Pseudocode is a design notation used to represent the logic and structure of a computer program without specific programming syntax. It allows for more flexibility than actual programming languages and uses common descriptions of programming constructs like INPUT, OUTPUT, WHILE loops, and IF/THEN conditional statements. An example pseudocode solution is given for a program that asks the user to input a test score between 1 and 99, displaying an error if they enter an invalid value. Pseudocode is useful for planning programs before writing actual code as each line can later be directly converted to a programming language.
