How is the file structured? Is it a text or binary file? Is it a flat file or a tree structure? Are the records fixed or variable length? Is there a delimiter between the ID and name? Are records in the file ordered by name or ID number?

The ans is 49 only
bcoz i cant be 2 values(6, 7) at a time so, i should be 7 at last

The usage of static with a function or variable restricts their scope.Is this behaviour memory related?

jbode

 Profile Answers by jbode Questions by jbode

• Jun 5th, 2019

The static keyword does not affect where or how a function is stored in memory. It only affects whether the function *name* is visible to code outside of the current translation unit (source file).

Harsha

• Mar 27th, 2019

You have to specify where you are going to place it. You can do this in the linker file(.lsl or .ld file). If you place it in the .text section, it goes into the Flash, else by default a static function is placed in the RAM(.data).
