이번 수업 코드에서 123d 처럼 정수+문자를 넣게 되면 scanf가 123은 정상적으로 입력받아 올바를 출력은하지만 d가 출력이 잘못 되어서

Please input a integer between 1 and 100.

Please input an integer and press enter.

123d

Your input 123 is integer.

wrong

Please input a integer between 1 and 100.

Please input an integer and press enter.

Your input - d - is not an integer. Please try again.

이런식으로 출력되는데 어떻게 해야하나요
