This function will readall the data until the end of file, perform the density calculation for each country andsave the results in an ouput file. This is a void function. The output file should list the names of the countries aligned to the left, and thecountries population densities aligned to the right and with two decimal places. Hereis a sample of what the first few lines of a typical output file would look like:Do not forget to: Close the files once you are done using them  Have a comment on top of the function prototype explaining the function’s purpose,parameters, etc.
