Calculator, Essay, Game Program in C++

Calculator, Essay, Game Program in C++

 

 

 

 

 

Calculator, Essay writing and Game all three features in a single C++ program. Yes we are doing now some fun with the C++ language. We will develop a C++ program which will ask the user to either perform calculation, Write Essay or play a game.

So just execute and understand this code and see what happens. One thing just keep in mind this program will run on Dev C++ IDE. If you are using some other compiler you have to modify the code for execution. So let’s go.

Code

            char choice;

            cout<<"\n\t\tPress C to open Calculator\n\t\tPress E to Write an Essay\n\t\tPress G to play a Game\n";
