NULL Pointer Bugs

NULL Pointer Bugs

A NULL character pointer isNOTthe same as a pointer to a NULL string. In Solaris, the following program will lead to a "Segmentation Fault".

1. #include<stdio.h>
2. #include<string.h>
4. intmain()
5. {
6. char*string=NULL;
8. printf("/nStringlength=%d",strlen(string));
10. return0;
11. }

I don't know hwy this happens clearly now, and it should be pay more attention.
