We have given an Arithmetic Expression and we have to write a program that converts the infix to postfix using stack in C. The Expression will be given in the form of a string, where alphabetic characters i.e a-z or A-Z denotes operands and operators are ( +, –, *, / ). Expres...

SAZZAD-AMT/Infix-to-Prefix-to-Postfix-Conversion-Assembly-code-by-c-program Star2 While we use infix expressions in our day to day lives. Computers have trouble understanding this format because they need to keep in mind rules of operator precedence and also brackets. Prefix and Postfix expressi...
I have written a C++ program to convert an infix expression to postfix expression using recursion. I would like to know if it can be improved if possible. Can we improve it by not usingastack? I am using avectorvector<char>as a stack here. ...
To convert infix expression to postfix expression, we will use the stack data structure. By scanning the infix expression from left to right, when we will get any operand, simply add them to the postfix form, and for the operator and parenthesis, add them in the stack maintaining the preced...
Convert Infix to Postfix Notation Initially we’ve astringS which represent the expression in infix format. Now we need a characterstack. *We’ll iterate through thestringS, from left to right. Whenever we encounter an operand we’ll print it. ...
