另类比较字符串的算法(转载)

char p[]  =   " HTTP " ;
       
         if ( * (unsigned long  * )p  !=   * (unsigned long  * ) " HTTP " )
        {
             printf ( " error!\n " );
        }
         else
        {
                 printf ( " right!\n " );
        }

 

只适合固定字符串的长度..如果字符串长度超过usigned long 的字节数就不行了.
不过很高效的
