.. class:: infomark **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
