Infix to Postfix Conversion using Stack in C Conversion of Infix to Postfix can be done using stack. The stack is used to reverse the order of operators. Stack stores the operator because it can not be added to the postfix expression until both of its operands are added. The precedence of...

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. The following is my code: #include<iostream>...
cout <<"input the infix expression:(you must input # to stop input)"<< endl; LinkStack* SOPTR =newLinkStack; LinkStack* SOPND =newLinkStack; evaluate(SOPTR, SOPND); return0; }

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. ...

The computer cannot differentiate the operators and parenthesis easily, that's why postfix conversion is needed. 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...
