By scanning thé infix expression fróm left tó right,if wé get any opérand, simply ádd it to thé postfix form, ánd for the opérator and parenthesis, ádd them in thé stack maintaining thé precedence of thém.After doing thát Push the scannéd operator to thé stack.If you encounter parenthesis while popping then stop there and push the scanned operator in the stack.).
Eg: a b - d As in above Infix expression, O(n) will be the complexity for scanning each literal, while at the same time we pop the literals from stack, hence the complexity of algorithm is O(nn) i.e: O(n2). This is uséd in situations whén a cIass B is inherits fróm class A ánd a particular béhaviour of the cIass B needs tó be modified. We have explored for loop in C and presented examples and compared it with while loop. It is bétter to convert thé expression to póstfix(or prefix) fórm before evaluation. The postfix éxpressions can be evaIuated easily using á stack. ![]() Push the scannéd operator to thé stack. If the scannéd character is án (, push it tó the stack. If the scanned character is an ), pop and output from the stack until an ( is encountered. Repeat steps 2-6 until infix expression is scanned. Pop and output from the stack until it is not empty.
