Struct over Class

Understanding when to use structs over classes in C++

This easy question tests foundational knowledge of C++ language design and the practical distinction between two closely related constructs. It appears in technical screens to verify that candidates understand not just syntax, but the reasoning behind idiom choices.

The question probes what separates structs from classes at the semantic level—why a programmer would reach for one over the other in real code. Strong answers reflect awareness of both technical defaults (access control, initialization behavior) and the cultural conventions that guide code clarity and intent. Interviewers use this to gauge whether you write intentional, readable C++.

• Access specifiers and visibility defaults
• Semantic signaling in aggregate types
• Initialization and construction patterns
