C# Tutorial: 03 - C# Operators

Tutorial 03: C# Operators

Like all programming languages, C# also have operators. Operators are basically symbols which are used along with operands  as follows:

• Arithmetic (+, -, *, /, %, ++, --)
  
• Relational (<, >, <=, >=, !=, ==)
  
• Logical (&&, ||, !)
  
• Bit-wise (<<, >>, |, &, ^, ~)

Arithmetic Operators

These are used for performing arithmetic operations. Create a new Console Application and use following example:

After execution you will see following Output on screen:

Relational Operators:

These operators are used for comparing operands which are being used with them. They return either true or false based on their comparison. See following

Logical Operators:
Logical operators allows a program or part of program to make decision. The multiple conditions which are being used, concludes to a decision. Each operand evaluates to either true or false based on its condition. The values of operands are then used to evaluate the complete expression.

Bit-wise Operators:

& (bit-wise AND)

Two numbers are required as operands and AND is performed on each bit of 02 numbers. AND generates 1 if both bits are 1.

| (bit-wise OR)

Two numbers are required as operands and OR is performed on each bit of 02 numbers. OR generates 1 if any of the 2 bits are 1.

^ (bit-wise XOR)

Two numbers are required as operands and XOR is performed on each bit of 02 numbers. XOR generates 1 if 2 bits are different.

 << (bit-wise left shift)

Two numbers are required as operands, then left shifts the bits of the first operand, the second operand decides the number of places to shift.

>> (bit-wise right shift)

Two numbers are required as operands, right shifts the bits of the first operand, the second operand decides the number of places to shift.

 ~ (bit-wise NOT)

It takes a number and all of its bits are inverted.

See the following program and execute it in your IDE by creating a Console Application. Output is mentioned in comments

In next lesson we will discuss conditional statements in C#. If you have any questions feel free to ask in comments.
