Expression Evaluation
Expression evaluation is a fundamental concept in computer science and programming that involves computing the value of an expression based on its syntax, operators, and operands. It is a core process in programming languages, compilers, and interpreters, where expressions—combinations of variables, constants, and operators—are resolved to produce a result. This process includes parsing the expression, applying operator precedence and associativity rules, and handling data types and conversions.
Developers should learn expression evaluation to understand how code executes at a low level, which is essential for debugging, optimizing performance, and writing efficient algorithms. It is particularly important when working with compilers, interpreters, or custom scripting engines, as it underpins the execution of mathematical calculations, logical operations, and conditional statements in any programming language.
