Programming Language | MCQs

Explanation

In C programming, && is the logical AND operator, used to evaluate whether both conditions are true.

It differs from &, which is a bitwise AND operator.

Explanation

In C language, each statement ends with a semicolon (;) to indicate the end of an instruction.

This helps the compiler understand where one statement ends and the next begins.

Explanation

Low-level languages (like assembly language) are close to machine code and require deep understanding of hardware structure.

They offer more control over hardware but are complex and hardware-specific.

Explanation

Grace Hopper is credited with inventing the first compiler, which she called A-0, in 1952.

Hopper's A-0 compiler was operational on the Univac computer.

Explanation

In computer science, the levels of representation are typically shown from high-level to low-level as:

• High-level: Software (e.g., C++, COBOL, JAVA)
• Low-level: Hardware (e.g., machine code, assembly language)

Explanation

A compiler translates high-level programming language (like C or Java) into low-level machine code.

It allowing the program to be executed by a computer's processor.

Explanation

Computers primarily use binary language.

It consisting of 0s and 1s, to process and execute commands.

Explanation

JavaScript is a programming language that can be used to create interactive websites.

Explanation

Explanation

Machine language is a low-level language

It consists of binary code (0s and 1s) that is directly executed by a computer's CPU.

High-level languages like C, Java, and Fortran are designed to be more user-friendly and abstracted from machine code.
