# container-inside-loop Finds places defining containers inside loops. Defining them outside the loop and using `resize(0)` will save memory allocations. #### Example // This will allocate memory at least N times: for (int i = 0; i < N; ++i) { QVector<int> v; (...) v.append(bar); (...) } // This will reuse previously allocated memory: QVector<int> v; for (int i = 0; i < N; ++i) { v.resize(0); // resize(0) preserves capacity, unlike QVector::clear() (...) v.append(bar); (...) } #### Supported containers `QList`, `QVector` and `std::vector`
