Create a mini calculator program that takes input from user as an infix sequence of operators and operands. No need for GUI. A console application would be fine. The implementation should use a Stack object. I'm interested in an efficient algorithm rather than the UI.

I am very proficient in c, c++. I have 15 years c++ developing experience now, and I have worked for 5 years. My work is online game developing, and mainly focus on server side, the language is c++ under linux. I used c++ to make many great projects, for example, I made the tools which can convert java files to c++ scripts which has the same effect, of course garbage collection included. I also made our own mobile game using c++, I even can show you the demo of client. Trust me, please let expert help you.

the best way to evaluate a mathematical expression is to first change the postfix notation and then evaluate it. This is part of the main function and sample output. int main (int argc, const char* argv[]) { if (argc > 1) { std::cout << "Eval= " << argv[1] << std::endl; std::string posfix = fposfix(argv[1]); std::cout << "postfix= " << posfix << std::endl; std::cout << "Result= " << fevaluate(posfix) << std::endl; } else { std::cout << "Type " << argv[0] << " expr" <<std::endl; } } Eval= 6 * ( 5 - 3 ) postfix= 6 5 3 - * Result= 12 Eval= 3 + 4 * 2 / ( 1 - 5 ) ^ ( 2 ^ 3 ) postfix= 3 4 2 * 1 5 - 2 3 ^ ^ / + Result= 3.00012

I read your project description and I think I can give you the well documented code. I already have a written code which converts infix string to postfix notation and then evaluates it using STL stack in C++.

Can you provide you a C++ function which takes inputs as Operand , operator Operand .... up to a maximum of predefined numbers of operands. stack can store the result as soon as equal sign is entered. This result will be stacked to resume the next set of operations on this result . Grouping of operations can also be provided.

It is very simple task, using reverse Polish notation. Two algorithms will be used - 1) transform infix notation into reverse notation 2) calculate expression using reverse notation both of them use stack I have questions: 1)what kind of operands you mean- integer, floating point or other 2) what operations must be included in calculator - only arithmetic or something else.

It can be my debut on the freelancer.com. :) The work seems like a usual programming task on the first year of CS undergraduate programme.

I actually have done this type of program before in one of my CS classes. The project has already been completed. User enters the expression and it uses the stack to convert and then output new expression.
