penny calculator

1) First, a simple calculator is computed using C # process-oriented Code. The Code is as follows: Try {console. writeline ("Enter the number A:"); string numbera = console. readline (); console. writeline ("Enter the calculated character" +,-, *,/""); string operater = console. readline (); console. writeline ("Enter the number B:"); string numberb = console. readline (); double strrusult = 0; If (operater = "+") {strrusult = convert. todouble (num

MVC patternThe main task of the model is to help developers solve a class of problems.The MVC pattern is primarily used to plan the development of your site in a basic structure.The servlet remembers to act as a controller layer.
