Can someone explain to me how come the output of the code below is 4?

Question

string s = "SoloLearn";
int x = s.Length;
int y = s.IndexOf("e");
Console.Write(x%y);

Answer 1

9 mod 5
So, The ans will be 4

Answer 2

"SoloLearn" is long 9
C# starts to count from 0 , so "S" is in "0" position the "e" is in fifth position

9 mod 5 = 4

and if you don't know what "modulo operation" is : https://en.wikipedia.org/wiki/Modulo_operation

Answer 3

i think, here important thing is, for .Length method starts with 1 , but index of array starts with 0.

Answer 4

im still alil confused can you please explain it over alil slower and whats the meaning of MOD @Sam

Answer 5

Here:
x = 9
y = 5 ( cause "e" is the 5th index from 0, aka "S"
So when x%y is actually saying "what is the remainder from 9 devided by 5, which is 4 because 9/4 is 1 with a remainder of 4, aka 1.4.
I hope that helped.
