Chained execution
You write code, run it, and read the output. That output feeds the next stage. Four hops in, we ask for one thing: the final printed value.
tests: reasoning about your own program's state
Ascent · Competition syllabus
Know the language. Understand the machine.
Round 1 tests C++ proficiency, puzzles and debugging. Later rounds move from individual language fluency to team implementation and real toolchain work.
Syllabus · Round 1 · Proficiency, puzzles & debugging
The language.
Language core
- variables, objects & initialization · designated initializers · the most vexing parse
- keywords & identifiers
- literals & expressions
- datatypes, operators & control flow
- pointers, references & const
- the auto keyword
- enum / enum class
- C-style arrays & std::array internals
Objects & lifetime
- the stack & the heap
- storage durations & object lifetimes
- OOP: class/struct · member functions · access specifiers · special member functions
- function & operator overloading · overriding
- inheritance · dynamic polymorphism · the diamond problem · virtual
- static_cast · dynamic_cast · bit_cast
- move semantics · value categories · perfect forwarding · the rule of five
- unique_ptr & shared_ptr internals
Behavior & correctness
- UB · unspecified · implementation-defined · erroneous behavior
- error handling: std::exception · std::optional · std::expected
- floating-point pitfalls — why never ==
- debugging fundamentals
Generics & compile time
- generic types · type & non-type template params · variadic packs
- project: implement a custom Matrix
- constexpr vs consteval
- lambdas
Syllabus · Round 1 · Continued
The library & the machine.
Containers & internals
- iterator categories
- hashing & hash functions · map / unordered_map · set / unordered_set
- std::string internals & SSO
- std::vector internals · vector::reserve
Memory & the machine
- struct layout · alignment · padding · alignof / alignas
- cache lines & false sharing *
- atomics *
- branch misprediction

Live graph match
A target curve is on screen. You code the equation; the plot re-renders as you type. Submit when it matches.

Syllabus · Rounds 2 & 3 · Outline
Beyond the language.
The later-round scope is intentionally directional. Detailed topic lists will be published only when the competition design is locked.
Round 2 · Group
The build.
Implementation-heavy and group-based. Core CS fundamentals, executed as a team under a clock rather than recalled.
- · format: teams
- · axis: implementation depth
- · scope: core CS fundamentals
topic list pending — not for publication
Round 3 · Onsite
The toolchain.
Mastery of the language and everything around it. Judged on how you work, not only on what you submit.
- · language mastery
- · build systems
- · profiling
- · debugging
