The example in this chapter uses trees to translate expressions to postfix, prefix, and infix. Az ebben a fejezetben bemutatandó példa a kifejezéseket prefix, postfix vagy infix alakra hozza.Literature Instead, the operation uses the special character > (which is tokenized separately during ...
Infix expressions are, put simply, expressions written in the 'normal' way, with operators placed between operands. (1 + 2) * 3 is an example of an infix expression. This isn't the only way to write an arithmetic expression. Other options include prefix and postfix. A postfix expression ...
