strlen函數實現的幾種方法

  strlen(  *p)；

 #include  
 #include <stdio.h>
 #include <.h>
 #include <assert.h>
 
  myStrlen(  *  myStrlen1(  *  myStrlen2(  *  
        *str=     str =      printf(     printf(     printf(     printf(  
  myStrlen(  *str)   
       ( (str == NULL) || (*str ==                          myStrlen(str+)+   
  myStrlen1(  *str)  
      assert(str !=       *str ? (myStrlen1(++str) + ) :    
  myStrlen2(  *str)  
       (str==NULL)         len =       (; *str++ !=            len++       }
