which type of mobile app is built using one codebase for android and ios?
o a. native app
b. browser app
o c. cross - platform app
d. desktop app

Explanation:

• Question 19: A web app is designed to run directly inside a browser (mobile or desktop). Native apps are installed on the device, hybrid apps combine native and web - like elements but are still installed, and desktop apps are for desktop operating systems.
• Question 20: Cross - platform apps are built using a single codebase that can be deployed to multiple platforms like Android and iOS. Native apps are platform - specific, browser apps run in browsers (not the same as cross - platform in terms of codebase reuse for different OSes on mobile), and desktop apps are for desktops.

Answer:

• Question 19: B. Web app
• Question 20: C. Cross - platform app
