  2. Reverse Polish notation - Wikipedia

    en.wikipedia.org/wiki/Reverse_Polish_notation

    For example, to add 3 and 4 together, the expression is 3 4 + rather than 3 + 4. The conventional notation expression 3 − 4 + 5 becomes 3 (enter) 4 − 5 + in reverse Polish notation: 4 is first subtracted from 3, then 5 is added to it. The concept of a stack, a last-in/first-out construct, is integral to the left-to-right evaluation of RPN.

  3. Common operator notation - Wikipedia

    en.wikipedia.org/wiki/Common_operator_notation

    The operator precedence is a number (from high to low or vice versa) that defines which operator takes an operand that is surrounded by two operators of different precedence (or priority). Multiplication normally has higher precedence than addition, [1] for example, so 3+4×5 = 3+(4×5) ≠ (3+4)×5.

  4. Infix notation - Wikipedia

    en.wikipedia.org/wiki/Infix_notation

    Infix notation is more difficult to parse by computers than prefix notation (e.g. + 2 2) or postfix notation (e.g. 2 2 +). However many programming languages use it due to its familiarity. It is more used in arithmetic, e.g. 5 × 6. [1]

    */ /* This implementation does not implement composite functions, functions with a variable number of arguments, or unary operators. */ while there are tokens to be read: read a token if the token is: - a number: put it into the output queue - a function: push it onto the operator stack - an operator o 1: while ( there is an operator o 2 at the ...

  6. Binary expression tree - Wikipedia

    en.wikipedia.org/wiki/Binary_expression_tree

    Some of the common operators are × (multiplication), ÷ , + , − (subtraction), ^ (exponentiation), and - . The operators are contained in the internal nodes of the tree, with the numbers and variables in the leaf nodes. [1] The nodes of binary operators have two child nodes, and the unary operators have one child node.

  7. Operator (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Operator_(computer...

    Semantically operators can be seen as special form of function with different calling notation and a limited number of parameters (usually 1 or 2). The position of the operator with respect to its operands may be prefix, infix or postfix (suffix [1]), and the syntax of an expression involving an operator depends on its arity (number of operands ...

  8. Increment and decrement operators - Wikipedia

    en.wikipedia.org/wiki/Increment_and_decrement...

    In languages syntactically derived from B (including C and its various derivatives), the increment operator is written as ++ and the decrement operator is written as --. Several other languages use inc(x) and dec(x) functions. The increment operator increases, and the decrement operator decreases, the value of its operand by 1.

  9. Operators in C and C++ - Wikipedia

    en.wikipedia.org/wiki/Operators_in_C_and_C++

    All comparison operators can be overloaded in C++. Since C++20, the inequality operator is automatically generated if operator== is defined and all four relational operators are automatically generated if operator<=> is defined. [1]
