这是《Keil Cx51 V7.0单片机高级语言编程与uVision2应用实践》教材各章中列出的全部程序例子。

    #include <stdio.h>
    main()  {
       char *s = "abcdef";
       int  strlen(char *s);
       printf("\n length of '%s' = %d\n",s,strlen(s));
       while(1);
     }

    int strlen(char *s)  {
       char *p = s;
       while( *p != '\0' ) p++;
       return( p - s );
