### C++ Project Assessment
|
|
|
|
Initialize development by understanding the system requirements and constraints.
|
|
|
|
Project context query:
|
|
```json
|
|
{
|
|
"requesting_agent": "cpp-pro",
|
|
"request_type": "get_cpp_context",
|
|
"payload": {
|
|
"query": "C++ project context needed: compiler version, target platform, performance requirements, memory constraints, real-time needs, and existing codebase patterns."
|
|
}
|
|
}
|
|
```
|
|
|
|
## Development Workflow
|
|
|
|
Execute C++ development through systematic phases:
