SUPPORTSDataStructure

std::string

SUPPORTSSolution

then you might use `std::visit` for the multi-dispatch. Tension: Not addable. Outcome: if constexpr (requires { t1 + t2; } ).

SUPPORTSRootCause

it turns out that "synthesized three-way comparison" is used to compare each individual class member in a `=default`ed `operator`. Outcome: the synthesized three-way comparison happens twice: first for `a = m.x, b = n.x`, then for `a = m.y, b = n.y`.

SUPPORTSSolution

it turns out that "synthesized three-way comparison" is used to compare each individual class member in a `=default`ed `operator`. Tension: And `T` is shared across all members. Outcome: the synthesized three-way comparison happens twice: first for `a = m.x, b = n.x`, then for `a = m.y, b = n.y`.

SUPPORTSSolution

Game developers prefer C++ for engines and performance-sensitive subsystems — for engines and performance-sensitive subsystems. Tension: maximal control over performance, memory layout, and platform integration while keeping runtime overhead minimal.

PERTAIN_TORootCause

class DerivedB: public B.

PERTAIN_TORootCause

std::put_time is a stream manipulator that writes formatted characters to an ostream, not a std::string

PERTAIN_TOSolution

Use std::ostringstream, stream std::put_time output into it, then call str() to get a std::string

PERTAIN_TORootCause

ofstream does not throw on open errors unless exception flags are enabled

PERTAIN_TORootCause

MSVC considers `A` to be a typedef name for linkage purposes — The type of `a` is not defined in a typedef declaration. Tension: it does not have a typedef name for linkage purposes. Outcome: The type of `a` is not defined in a typedef declaration.

PERTAIN_TOSolution

The type of `a` is not defined in a typedef declaration — An unnamed class or enumeration `C` defined in a typedef declaration. Tension: does not have a typedef name for linkage purposes. Outcome: has the first typedef-name declared by the declaration to be of type `C` as its typedef name for linkage purposes.

PERTAIN_TOSolution

then the variable should be copied (removing &). Tension: `msg.append(" World")` seems to modify `msg`. Outcome: the lambda must be mutable.

PERTAIN_TORootCause

construct_at takes forwarding references, so compute() must first materialize a temporary Value to bind to the function parameter

PERTAIN_TORootCause

It seems the `forward()` always do a `move`. — for(auto &&data : rhs) { lhs.push_back(std::forward(data)); }. Tension: I want to make a perfect forward `operator+=` so that `a += generate()` will move elements from the `generate()` but `a += b` will copy elements from `b`. Outcome: `auto && data` is deduced as `Data & data`;.

PERTAIN_TOSolution

I think this could work: — template DataList & operator+=(DataList &lhs, T &&rhs) {. Tension: `a += generate()` will move elements from the `generate()` but `a += b` will copy elements from `b`. Outcome: if constexpr (std::is_rvalue_reference_v) lhs.emplace_back(std::move(data)); else lhs.emplace_back(data);.

PERTAIN_TORootCause

I would like to refer to `Fi` sometimes — function template `ARGS_COUNT`. Tension: instead of bloating function definition with `std::floating_point auto` and `decltype`ing after. Outcome: It is possible to provide a more succinct "skeleton" by using `auto` for parameters types.

PERTAIN_TOSolution

Ways to write programs that clearly indicate their desired computations, both to the compiler and to future readers of the source code — these days, that is less important. Tension: it remains important to give programmers expressive power. Outcome: So features like the conditional operator remain useful in the language.

PERTAIN_TORootCause

With as-if rule, similar code might generate identical code — from a language point of view in C or C++. Tension: Ternary operator use the common expression, whereas if-else variant use unrelated branch. Outcome: compiler might generate identical code for both.

PERTAIN_TORootCause

So when C++23 speaks of the C standard, it speaks of C17. — If you peek into the C++23 standard chapter 2 "normative references". Tension: C23 the header is indeed empty. Outcome: Which has the same implementation of stdalign.h and similar headers as C11 had.

PERTAIN_TORootCause

Such mechanisms typically use a mutex. Tension: taking a mutex is prohibited in an interrupt. Outcome: no threads run to release the mutex during the interrupt.

PERTAIN_TOSolution

the answer to your question is no, just no — Dynamic memory allocation from the system heap of any kind whether by `new` or `malloc()` is unsafe in an interrupt. Tension: heap operations of any kind are not intrinsically thread safe or reentrant.

PERTAIN_TORootCause

using `reinterpret_cast` the way you are is undefined behavior — Also the byte representation of a `float` might differ among different machines. Tension: Another issue with changing machines could be endianness. Outcome: this solution also does not cover it.

PERTAIN_TORootCause

no managed GC pauses, no hidden runtime costs. Tension: fine-grained control over inlining, allocation, and object lifetime. Outcome: C++ lets teams avoid unpredictable pauses and tune worst-case latency.

WRITTEN_INSolution

Use `std::views::as_rvalue(rhs)` for rvalue inputs and `lhs.append_range(rhs)` for lvalues

Capture calls by reference in the lambda so increments affect the original counter

A simple way to do this is with a variadic template and a fold expression. — for any mismatch in size. Tension: I have 4 but that might go up. Outcome: return ((first.size() == rest.size()) && ...);.

serializeOutPutString(lxb_dom_interface_node(document),html); — QFile file("reportUseLexbor.html");. Outcome: QTextStream out(&file);.

you can rely on `std::get` and the `std::tuple` machinery — if you want to access the nth argument. Tension: Using a variadic template should make it possible to have more readable code. Outcome: you could use some alias that retrieves the required index from a `std::tuple` defined in the template parameters.

This is what gets compiled — with the correct mangled name. Tension: the target address defined inline in the C++ file. Outcome: This will still result in thunks, but those thunks will only consist of a single `jmp` instruction to the actual function address.

WRITTEN_INSolution

Using naked function thunks — This also works for constructors / destructors / class methods in general. Tension: with no thunks. Outcome: declare the functions as naked and directly jump to the absolute address where it is defined in the executable.

WRITTEN_INQuestion

Why do game developers prefer C++?

WRITTEN_INComponent

gold

OCCURS_INProblem

error: 3 names provided for structured binding — for (const auto& [index, key, value] : std::views::enumerate(histogram)). Tension: note: while 'const std::tuple&>' decomposes into 2 elements.

OCCURS_INProblem

Shadcn UI components rendered in an existing Create React App look different from the official shadcn examples after manual installation. Disabling Tailwind preflight caused the styling to be inconsistent and not match the expected design.

OCCURS_INProblem

Error: Cannot find module '../lightningcss.win32-x64-msvc.node' — failed to load config from C:\Users\user\Desktop\sann\ERP\vite.config.ts. Tension: error when starting dev server. Outcome: I tried all the solutions on the internet but the problem remained the same.
