一道C语言题目 void func(char *s1,char *s2)/*s1为字符串的起始地址s2为新字符串的起始地

void func(char *s1,char *s2){int i = 0 ,k = 0,count = 0 ,temp = 0 ;while( '\0' != * ( s1 + i ) ){*( s2 + i ) = * ( s1 + i ) ;i ++ ;}count = i ;for( i = count - 2 ; i >=0 ; i -- ){for( k = i - 1 ; k >= 1 ; k -- ){if( s2[ k ] < s2[ i ] ){temp = s2[ k ] ;s2[ k ] = s2[ i ] ;s2[ i ] = temp ;}} }}
