Expressions and Operators

Expressions:

An expression is useful to perform a computation by using operators and operands.

In C#, we have three types of operators

· Unary operators: in this, we have only one operand.

· Binary operators: these can have two operands

· Ternary operators: it has three operands.

In c#, we have different kinds of operators

Ø Arithmetic operators:

in this type of operators, arithmetical operators are available. They are + , - , * , % , / , += , = , ++ , -- etc.by using this operators we can perform arithmetical computations like addition,substraction,multiplication,division,decrement,increment and more.

Ø Relational operators:

By using relational operators ,we can compare two expressions or values.in this we use operators like <,>,<= ,==,!=,>=

Ø Logical operatrors:

By using these operators ,we can combine two expressions into logical expressions.there three types of logical operators,they are

1. AND(&&)

2. OR (||)

3. NOT(!)

Ø Bitwise operators:

These operators evaluate the bits of a value directly

There are six logical operators

1. AND

2. OR

3. XOR

4. NOT

5. Shift left

6. Shift right

Example:

Class A

{

Static void main(string[] args)

{

int a ,b ,c ,d ,e ,f ;

a=1;

b= a + 5;

c= a + b;

c += 1;

d = a + b + c;

if (a > b)

{

e =10;

}

if (b <15 || c<5 )

{

f=3 ;

Console.writeline(f);

}

C++;

d--;

console.writeLine(c);

console.writeLine (d);

}

}
