Evaluate a short algebraic expression using code with three-operand instructions. the expression should have a minimum of three operands and 2 operators. operands may be alpha or numeric.
you may only use registers a through f, plus x and t.
registers a through f may not be changed, i. e. their values are fixed.
register t may be used as a temporary register, and register x must contain the final answer.
show the postfix for the expression, and then use a stack to evaluate the expression.
as an example, consider x=a +b + c * d
the three-operand instructions would be:
add x, a, b
