I have next code
int a,b,c;
b=1;
c=36;
a=b%c;

What does "%" operator mean?
See Question&Answers more detail:osIt is the modulo (or modulus) operator:
The modulus operator (%) computes the remainder after dividing its first operand by its second.
For example:
class Program
{
static void Main()
{
Console.WriteLine(5 % 2); // int
Console.WriteLine(-5 % 2); // int
Console.WriteLine(5.0 % 2.2); // double
Console.WriteLine(5.0m % 2.2m); // decimal
Console.WriteLine(-5.2 % 2.0); // double
}
}
Sample output:
1 -1 0.6 0.6 -1.2
Note that the result of the %
operator is equal to x – (x / y) * y
and that if y
is zero, a DivideByZeroException
is thrown.
If x
and y
are non-integer values x % y
is computed as x – n * y
, where n
is the largest possible integer that is less than or equal to x / y
(more details in the C# 4.0 Specification in section 7.8.3 Remainder operator).
