Computer science education cannot make anybody an expert programmer any more than studying brushes and pigment can make somebody an expert painter. Eric S. Raymond
Infix and postfix are the notations to write the expressions. The infix notation put operators in between the operands. The postfix notation put operators after their operands. Write a program convert from infix notation to postfix notation.
Infix (5 + 3) * 12 / 3
Postfix: 5 3 + 12 * 3 /
Infix : 1+3*4/5 Postfix : 134*5/+
