/ *将此文件另存为foo.c * /
#include< stdio.h>
int main（无效）
{
FILE * fp = fopen（" foo.c"，" r"）;
if（fp！= NULL）
{
int ch;
while（（ch = getc（fp））！= EOF）
{
putchar（ch）;
}
fclose（fp）;
}
返回0;
}
或者，查看quine在网上。

/* save this file as foo.c */
#include <stdio.h>
int main(void)
{
FILE *fp = fopen("foo.c", "r");
if(fp != NULL)
{
int ch;
while((ch = getc(fp)) != EOF)
{
putchar(ch);
}
fclose(fp);
}
return 0;
}
Alternatively, look up "quine" on the Web.

----- -------------------------------------------------- --------------------------
用
FILE * fp替换上面一行= fopen（__ FILE __，" r"）;
------------------------------- -------------------------------------------------- if（fp！= NULL）
{
int ch;
while（（ch = getc（fp））！= EOF）
{
putchar（ch） ;

replace the above line with
FILE *fp = fopen(__FILE__,"r");
--------------------------------------------------------------------------------- if(fp != NULL)
{
int ch;
while((ch = getc(fp)) != EOF)
{
putchar(ch);

fclose(fp);
