First Run: Enter Infix expression : A+(B*C-(D/E^F)*G)*H Postfix Expression: ABC*DEF^/G*-H*+ Second Run: Enter Infix expression : (3^2*5)/(3*2-3)+5 Postfix Expression: 32^5*32*3-/5+ Related Tutorials Working with Hexadecimal values in C programming language ...
First, we have to fix the precedence of the expression. To convert the infix expression to its postfix expression, we have to take care of the following conditions: If the characters are in between 0-9 or a-z or A-Z, then we insert them to another array. If there is “ ( ” th...

CONVERSION OF INFIX EXPRESSION TO POSTFIXpost fix to infix
Infix expression is a+b*c+d then postfix expression is abc*+d+: a is operand (output it) //output=a + is operator (push it in stack) //stack=+ b is operand (output it) //ab * is operator and having high precedence than +, (push it in stack) //stack=+* ...
Output − Convert infix expression to postfix form. Begin initially push some special character say # into the stack for each character ch from infix expression, do if ch is alphanumeric character, then add ch to postfix expression else if ch = opening parenthesis (, then push ( into stack...
Given an infix expression, convert it to the postfix expression. Assume that the infix expression is a string of tokens without any whitespace. For example, Input:A*B+C Output:AB*C+ Input:(A+B)*(C/D) Output:AB+CD/* Input:A*(B*C+D*E)+F ...
