下列给定函数fun的功能是:用冒泡法对6个字符串进行升序排列。 #include #include #define MAXLINE 20 fun ( char *pstr[6]) { int i, j ; char *p ; for (i = 0 ; i < 5 ; i++ ) { for (j = i + 1, j < 6, j++) { if(strcmp(*(pstr + i), *(pstr + j)) > 0) { p = *(pstr + i) ; /**************found**************/ ____________________ *(pstr + j) = p ; } } } } main( ) { int i ; char *pstr[6], str[6][MAXLINE] ; for(i = 0; i < 6 ; i++) pstr[i] = str[i] ; printf( "\nEnter 6 string(1 string at each line): \n" ) ; for(i = 0 ; i < 6 ; i++) scanf("%s", pstr[i]) ; fun(pstr) ; printf("The strings after sorting:\n") ; for(i = 0 ; i < 6 ; i++) printf("%s\n", pstr[i]) ; } A. *(pstr + i) = pstr + j ; B. *(pstr + i) = *pstr + j ; C. *(pstr + i) = *(pstr + j) ; D. *(pstr + i) = pstr + *j ;
