What exactly do you need help with? the file operations? What will be the contents of the file?

i have a separate input file, which has number of population. it means that this progrm doesnt require user input. i need the algorithm at the part where it will read the population n then prints the asterisks....

let say if 2000 population it will print **, if 3000 it prints *** and so on

To read the values in from the file I would use <fstream>. To decide on the amount of asterisks to show for each value will be based on the range of values that are present. Were you given the range of values that you could possibly see? Also will the values be numbers be easy to deal with like "2000" and "3000" or could you possibly see values like 2005 and 3002? More information would be nice, thanks.
