how do I remove this
undefined reference to
error??
Thanks in advance!!

The error is saying that the linker could not find the actual function definition for those functions.
I can't see them either - where are they written?

The below are not funtions,

MsgQueue( n );
SN( n, 1 );
SE( n, n, 1 );
FI( n );

They are actually (Vectors and Containers):
vector < deque < int > > MsgQueue( int );
vector < int > SN( int, int );
matrix < int > SE( int, int, int);
vector < int > FI( int );

But compiler sees them as funtions. Could you tell me the correct way to define vectors??!!

Eureka !! Eureka !! the changes required to my first post are as follows:

Now the above code will work perfectly.
