关于fgets函数原理的一点疑问
已知在tmp路径下有一个words.txt （tmp/words.txt）文本内容：
Joe-Bob "Handyman" Brown
Jacksonville "Sly" Murphy
Shinara Bain
George "Guitar" BooksJoe-Bob "Handyman" Brown
建立一个程序，其主函数体是：
FILE *wordFile=fopen("tmp/words.txt","r");
char word[100];
while(fgets(word,100,wordFile)){
word[strlen(word)-1]='0';
NSlog(@"%s is %d characters long",word,strlen(word));
运行的结果是：
Joe-Bob "Handyman" Brown is 24 characters long
Jacksonville "Sly" Murphy is 25 characters long
Shinara Bain is 12 characters long
George "Guitar" Books is 21 characters long
===============>我的疑问是：while(fgets(word,100,wordFile))里的fget(word,100,wordFile)，作用不是直接读取全部的99个字符吗？但按照结果，原理却好像是fget函数按一行一行地读取？这是怎么解释呢？ --------------------编程问答-------------------- char * fgets ( char * str, int num, FILE * stream );
Get string from stream
Reads characters from stream and stores them as a C string into str until (num-1) characters have been read or either a newline or a the End-of-File is reached, whichever comes first.
A newline character makes fgets stop reading, but it is considered a valid character and therefore it is included in the string copied to str.
A null character is automatically appended in str after the characters read to signal the end of the C string.
Parameters
str
Pointer to an array of chars where the string read is stored.
num
Maximum number of characters to be read (including the final null-character). Usually, the length of the array passed as str is used.
stream
Pointer to a FILE object that identifies the stream where characters are read from.
To read from the standard input, stdin can be used for this parameter.
--------------------编程问答-------------------- 从流中读一行或指定个字符 --------------------编程问答-------------------- 肯定是遇到换行了吧
你需要忽略换行符
