isWhitespace()

설명

문자가 공백(white space)인지 분석합니다. white space란 스페이스, formfeed ('\f'), newline ('\n'), carriage return ('\r'), 수평 탭 ('\t'), 그리고 수직 탭 ('\v')을 말합니다. thisChar가 공백 문자이면 true를 반환합니다.

문법

isWhitespace(thisChar)

매개변수

  • thisChar : 변수. 허용되는 자료형: char

반환값

  • thisChar가 공백 문자이라면 true를, 아니라면 false를 반환합니다.

예제 코드

char myChar; void setup() { Serial.begin(9600); myChar = ' '; Serial.print(myChar); Serial.print(": "); if (isWhitespace(myChar)) // tests if myChar is a space character Serial.println("The character is a space or tab"); else Serial.println("The character is not a space or tab"); myChar = '\t'; Serial.print(myChar); Serial.print(": "); if (isWhitespace(myChar)) // tests if myChar is a space character Serial.println("The character is a space or tab"); else Serial.println("The character is not a space or tab"); myChar = 'A'; Serial.print(myChar); Serial.print(": "); if (isWhitespace(myChar)) // tests if myChar is a space character Serial.println("The character is a space or tab"); else Serial.println("The character is not a space or tab"); } void loop() {}
