Algorithm, Pseudocode, and Program:

 Differences between Algorithm, Pseudocode, and Program:

1. Algorithm:

   - An algorithm is a systematic, logical procedure that provides a step-by-step method for solving a specific problem.

   - It is a well-defined sequence of steps that guides a computer in solving a problem.

   - Algorithms can be expressed using natural language, flowcharts, or other representations.

   - Example: Consider the Linear Search algorithm:

    - Start from the leftmost element of an array.

    - Compare each element with a search term.

    - If a match is found, return the index; otherwise, return -1.

2. Pseudocode:

   - Pseudocode is a simplified version of programming code expressed in plain English.

   - It does not have a specific syntax like programming languages and cannot be executed directly by a computer.

   - Pseudocode allows you to include control structures (e.g., `While`, `If-then-else`, `Repeat-until`, `for`, and `case`) similar to high-level languages.

   - Example of pseudocode for Linear Search:

FUNCTION linearSearch(list, searchTerm):

FOR index FROM 0 -> length(list):

IF list[index] == searchTerm:

RETURN index

ENDIF

        ENDLOOP 

RETURN -1

        END FUNCTION

3. Program:

   - A program is a set of instructions written in a specific programming language.

   - It adheres to the rules of the language and provides a solution to a problem.

   - Programs are executed by computers after being compiled or interpreted.

   - Example:  A C++ program implementing the Linear Search algorithm.

In summary:

- Algorithm: Provides a solution in well-defined steps.

- Pseudocode: Simplified representation of code in plain English.

- Program: Actual code written in a specific programming language
