Computer evaluation of postfix Going left to right, –If you see a number, put it on the stack –If you see an operator, pop two numbers from the stack, do the operation, and put the result back on the stack (The top number on the stack is the operand on the right) The result i...
In the end, the result of the expression is left as the only element in the stack, which is popped and returned as the result of evaluation Algorithm for Evaluating a Postfix Expression opndstk=the empty stack; //scan the input string one element a time into symb while (not end of inpu...

The project contains algorithms that were implemented in my Data Structure & Algorithms course. Yes, I got marks for those. :P AlgorithmImplementations ├─ arithmeticExpressions │ ├─InfixEvaluation │ ├─InfixToPostfix │ ├─InfixToPrefix ...
While reading the expression from left to right, push the element in the stack if it is an operand. Pop the two operands from the stack, if the element is an operator and then evaluate it. Push back the result of the evaluation. Repeat it till the end of the expression. ...
2. Evaluation of Postfix Expressions Supported Mathematical Operators: +, - (binary), ~ (unary) *, /, ^ Supported Functions: sin, cos, tan, cot, sqrt, ln Description: The expression is evaluated using a stack for operands. 3. Graph Plotting Functionality: Computes an array of values ...
