Programming Languages | MCQs

Explanation

VBA (Visual Basic for Applications) is used to produce macros.

VBA is a programming language owned by Microsoft and is integrated into most Microsoft Office applications

Explanation

In BASIC programming, CLS stands for "Clear Screen".

It is used to erase all output from the screen and start fresh.

Explanation

In C language, a compound operator combines an arithmetic operator with an assignment operator, e.g., +=, -=, *=, /=.

These are used to simplify expressions, like x += 5 means x = x + 5.

Explanation

The continue statement skips the remaining code inside the loop for the current iteration.

It then shifts control back to the beginning of the loop for the next iteration.

Explanation

High-level programming languages are commonly classified into three categories: procedural, object-oriented, and functional.

These categories are based on different programming paradigms that define how programmers structure and write code.

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)
