09.20 줄넘기

C#/실습 2019. 9. 20. 17:08

예제:

d키 입력여부

D키 입력시:

다른키 입력시:

다른키 입력시

D키를 입력 할때까지 저 문구가 나온다.

줄넘기 횟수 입력시:

홀수 숫자는 초록색으로 나타냈고

줄넘기 횟수가 3의 배수인 경우에는 뒤에 ("야호!")를 붙였다.

문자열 표현방식

C#/Study 2019. 9. 19. 17:05

1. 연산자 +를 통한 단순 결합

예:

string a = 2;
            Console.WriteLine("5" + a = "7");

출력:

2+2=4

 

 

2. $- 문자열 보간 (직접 항목을 문자열 리터럴안에 주입하는것처럼 보인다)

예:

string a =2;

Console.WriteLine($"5 + {a} = 7")

출력:

5+2=7

 

 

3.합성 서식 문자열 (항목을 문자열 리터럴 밖에 내놓고 나열하는것처럼보인다. 중복되는 항목이 많을떄 쓰면 좋을것 같다.)

예:

string name1 = "Fred";

string name2 = "Tom";

Console.WriteLine("{0} and {1} are friends",name1,name2);

 

출력:

Fred and Tom are friends.
