Today I Learned - Day 6 [틱택토 제작하기]

금일은 C#의 기본 문법에 대해서 공부하였습니다. 얼마 전 문법 톺아보기로도 한번 접했기도 한 지라, 전체적으로 복습한다는 느낌에 추가로 스파게티 코드 예방을 위해 '쉽게 알아볼 수 있게끔 하는 것'에 주의하여 작업했습니다.

 

코드

int[,] board = new int[3, 3];
bool turnInit,  turnPlayer;

turnInit = (new Random().NextDouble() < 0.5f);
turnPlayer = turnInit;

    if (result == 1)

        break;
    }
