💡Pseudocode

Pseudocode is a high-level description of a computer program or algorithm that uses simple, English-like statements to outline the basic logic of the program. It is not written in a specific programming language but serves as a clear outline of the steps needed to solve a problem or complete a task. In the video, pseudocode is presented as a crucial tool for programmers to think through the logic of their program before coding, which helps in identifying potential issues and ensuring the program works as intended.

💡Program

A program in the context of the video refers to a sequence of instructions that a computer can execute to perform a specific task or solve a problem. The video emphasizes the importance of planning a program using pseudocode to ensure efficiency and accuracy. For example, the script mentions writing a program that adds two numbers, which is a simple task but requires a clear plan to execute correctly.

💡Algorithm

An algorithm is a set of rules or steps to be followed in calculations or other problem-solving operations, especially by computers. The video discusses pseudocode as a means to describe algorithms in a way that is understandable and can be easily translated into actual code. The script uses the addition of two numbers as an example of a simple algorithm that can be outlined in pseudocode.

💡Logic

Logic, in the context of programming, refers to the rational arrangement of ideas or statements that form the basis of a program or algorithm.
