Question

Write a c++ program to load two column of numbers, do arithmetic operations to the data points by following the steps below carefully. Output the computed results to the specified output files

Steps to complete.

0. Download the data file named Datafile1.data from the file area of the assignment.

1. Load two columns of data points, each column into a storage area, preferably a vector.

2. Add each position of the data and store it in another storage area.

3. Multiply each position of the data and store it to another storage area.

4. Write the results of addition and multiplication to file named Output-Multiplication.data and Output-Addition.data

Datafile1.data
