If I write char * p = "Welcome". I can see the address for p. But what's the address for the string i.e at which address Welcome stored?
If I write again char *s = "Welcome". p and s will point to same address?

In a debugger, if you inspect p, you will see the address of the string.
&p is the address of p itself.
And no, p and s are not guaranteed to point to the same address, but they might.

Indeed. Some compilers recycle string constants, so the addresses may be the same. – Ben Ruijl Sep 14 '12 at 11:56

"Welcome" is string constant and it is stored in read only data section of memory but pointer p is created in stack which points to this string literal

The question does not imply anyhow that p is a local variable. It can be in the data section as well (writable) and not on the stack. – Alexey Frunze Sep 14 '12 at 12:02

Thanks..How to print the address of this const string? *p gives the the string value and &p gives p address.Sorry to bother you guys. Printing *p with %s gives string and %x giving the address. Hope what comes on print with %x is the address of constant string. – Ramana Sep 14 '12 at 12:22

String constant "Welcome" often are putted in "read-only-data" section of memory. Here are good explanations about: String litereals where do they go and data segment
you can find the address of string constant "Welcome" by
printf("%p",p);
If I write again char *s = "Welcome". p and s will point to same address?
Maybe same string constant are putted in the same address, maybe not.
