A small startup is building a cross-platform desktop utility that must start instantly and run without requiring users to install a runtime. The team values fast development and frequent updates. Which language choice best meets these requirements?

C++, because it compiles to native code that runs directly on the OS.

Python, because it is interpreted and runs on any OS with Python installed.

Java, because it is object-oriented and widely used.

JavaScript with Node.js, because it is lightweight and cross-platform.

A developer writes a loop that should iterate over an array of 10 items. The code is: for (i = 0; i <= 10; i++) { process(array[i]); }. What is the likely result?

The loop processes all 10 items correctly.

The loop processes 11 items, causing an out-of-bounds error on the last iteration.

The loop processes 9 items, missing the last one.

The loop does not execute because the condition is false.

A startup is building a mobile app that needs to work offline and access device hardware like the camera and GPS. They have a small team with web development skills. Which approach is most cost-effective and efficient?

Use a compiled language like C++ for the app logic and a web view for the UI.

Use a cross-platform framework like React Native, which uses JavaScript.

Build a mobile web app using HTML, CSS, and JavaScript.

Develop a native app for each platform using Swift and Kotlin.

A company has a performance-critical application that must run on a specific hardware platform. They are willing to spend more development time to achieve the fastest possible execution. Which language type is most appropriate?

A compiled language like C, because it produces efficient machine code.

An interpreted language like Python, because it is easy to optimize.

A markup language like XML, because it is structured and fast.

A scripting language like JavaScript, because it runs in any browser.
