search vectors

[C++ Programming]

Hi guys,

I have two vectors of string
and I'm looking for an easy way to find the first vector sequence or sub-sequence into the first one

for example:

Vect_1 < "JAVA", "ADA", "C", "C++", "C#">
Vect_2 < "C++", "C#">

search vect_2 sequence in vect_1 will return vect_1 position 3 and match length 2

Vect_1 < "JAVA", "ADA", "C", "C++", "C#">
Vect_2 < "JAVA", "C#">

search vect_2 sequence in vect_1 will return vect_1 position 0 and match length 1

thanks for any idea, suggestion
