- Enables the full control over the rendered HTML.
- Provides clean separation of concerns(SoC).

- Following the design of stateless nature of the web.
- RESTful urls that enables SEO.

wqking ยท 2y Yes Qt is worth learning. Not only it’s used a lot in C++ world, but also you can learn a lot of good architecture and OOP design in Qt, which is more valuable than Qt itself.
How many C are in a Qt?
This calculator provides conversion of quarts to cups and backwards (c to qt). 1 US quart ( qt) = 4 US cups ( c) = 0.25 gallons (gal) = 2 US pints (pt) = 32 US fluid ounces (fl. oz.) = 192 US teaspoons (tsp) = 64 US tablespoons (tbsp) = 946.352946 milliliters (ml) = 0.946352946 liters (l).
Does Qt have a C interface?
You cannot do either of these things with templates. C++ with the moc essentially gives us the flexibility of Objective-C or of a Java Runtime Environment, while maintaining C++’s unique performance and scalability advantages. It is what makes Qt the flexible and comfortable tool we have today.
