WRITE IT IN C$++$

Update the program in the previous Task to include the following two derived classes:

FibonacciSeq that overrides the function sequenceTerm to return the terms of the Fibonacci sequence: $1,1,2,3,5,8,13,21,34,...$

TriangularSeq that overrides the function sequenceTerm to return the terms of the triangular sequence: $1,3,6,10,15,21,28,$dots

The following figure illustrates how the numbers of the triangular sequence can be generated.

The following program defines a main function that can be used to test the FibonacciSeq and TriangularSeq classes.

The following is an example snapshot of the above program's input and output.
