- this program retrieves data from a file (name given by the user), which contains population data from 1970 to 2022 for each country (file name: World Population.txt)
- the program performs calculations on data (such as the percentage change in population between 1970 and 2022 for each continent, the share of each continent's population in the world's population (%), etc.)
- the program creates an Excel file (name given by the user) and charts in it on the basis of data from calculations
- the program creates a file (name and type of file given by the user) and saves data from calculations in it
For creating charts in Excel you need to download the NuGet toolkit "EPPlus"
In the process of creating this program, I trained my skills of working with files, exception handling and I learned how to create Excel files using EPPlus
