adding 48 to string number

Question

I have a string in C# like this:

string only_number;

I assigned it a value = 40

When I check only_number[0], I get 52
When I check only_number[1], I get 48

why it is adding 48 to a character at current position? Please suggest

Answer 1

String is basically char[]. So what you are seeing is ASCII value of char 4 and 0.

Proof: Diff between 4 and 0 = Diff between 52 and 48.

Since it is a string so you didn't assigned it 40. Instead you assigned it "40".
