I am making a codelock with three buttons. I am planning for it to be able to use the same button twice. Since i am using a counting system to verify if the code was put in the right way it counts that button twice. I need the code to be able know if the button is used twice in the code or not.
School project.
Here is my code. The "combination" can be defined by the user by changing the code in int code_1 - int code_6 and code_length is there cause the code does not know the length. x is an input i added to fill the blanks
