1.Design environment
Start a subscription from Visual Studio 2012 or Visual Studio2010. Go to the File
menu and choose New Project
(Visual Studio2010)
This window will also allow you to change the name of the program and

3.Character constants
Character literals are included in single quotes. For example, 'x' can be
stored in a simple variable of char type. A literal character can be a
regular character (such as 'x'), an escape sequence (such as ' t'), or a
generic character (such as ' u02C0'). There are some characters in C #
when preceded by a backslash. They have a special meaning and are
used to represent such as the new font ( n) or the tab ( t). The
following is a list of some of these escape sequence codes:
Escape sequence Meaning
character
' ' character
" " character
? ? character
a Alert or bell
b Backspace
f Form feed
n Newline
r Carriage return
t Horizontal tab

4.Arithmetic Operators
Following table shows all the arithmetic operators supported by C#.
Assume variable A holds 10 and variable B holds 20 then:
Operator Description Example
+ Adds two operands A + B = 30
- Subtracts second operand from the first A - B = -10
* Multiplies both operands A * B = 200
/ Divides numerator by de-numerator B / A = 2
% Modulus Operator and remainder of after an integer
division
B % A = 0
++ Increment operator increases integer value by one A++ = 11
-- Decrement operator decreases integer value by one A-- = 9
Table 0-1 Arithmetic Operators
Example
x = int.Parse(textBox1.Text);
y = int.Parse(textBox2.Text);
r = x * y;
textBox3.Text = r.ToString();
