## There are totally 3 scripts in the document
## Each of them displays different features from others.
#
# 1solution.cpp
## Reads a csv file and displays a Restaurant Menu. Then asks users what to order in a numeric way.
## Once the person selects all the items, the program will split the amount by number of customers.
## This program also takes multiple orders and calculates all the order total once the program ends.
## To run this file, use following command:## Compile first,
## --> g++ 1solution.cp
## --> ./a.out
#
# 2file.cpp
## In this script user can input the values asked in the field. Once everything are answered, then they will be stored in txt file.
## To run this file, use following command:
## Compile first,
## --> g++ 2file.cp
## --> ./a.out
#
# 3image.cpp
## Open and displays an image using opencv library.
# Here I will provide instructions to install opencv in ubuntu 18.04
