8楼 你还有脸说自己学了一年？？？ 我运行正常！！(编译环境：DevC++4.9.9.2 + winXP ) ps:我学了一个月. 稍作修改如下： #include <stdio.h> #include <stdlib.h> #include<ctype.h> const char dos_line_end = '\n'; /* actually "\r\n" */ const char unix_line_end = '\r'; const char mac_line_end = '\n'; int main(int argc, char *argv[]) { const char default_line_end = #if defined(__UNIX__) unix_line_end; #elif defined(WIN32) dos_line_end; #else mac_line_end; #endif int c; char line_end = default_line_end; int word_count = 0; int line_count = 0; int in_a_word = 0; /* false */ FILE *tf; printf("[+] Word Count by akuma@tds\n"); system("pause"); if (argc < 2) { printf("[+] usage: %s file [type]\n", argv[0]); printf(" file: the file to be counted\n"); printf(" type: u for unix style (\\r), d for dos style (\\r\\n)," " m for Mac OS (\\n)\n"); system("pause"); return 1; } if (argc > 2) switch(argv[2][0]) { case 'u': case 'U': printf("[-] unix style: \\r will be count as the end of line\n"); line_end = unix_line_end; break; case 'd': case 'D': printf("[-] dos style: \\r\\n will be count as the end of line\n"); line_end = dos_line_end; system("pause"); break; case 'm': case 'M': printf("[-] mac os style: \\n will be count as the end of line\n"); line_end = mac_line_end; system("pause"); break; default: printf("[-] ingorne unknown type switch: %c\n", argv[2][0]); system("pause"); } if (NULL == (tf = fopen(argv[1], "r"))) { printf("[-] error on opening file: %s\n", argv[1]); system("pause"); return 2; } while (EOF != (c = fgetc(tf))) if (line_end == c) in_a_word = 0, line_count++; else if (isspace( c )) in_a_word = 0; else if (!in_a_word) in_a_word = 1, word_count++; if (line_count || word_count) line_count++; fclose(tf); printf("[-] File: %s\n", argv[1]); printf(" contains: %d word(s) in %d line(s).\n", word_count, line_count); system("pause"); return 0; } 编译运行结果： [+] Word Count by akuma@tds 请按任意键继续. . . [+] usage: C:\Dev-Cpp\complied\character_count.exe file [type] file: the file to be counted type: u for unix style (\r), d for dos style (\r\n), m for Mac OS (\n) 请按任意键继续. . . 使用结果： C:\>\Dev-Cpp\complied\character_count.exe C:\Dev-Cpp\complied\character_count.cp p d [+] Word Count by akuma@tds 请按任意键继续. . . [-] dos style: \r\n will be count as the end of line 请按任意键继续. . . [-] File: C:\Dev-Cpp\complied\character_count.cpp contains: 262 word(s) in 86 line(s). 请按任意键继续. . . |

9楼 这两个写反了： const char unix_line_end = '\r'; const char mac_line_end = '\n'; 应该改为： const char unix_line_end = '\n'; const char mac_line_end = '\r'; |
