The myth that C programming language lacks encapsulation and isolation is debunked.Despite not having classes, in C, structs can provide encapsulation and isolation.Unlike in modern languages, in C, all fields in a struct are public and accessible.Modules in C are encapsulated via interface and implementation files.Header files serve as contracts for users of the module, hiding implementation details.C allows for creating objects with hidden fields and guarded access via functions.This approach in C provides encapsulation and isolation with strong guarantees.The implementation details of C structs can be hidden from callers, ensuring data integrity.Objects created in C can be used across different programming languages like Python, PHP, and Java.The article emphasizes the importance of understanding the capabilities of C programming language.
