I would suggest using overloaded operators if you're gonna use a class. Oh, and a few other things: * Functions that perform the lowest level operations (in this case, *Function()) should not perform I/O. I/O should only be performed in functions very close to the highest level, or...
case '9': res = 9; break; default: cout << "ChToI() error: " << ch << endl; exit(-1); // stop the program } return res; } char NToCh(int n) // number to char { char res = '0'; switch (n) { case 0: res = '0'; break; ...
case 6: cout << "thanks for using this calculator!" << endl << endl; cin.get(); return 0; break; } cout << "would you like to restart(y or n)"; cin >> again; }while(again == 'y' ||again == 'Y'); cin.get(); return...
Switch to the Calculator.cpp file in the editor window. Replace the contents of Calculator::Calculate(double x, char oper, double y) with: C++ คัดลอก double Calculator::Calculate(double x, char oper, double y) { switch(oper) { case '+': return x + y; case '-':...

Each time you press "Solve", Storage.cpp saves previous page of text in EEPROM (if it has changed). Holding down the Left key loads the previous saved file so it acts like an "undo" key. Attachments Step 7: The Case The case is 3D-printed. The STL files can be downloaded (below)...
