This topic comes under the application of stack data structure as stack data structure is used to perform conversions between these 3 expressions. What is an Expression? An Expression is a combination of symbols that can be numbers (constants), variables, operations, symbols of grouping and other punctuation written is a specific format/way. Depending on how the expression is written, we can classify it into 3 categories - 1) Prefix - An expression is called the prefix expression if the operator appears in the expression before the operands. Simply of the form (operator operand1 operand2). E.g. +AB 2) Infix - An expression is called the infix expression if the operator appears in the expression in between the operands. Simply of the form (operand1 operator operand2). E.g. A+B 3) Postfix - An expression is called the postfix expression if the operator appears in the expression after the operands. Simply of the form (operand1 operand2 operator). E.g.
