C++ write a function that can simplify algebraic string containing + and – operators Example: A-(-B+C) output: A+B-C A-(-(-B-C)) output: A-B-C
Added by Michael A.
Step 1
We must write a C++ function that simplifies algebraic strings containing only + and - operators and parentheses. The rule: a minus sign before a parenthesis flips the signs of everything inside that parenthesis. Examples: A-(-B+C) -> A+B-C A-(-(-B-C)) -> A-B-C Show more…

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 MUL T, C, D ADD X, X, T The Postfix would be AB+CD*+ The stack would be: PUSH A onto the stack PUSH B onto the stack ADD (pop A & B, add them, and push the answer back on the stack) PUSH C onto the stack PUSH D onto the stack MUL (pop C & D, multiply them, and push the answer back on the stack) ADD (pop X & T, add them, and push the answer back on the stack) POP X off the stack It is important to note that operational hierarchy dictates that we first perform all arithmetic inside inner parentheses, then inside outer parentheses, then do multiplication and division operations before addition and subtraction operations.
