Inputting data on screen from File

[namcintosh]

First of all, here is my program:

#include <iostream>
#include <conio>
#include <fstream>              //Needed to use files
#include <iostream>
#include <fstream>
 
 
using namespace std;
 
 
int main()
{
       ifstream inFile;
       int people;
 
 
       inFile.open("people.dat");
 
       inFile >> people;
       cout << people <<endl;
 
       inFile >> people;
       cout <<people <<endl;
 
       inFile >>people;
       cout <<people <<endl;
 
       inFile >>people;
       cout <<people <<endl;
 
       inFile >>people;
       cout << people <<endl;
 
       inFile >>people;
       cout <<people <<endl; 
 
       inFile.close();
 
       getch();
       return 0;
 
}

Here is my problem:
This program should produce a bar chart showing the population growth for a small town at 20 year intervals during the past 100 years (the years are from 1900-2000). This program should read in the population figures from a file (which is people.dat). For each year, it shoudl display the date and a bar consisting of one asterdisk for each 1000 people. For example:

1900 **
1920 ****
1940 *****

Here is the data from the file.
2000
4000
5000
9000
14000
18000

I am having trouble figuring how to read the file to get it to print out a star for each 1000 years.

Does anyone have any idea how to do that?

You can divide the number in the file by 1000 and then print that many stars like this:

get number from file;
int num_of_stars = people / 1000;
for (the value of num_of_stars){
    print an asterik}
 

Hope that helps.

So, where should that code go in the program?

Before you print the number and after you read it in from the file. Then you can print out the number of stars depending on the number divided by 1000.

Can you point that out to me in my program please???

       people /= 1000;
       for (int x = 0; x < people; x++){
             cout << "*";}

}

See the bolded statements, that prints x number of stars where x is equal to the number from the file divided by 1000(one star for every 1000 in the number). Add that to the other statments after that to do that for each one. If you have more questions just ask.

Thanks so much, I got it!!! I also figured out how to put the year in beside the stars.
