什么时候在C ++中进行强制转换，编译时或运行时？

Question

c ++隐式强制转换/转换是在编译时还是在运行时发生？

int64 i64 = 1;
int8 i8 = static_cast<int8>(i64); // (1) explicit cast, when does this happen?
int32 i32 = i8; // (2) implicit cast,when does this happen?

[1] Do constant and reinterpret cast happen at compile time?

[2] Is static_cast<T>(...) compile-time or run-time?
