If the polynomial object contains no term whose power matches InputPower , this function will return 0. Displays polyC . A postfix expression has its operators after operands. Infix expressions use operator priority in computing the value of an expression. Postfix expressions never use parentheses.
Some calculators require entry of expressions in postfix form.
Also, compilers usually convert infix expressions to a postfix equivalent before generating code. Here is an algorithm for converting simple infix expressions to postfix. Expressions will be in valid infix form with tokens separated by one or more spaces. Each preceding line will contain a separate, valid infix expression to be converted. One constructor for this class will have a parameter that specifies a file from which to load data.
