函数原型:char *fgets(char *buf, int size, FILE *fp); 参数: fp:指向要读取的文件,文件指针 size:每次能够读取size-1大小的字符 buf:读取的内容存放到buf指向的空间中去 返回值:当读取成功的时候返回读取字符的首地址,如果不成功或者读到了文件结尾(EOF)时候返回NULL 例子:......

To define fgets() in C, use the syntax here: char *fgets(char *str, int size, file* file); The char str variable stores a string or an array of fixed length after it has been read. The size parameter specifies the number of characters to read, ending with the null character. ...
