Zig for C++ programmers

[kassane]

Based on the requested proposal: #46

I would like to ask, either as an extra chapter or as an extension of the initial proposal, an explanation about the differences and equivalence for modern c++ programmers, emphasizing:

• Zero Cost Abstraction
• Allocators & pointers
• Strings handling
• Conteiners: Map, Tuple, List, ...
• Generic Programming
• Anonymous functions and functors
• Error handling (exception x error code)
• Object Oriented Programming
• Namespaces
• Compile time (constexpr x comptime)
• User Type and Type Conversion

Id like to see some examples of interacting with C++ structs/classes from zig code.

Today added support for these little language-specific show/hide tips. This one isn't very useful but my C++ is rusty. What do you think of this approach?

What do you think of this approach?

It's good for an initial reference. Particularly quoting C++'s most used feature std::vector<T>. This way you could also compare std::array<T> with C static array and zig array (different from zig slice).

I know not everything described above is applicable for this comparison since it involves too many internal compiler differences to explain. For example, C++ also has the complexity around const, constexpr, consteval and constinit.

When compared to zig comptime is closer to consteval (C++20) strictly compile-time. Since constexpr cannot guarantee compilation time, allows for both compile-time and runtime evaluation.
