As far as I know, they're just two different ways of saying the same
thing.

Please use proper capitalization, and avoid abbreviations like "u" for
"you"; they make your text more difficult to read.

We must do something. This is something. Therefore, we must do this.

function pointer means function returning pointer.
1)int * add(int x,int y)
{
int z;
z = x+y;
return(&z);
}
we may put a function call as follows
int *a;
a = add(x,y);

2)pointer to a function is a function whic in turn points to another
function.
like
int add();
int (*addi)();
addi =&add;
then (*addi)() represents add();

this is the difference b'wn function pointer and pointer to a function.

No, it doesn't.

No, it isn't.

No, it isn't.

A pointer to a function is a pointer that points to a function. A function
pointer is a pointer that either has an indeterminate value, or has a null
pointer value, or points to a function.

No, when people say function pointer they normally mean a pointer to a
function. At least, that has been the case every time I've seen the term
used (and I've both seen and used it a fair bit) it has meant a pointer
to a function.
1)int * add(int x,int y)
This I ouw call a function returning a pointer to in, or if I'm not
bothered about the type a function returning a pointer.
{
int z;
z = x+y;
return(&z);
}
we may put a function call as follows
int *a;
a = add(x,y);

int (*addi)();
addi =&add;
You don't need the & although it does no harm.
then (*addi)() represents add();

this is the difference b'wn function pointer and pointer to a function.

Maybe the way you use the terms, but that is not what I've come across
in far too many years of programming in many languages.

They're just two different ways of describing the same thing as far as
I know.

He, he, when I read kishore's response, I swear there was a line saying
<enable twisted homework response mode>. Maybe that didn't come though
on your copy. ;-)
