It is unspecified whether or not the compiler will allocate one or two
copies of the character sequence "santosh" and therefore whether or not
p_name != q_name;

Refer to below link ...... first bullet clearly says that gcc will
store only one copy if strings are identical.

http://gcc.gnu.org/onlinedocs/gcc-3.4.6/gcc/Incompatibilities.html

It clearly says that gcc version 3.4.6 will do so. And it makes perfect 

sense to do so ofcourse but as far as C the language is concerned, it's 

unspecified and I can assure you that I've used compilers that did not.

(whether or not I was happy to be using those compilers is secondary)
