Programming | MCQs

Explanation

In computer systems, especially Windows, a drive is represented by a letter followed by a colon, like C:, D:.

This notation is used to identify different storage locations or partitions.

Explanation

Assembly language is a low-level language that uses mnemonics to represent machine-level instructions.

It is hardware-specific and closer to binary code, offering more control over hardware.

Explanation

Explanation

Business refers to organizational/commercial activities, not a programming structure.

Common Programming Concepts:

Condition: Used for decision-making (e.g., if-else statements).

Sequence: The order in which instructions are executed.

Loop: Repeats a block of code (e.g., for, while loops).

Explanation

User-defined functions are those that are created by the programmer to perform specific tasks.

Unlike pre-defined functions, they offer custom behavior and improve code reusability and structure.

Explanation

Arrays store elements in a sequential (linear) order, where each item has a fixed position (index).

They allow efficient access to elements using their index, making them a linear data structure.

Explanation

If, If-Else, and Switch are used to make decisions based on conditions in programming.

These are known as Conditional Statements because they execute code only if certain conditions are met.

Explanation

The switch statement is known as a selection statement because it selects one option from multiple possible paths based on the value of a variable.

It's commonly used for decision-making in programming.

Explanation

Scratch is a visual programming language where users create programs by dragging and connecting code blocks.

It is mainly used for educational purposes to teach programming concepts in a simple, interactive way.

Explanation

Integer data type stores whole numbers without decimals, ideal for values like 67, 100, etc.

It supports a range that easily includes numbers greater than 66.000 and doesn’t require decimal precision like float.
