SOLVED:(Infixs to-Posfix Conversion) Stacks are used by compilers to help in the process of evaluating expressions and generating machine language code. In this and the next exercise, we investigate how compilers evaluate arithmetic expressions consisting only of constants, operators and parentheses. Humans generally write expressions like 3 4 and 7 / 9 in which the operator (4 or / here ) is Written between its operands - this is called infix notation. Computers "prefer" postfix notation in
