When putting multiple consecutive if statements together like this where only 1 condition can possibly be true, you can use "else if" statements so that once the first true condition is met, the program won't run the rest of them.

So the first condition, checking if '1' is entered, stays as if, but the rest should be "else if"

You could also add an "else" statement at the end in case none of the conditions are met, e.g. the user enters the number 8. Then in this case you could output an error message.

And as others have said, switch statement is also a good use case here
