C Program for Evaluation of Postfix Expression C Program for Evaluation of Postfix Expression In this program we evaluate the Postfix Expression, using the stack. C Program for Evaluation of Postfix ExpressionIn this program we evaluate the Postfix Expression. C Program Examples. C Program to Evaluate POSTFIX Expression Using Stack, the program implemented with push and pop operations.
A postfix expression is a collection of operators and operands in which the operator is placed after the operands. My Mom S Best Friend there. That means, in a postfix expression the operator follows the operands. Postfix Expression has following general structure. Operand1 Operand2 Operator Example Postfix Expression Evaluation using Stack Data Structure A postfix expression can be evaluated using the Stack data structure. To evaluate a postfix expression using Stack data structure we can use the following steps.
• Read all the symbols one by one from left to right in the given Postfix Expression • If the reading symbol is operand, then push it on to the Stack. • If the reading symbol is operator (+, -, *, / etc.,), then perform TWO pop operations and store the two popped oparands in two different variables (operand1 and operand2).
