Infix to postfix conversion is a process used in computer science to transform arithmetic expressions written in infix notation (where operators are placed between operands) into postfix notation (where operators follow their operands), which is more suitable for stack-based evaluation. This conversion facilitates easier computation by eliminating the need for parentheses and operator precedence rules, allowing for straightforward evaluation using a stack data structure.

Arithmetic expressions are combinations of numbers, operators, and sometimes parentheses, used to perform calculations and evaluate values in mathematics and programming. Understanding the precedence and associativity of operators is crucial for correctly interpreting and solving these expressions.

arithmetic expressions

Infix notation is a common arithmetic and logical formula notation where operators are placed between operands, such as in 'A + B'. This notation is widely used in mathematics and programming languages for its readability and natural expression of operations, but it requires operator precedence and associativity rules to be properly evaluated by computers.

Postfix notation, also known as Reverse Polish Notation (RPN), is a mathematical notation in which operators follow their operands, eliminating the need for parentheses to denote operation order. This notation is particularly useful in computer science for stack-based calculations and is employed in certain calculators and programming languages to simplify expression evaluation.

Computation is the process of performing mathematical calculations or processing data by following a well-defined model or algorithm. It forms the foundation of computer science and is essential for the functioning of digital systems, enabling tasks from simple arithmetic to complex simulations and data analysis.

Parentheses are punctuation marks used to enclose information that is supplementary or tangential to the main text, allowing the writer to include additional details without disrupting the flow of the sentence. In mathematics, parentheses dictate the order of operations, ensuring that expressions within them are evaluated first, which is crucial for accurate calculations.

Operator precedence determines the order in which operators are evaluated in expressions, ensuring consistent and predictable results. Understanding these rules is essential for writing accurate and efficient code, as it affects how expressions are parsed and executed by programming languages.

Evaluation is a systematic process of determining the merit, value, or worth of something, often used to assess the effectiveness of programs, processes, or products. It involves collecting and analyzing information to make informed decisions, improve outcomes, and ensure accountability.

evaluation

A stack is a linear data structure that follows the Last In, First Out (LIFO) principle, where the last element added is the first to be removed. It is commonly used in scenarios like function call management, undo mechanisms in applications, and syntax parsing in compilers.
