Can y'all please just listen to Johannes? It definitely does. We have:
int main()
{
char *p_name = "santosh";
char *q_name = "santosh";
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;
Just replace it by
int main()
{
char *p_name = "santosh";
char *q_name = "peter";
to understand that allocating it just once is an optimization.
