Difference between Algorithm, Pseudocode and Program

What is an algorithm?

• A type of computer hardware

• A specific programming language

• A machine-readable set of instructions

• A well-defined, step-by-step procedure to solve a problem

What is pseudocode?

• A high-level programming language

• A simpler version of programming code in plain English

• A type of algorithm

• Machine code that computers understand

What is a program?

• Exact code written in a specific programming language

• A flowchart describing the steps of an algorithm

• A detailed description of a computer's hardware

• A method for encrypting data

How can algorithms be expressed?

• By using pseudocode exclusively

• Using natural language, flowcharts, etc.

• Through machine code

• Using specific programming languages only

What is NOT true about pseudocode?

• It does not have a specific syntax

• It can include control structures like 'If-then-else'

• It is used to represent algorithms

• It can be executed on a computer

What is the main purpose of an algorithm?

• To serve as a specific programming language

• To provide a solution to a problem in form of steps

• To directly interact with computer hardware

• To encrypt data

Which of the following is true about a program?

• It is a graphical representation of an algorithm

• It is written in plain English

• It can only be written after a pseudocode is developed

• It is a set of instructions that the computer follows

What is the relationship between an algorithm and pseudocode?

• Pseudocode and algorithms are the same

• Algorithms are used to convert pseudocode into machine code

• Pseudocode is used to represent an algorithm

• An algorithm is a type of pseudocode

Which of the following is NOT a characteristic of pseudocode?

• It allows for the inclusion of control structures

• It can be understood by programmers familiar with different languages

• It is simpler than actual code

• It has a specific syntax like programming languages

What is the first step in the linear search algorithm as described?

• Return the index if x matches with an element

• Start from the leftmost element and compare x with each element

• Encrypt the data before searching

• Translate the algorithm into machine code
