Introduction to C++ Operators: Detailed Explanation of Arithmetic, Comparison, and Logical Operators

C++ operators are fundamental tools for data processing and logical judgment, categorized into arithmetic, comparison, and logical operators. Arithmetic operators include +, -, *, /, and %, where division (/) truncates decimals for integer division, and the modulus operator (%) is only applicable to integers with a remainder sign consistent with the dividend. Increment (++) and decrement (--) operators have pre-increment/post-increment and pre-decrement/post-decrement forms, respectively, with the former modifying the variable before use and the latter using the variable before modification. Comparison operators return boolean values (true/false) to judge relationships between values, and it is important to distinguish between == (equality comparison) and = (assignment). Logical operators combine conditions: && (logical AND, short-circuit evaluation), || (logical OR, short-circuit evaluation), and ! (logical NOT). Mastering these operators is crucial for subsequent learning and requires practice to solidify.
