Eclipse C Engineering header file introduces __ide

We are in the development of C + +, used to put the head file a folder such as include, source files put Src, so that in the source file include your own header file can not find the end file,
This is because Eclipse does not add its own folder path within the same project, so its own header file is in front of you, but is not found, the solution:

Point C + + project right, Properties-> C/R + + General-> Paths and Symbol-> includes tags under Add, add your project include folder to find the header file.
