一,fgets函数的使用
char *fgets(char *s, int size, FILE *stream);
说明:
fgets() reads in at most one less than size characters from
stream and stores them into the buffer pointed to by s.
Reading stops after an EOF or a newline. If a newline is
read, it is stored into the buffer. A terminating null byte
('\0') is stored after the last character in the buffer.
fgets函数是以\n\0结束的 使用在使用的要注意
