Solution

A postfix expressions are the one which are easily read and evaluated by the computer. The postfix expressions will not have a braces as part of them. In the postfix expression, the binary operator which operates on 2 operands, will be placed after both the operands, and that is why it is called POSTfix. The operator will be post the operands. The simple logic for postfix evaluation is, if it is an operand push it to stack, and if it is an operator, pop the top 2 elements from the stack, and apply the operator. The compiler usually stores the expression in postfix format so that, the computer can evaluate these expressions faster.

An infix expression the one which is easily read and understood by the human. In the infix expression, the binary operator which operates on 2 operands, will be placed in between both the operands, and that is why it is called INfix. The operatored will be In between the operands.
