Infix: An expression is called the Infix expression if the operator appears in between the operands in the expression. Simply of the form (operand1 operator operand2). Example :(A+B) * (C-D) Prefix: An expression is called the prefix expression if the operator appears in the expression b...

An infix expression is rewritten as a prefix expression using a macro. The operator precedence rules were taken from Wikipedia. Any function calls should generally have parens around the arguments and not the function name. Aliased unary operators (as outlined below) do not need parens however....

Prefix expression (or Polish Notation ) An expression is said to be in prefix notation if the operators in the expression are placed before the operands on which the operator works. For example, +a*bc Precedence Order and Associativity of Operators The precedence order of operators is given in...
