How to use remainder operator
Description
In C# we can use % operator to get remainder.
Example
Example for C# Remainder operator
using System; /* w w w.ja va 2 s . c o m*/
class Example {
public static void Main() {
int iresult, irem;
double dresult, drem;
iresult = 10 / 3;
irem = 10 % 3;
dresult = 10.0 / 3.0;
drem = 10.0 % 3.0;
Console.WriteLine("Result and remainder of 10 / 3: " +
iresult + " " + irem);
Console.WriteLine("Result and remainder of 10.0 / 3.0: " +
dresult + " " + drem);
}
}
The code above generates the following result.
Determine smallest single-digit factor
How to use remainder operator to determine smallest single-digit factor
//from w w w . j ava 2s. c om
using System;
class MainClass {
public static void Main() {
int num;
for(num = 2; num < 12; num++) {
if((num % 2) == 0)
Console.WriteLine("Smallest factor of " + num + " is 2.");
else if((num % 3) == 0)
Console.WriteLine("Smallest factor of " + num + " is 3.");
else if((num % 5) == 0)
Console.WriteLine("Smallest factor of " + num + " is 5.");
else if((num % 7) == 0)
Console.WriteLine("Smallest factor of " + num + " is 7.");
else
Console.WriteLine(num + " is not divisible by 2, 3, 5, or 7.");
}
}
}
The code above generates the following result.
