**What it does**

This program implements arithmetic operations on tabular files data. The program takes three inputs:

- The first input is a TABULAR format file containing numbers only.
- The second input is a TABULAR format file containing numbers only.
- The third input is an arithmetic operation: +, -, x, or / for addition, subtraction, multiplication, or division, respectively. 
- The output file is a TABULAR format file containing the result of implementing the arithmetic operation on both input files.


Notes: 

- The two files must have the same number of columns and the same number of rows.
- The output file has the same number of columns and the same number of rows as each of the two input files.
- In case of division, none of the values in the second input file could be 0, otherwise the program will stop and report an error.

**Example**

Let us have the first input file as follows::

        5       4       0
        10      11      12
        1       3       1
        1       2       1
        2       0       4
        
And the second input file as follows::

        5       4       4
        2       5       8
        1       2       1
        3       2       5
        2       4       4

Running the program and choosing "Addition" as an arithmetic operation will give the following output::

        10      8       4
        12      16      20
        2       5       2
        4       4       6
        4       4       8
