We've been through this before:

Again, this is a basic principle of the 'C' programming language - you really need to get this thoroughly understood before moving on!

Otherwise it's just going to keep coming back to bite you again - like this!

i have declared everything and also added the c files and h files 

even though it showing error that's why i raised the question

Clearly you haven't - that's why you get the error!

Most likely, the declaration you have is not visible at the point where the error is reported.
