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...
