Learn how to reserve capacity ahead of time with std::vector in C++ for better performance on embedded targets.
// Example of reserving capacity in std::vector for embedded systems #include #include int main() { // Create a vector and reserve space for 100 elements std::vector myVector; myVector.reserve(100); // Verify the capacity and size std::cout << "Capacity: " << myVector.capacity() << std::endl; // Should output 100 std::cout << "Size: " << myVector.size() << std::endl; // Initially size should be 0 // Now let's add some elements for (int i = 0; i < 50; ++i) { myVector.push_back(i); } // Final size after adding elements std::cout << "Final Size: " << myVector.size() << std::endl; // Should output 50 return 0; }
