Line 117 calls a function with 2 arguments.
Line 13ff defines a function with zero arguments.

2 is not equal to 0.

For some reason you pass the data to alldata(...) not addition(...).

Line 6 unfortunately compiles (it should at least warn) but is invalid.
The lines 9/10 causes undefined behavior because n has no size.

thank you all guys

calculator class could have a constructor that takes 2 args and sets n from them.

L69 - this could be coded using < || > rather than having tests for each specific correct value.

Also for cases where you input a choice and then process depending upon the choice a switch statement is often used. The default case being used for input error.

Check your Boolean logic in line 49. That should be &&, not ||.
