A simple query about memory mgmt

[Santosh Pradhan]

Hi All,
I am new to this group and I have a question regarding following C program.

#include<stdio.h>

#define NAME "santosh"

int main()
{
    char *p_name = NAME;
    char *q_name = NAME;
    if (p_name == q_name)
         printf("Hello, World\n");
    return 0;
}

When I compile this test program, it always prints "Hello, World".

My Question:

i) Does compiler do any optimization automatically to make both the pointers
have same address ?

ii) How does this happen?

iii) Will both the pointers be same always?

iv) Will it differ in other platforms like prop. Unix (AIX/HP-UX etc.) and
Win?

Any kind of help is appreciated.

Sorry, if it is not the right place to ask this :(.

Thanks in advance.

Regards,
Santosh
