Other choices—XSS, vulnerability scanners, and credentialed scans—pertain to web security or security assessment tools rather than how a programming language enforces memory safety.
