  1. Pointer , String & Array F.D

  2. Pointer & String • 문자열? • ‘/0’을 포함하는 문자의 집합 • 문자열의 저장 • 메모리에 연속적 저장. 끝에 ‘/0’ • 첫 글자의 시작 주소를 기억

  3. Pointer & String

  4. Pointer & String str str[0] = ? str[1] = ? str[4] = ?

  5. Pointer & String str • *(arr+i) = arr[i] ; • str[0] = *(str+0) = • str[4] = *(str+4) =

  6. Pointer & String str[1] = ‘g’;

  7. Pointer & String • str ; 변수영역 • str2 ; 상수영역

  8. Pointer & String • 서식문자 %s

  9. Pointer & Array

  10. +1 +1 arr[0]+1 arr[1]+1 +1 =arr+1

  11. Pointer & Array arr[0][2] = arr[0][4] = arr[0][5] = *(arr[0]+2) *(arr[0]+4) *(arr[0]+5)

  12. Pointer & Array arr[1][2] = arr[1][-1] = arr[1][-3] = *(arr[1]+2) *(arr[1]-1) *(arr[1]-3)

  13. Pointer & Array

  14. Pointer & Array

  15. Pointer & Array pArr

  16. Pointer & Array

  17. Pointer & Array pArr

  18. Pointer & Array pArr[0][3] = pArr[0]+3 pArr pArr[0]+3 = pArr[0][3]
