本程序中，函数fun的功能是判断字符串是否是回文，若是回文，则返回1，主函数中输出YES；否则，函数返回0，主函数中输出NO。回文是指顺读和倒读都一样的字符串。例如，字符串LEVEL是回文，而123312就不是回文。请在函数fun的花括号中填入你编写的若干语句。（注意：不改动程序的结构，不得增行或删行。）
#include
#define N 80
int fun (char *str)
{
}
main()
{ char s[N];
printf(“Enter a string : ”) ;
gets (s) ;
printf(“\n\n”) ;
puts (s) ;
if (fun (s))
printf (“YES\n”) ;
else
printf (“N0\n”) ;
nono ();
}
nono ()
{/*请在此函数内打开文件,输入测试数据,调用fun函数,输出数据,关闭文件.*/

wf = fopen (“bc.out”,“w”) ;
for (i=0; i<10; i++ )
{ fscanf (rf, “%s”,s ) ;
if (fun (s ))
