Hi;
I wrote a program that I want to put a number in char (I mean : char
s = '8';)
7 than put the number I put that at char s to int ;
But it does not work correctly ;
I mean it doesn’t show 8 ;
using System;
class Program
{
static void Main(string[] args)
{
char s = '8';
int f =s;
Console.WriteLine(f);
}
}

thanks . . .

All writeable characters has a specific representation in ASCII for example
the chracter '8' is represented by
number 56. When you do
int f =s;
you say tell me what number character '8' represents and you will have
number 56

What makes you think that it should show 8?
Time to learn the difference between char and int.

this : y=(x^2)+1 so i will put 2 in char but to write the program for
it that it must do an math question ,program must know that 2 & 1 are

You already got answers that told you a little about the different types.
Maybe you simply read more about ascii and UTF(-8/-16/-32). Good sources can
be found through google or simply check the wikipedia.

The .Net Framework provides functions to get information from one type to
another. In case of reading stings (Which are multiple characters), the
functions you would like are:
Int32.Parse and Int32.TryParse.

Just check msdn for a description of these functions (and msdn often has an
example that shows the possibilities in a quick way!).
