The red is a cast expression, and is unnecessary.

So use a counter.

@yellowSnow
And if fgets() returns NULL because of an error (and not because of end of file), then what?

Don't use feof() to control a loop (http://faq.cprogramming.com/cgi-bin/smartfaq.cgi?answer=1046476070&id=1043284351)

Use
while ( fgets(buffer,sizeof(buffer),myfile) != NULL )

Well to be pedantic again, you should have written
const char *p="abc";
then the compiler itself would have complained about the attempt to modify a constant.

Because so much existing code...

> char *p = &q;
Did you try it?

&q has a different type to q, so any good compiler would complain about incompatible pointer assignments.

The first ++ tried to modify what p points to.
Since p points to a string constant, your program dies because it tried to modify something in read-only memory.

Only that strdup() isn't a portable function.

I see the OP got their wish by successive approximation without having to put in any more effort.
