The `switch` statement jumps to a case label based on an integral or enumeration value.\\n\\n---\\n\\n## Example: `if`‑`else` and `switch`\\n```cpp\\nint score = 85;\\nif (score >= 90) {\\n std::cout << \\\"Grade A\\\" << '\\\\n';\\n} else if (score >= 80) {\\n std::cout << \\\"Grade B\\\" << '\\\\n';\\n} else {\\n std::cout << \\\"Grade C or lower\\\" << '\\\\n';\\n}\\n\\nenum class Color { Red, Green, Blue };\\nColor c = Color::Green;\\nswitch (c) {\\n case Color::Red: std::cout << \\\"Red\\\\n\\\"; break;\\n case Color::Green: std::cout << \\\"Green\\\\n\\\"; break;\\n case Color::Blue: std::cout << \\\"Blue\\\\n\\\"; break;\\n default: std::cout << \\\"Unknown\\\\n\\\"; break;\\n}\\n```\\n\\n> **Tip:** With C++17 you can use `if constexpr` to conditionally compile branches based on compile‑time constants.\\n\\n---\\n\\n`switch` does **not** support `float` or `std::string` directly. Use `if‑else` or a `std::map` for those cases.","author":{"@type":"Person","name":"Mohit"},"publisher":{"@type":"Organization","name":"BraveProgrammer","logo":{"@type":"ImageObject","url":"https://braveprogrammer.vercel.app/logo.png"}}},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Courses","item":"https://braveprogrammer.vercel.app/learning"},{"@type":"ListItem","position":2,"name":"C++ Course","item":"https://braveprogrammer.vercel.app/learning/cpp-basics"},{"@type":"ListItem","position":3,"name":"Lesson 6: Control Flow – if, else, switch","item":"https://braveprogrammer.vercel.app/learning/cpp-basics?lesson=5"}]}]}
