[Insight-users] Difference between .cxx and .cpp, .txx and .h

[jiafucang]

Hello Chunyan,

cxx and cpp files do not have difference, they both are C++ implementation 
files. It is very common that Visual C++ use cpp often, while some Unix 
programs like cxx often. Txx files is the template files, which could not be 
compiled directly, and have to be instantized. For example, the libraries in 
the ITK is very small because most of them are templates. The .h files are 
header files, such as the class definition. And the implementation will be 
placed in .cxx or .cpp files in common.

HTH,
Fucang

Hi, all,
I want to know that what is the difference between file .cxx and .cpp, and 
same question to file .txx and .h?

I found many examples in itk use these extensions.

Could some one explain me?

Thanks a lot!

Chunyan
