NULL pointer assignment error- AGNEL ANTO

What is NULL pointer assignment error ? My program comes up with the message 'Null pointer assignment' after it terminates. What does this mean? Before a small-data model Turbo C program returns to DOS, it will check to see if the beginning of its data segment has been corrupted. This message is to warn you that you have used uninitialized pointers or that your program has corrupted memory in some other way.
