|        Please consider the following C programme -
| 
|       1  #include <stdio.h>
|       2
|       3  void abc();
|       4  main()
|       5  {
|       6    abc();
|       7    abc();
|       8  }
|       9
|      10  void abc()
|      11  {
|      12     char *p = "raman";
|      13     printf("%s\n",p);
|      14     strcpy(p, "shyam");
|      15  }
| 
|       The O/P of the program is -
|        raman
|        shyam

An equally likely outcome is:

    raman
    Bus error (core dumped)

|      Though one would expect that the word 'raman' will be printed twice.

One would have no expectations at all -- the program is
incorrect and its behaviour is explicitly undefined by the
standard.

You cannot write to a string literal.

|      I think that the O/P obtained is related to the fact that string
|      literals are stored in data segment.

The reasons for the output are of little interest.  Your code is
wrong and it can do anything at all.
