Do your own homework.

An abstract data type is like a normal data type, say int or char, but
one that was originally only intended to compile on Abstract C, an
implementation of C by K&R that built upon the C89 standard, and added
support for ADTs and abstract constants (off-topic, quite an advanced
subject).
Many other languages have added implementations of this feature, which
is why for example you'll hear of Java developers and C++ developers
talking of ADTs.
Two examples of ADTs are:
1. abs_int - an abstract definition of the integer type, which can also
store dates in native system format, and floating point values of up to
20 significant digits.
2. linked lists - these are abstract data types that have been
implemented in almost every modern language. Note that they originated
in Abstract C (a sore point with Abstract C developers), and were
rapidly adopted by other languages.
Hope that answers your question in an appropriate fashion.

I bet the OP hands in your answer to his instructor, word-for-word.
