Question

Hello guys i have a small problem at my console application
i have a text file got
19862 line

String[] lines= File.ReadAllLines("C:\\Users\\ThElitEyeS\\Desktop\\PHP\\name\\names.txt");
int c = lines.Length;
int i = 1;
foreach (String line in lines) {
    long f = ((i++ / c) * 100);
    Console.WriteLine(f + "%");
}

the value always return 0%
except the last one its return 100%
and that is my problem i hope to find question fast 🙂

Answer 1

You are making a integer devision and that will be rounded.

Example:

i = 1 and c= 100
result is 0.01  -> rounded to 0
0 * 100 = 0

Instead try

long f = ((i++ / (double) c) * 100);

to force a floating point devision.
