How to make a vector structure globaly ?

[rajeevkag]

We are developing a C++ project with 10 cpp files and 3 header files.We are declared array structure of 3 integer varibles globaly in header file and using in some files and where arrays are updated ,re-adjusted in some cpp files and use in another files.Project is running fine but we wish to use vector structure because dynamic allocation and easy resize.
