Programming | MCQs

Explanation

Nested loops are loops placed inside another loop.

It allowing complex iteration through multi-dimensional data structures.

They are commonly used for tasks like processing matrices or multi-level data.

Explanation

Procedural languages are also known as third-generation languages (3GLs).

Examples of third-generation languages include C, C++, Java, FORTRAN, and PASCAL.

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

BASIC (Beginner's All-Purpose Symbolic Instruction Code) is a high-level programming language designed for beginners to learn programming easily.

It was developed in the 1960s to make computer programming accessible to non-experts.

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

Algorithm and Flowchart are tools used to:

• Define a problem
• Break it down into smaller steps
• Logically organize those steps
• Visually represent the process

They help to:

• Specify the problem completely and clearly
• Identify the steps needed to solve the problem
• Understand the logical flow of the solution
• Communicate the solution to others

Explanation

High-level languages (e.g., Python, Java, C++)

They are machine-independent because they are designed to run on different hardware with minimal modifications.

James Gosling is well known as the father of Java. 2.

The first version of Java was released on 23 May 1995

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

In C language, printf() function is used to print formatted output to the standard output stdout (which is generally the console screen).

The printf function is a part of the C standard library and it can allow formatting the output in numerous ways.
