DataTable has a Compute method that allows you to write this: var result = new DataTable().Compute(“2-3/4*12”, null); Note that this is limited to simple math expressions. Other option consist in using a dynamic language in the DLR such as IronPython and IronRuby. Check-out this post: var engine = new IronPython.Hosting.PythonEngine(); double result = pythonEngine.EvaluateAs<double>(“2-3/4*12”); You … Read more

Well your first problem is your ‘main’ method int main() { int getFirstInteger(int userInput) return 0; } The syntax is incorrect (should be lined ended with a semi-colon). And you should be passing an int. So it could be modified to this int main() { int j = 1; getFirstInteger(j) return 0; } But it’s … Read more

The floor division // rounds the result down to the nearest whole number (data type = integer) and r as an integer will be 0 when interest is <100. You can see what happens with top if r equals 0. Same thing with fraction and the // operator. Use round to round the numbers. p … Read more
If the goal is truly to have a complex number calculator, and not to complete a school assignment or other exercise with some arbitrary restrictions, then you should use std::complex and do not reinvent the wheel. For what it’s worth, the constructor of std::complex takes two arguments, both with default values. Not mentioning templates, std::complex< … Read more
