C++ Operators

• Operator in C++ is a symbol or keyword used to perform operations on operands.
• Operands can be variables, constants, or expressions, and operators dictate how these operands are combined.

Operators in C++

• Arithmetic Operators
• Relational Operators
• Logical Operators
• Bitwise Operators
• Assignment Operators
• Unary Operators
• Ternary or Conditional Operators
• Miscellaneous Operators

Arithmetic Operators

• Addition (+): Adds two values together.
• Subtraction (-): Subtracts one value from another.
• Multiplication (*): Multiplies two values.
• Division (/): Divides one value by another.
• Modulus (%): Returns the remainder of a division operation.

Relational Operators

• Relational operators are used to comparing values and determine the relationship between them.
• These operators return either true or false. Common relational operators include:
• Equal to (==): Checks if two values are equal.
• Not equal to (!=): Checks if two values are not equal.
• Greater than (>): Checks if one value is greater than another.
• Less than (<): Check if one value is less than another.
• Greater than or equal to (>=): Checks if one value is greater than or equal to another.
• Less than or equal to (<=): Checks if one value is less than or equal to another.

Logical Operators

• Logical operators are used to perform logical operations on Boolean values.
• They are often used in conditional statements and loops. The common logical operators are:
• Logical AND (&&): Returns true if both operands are true.
• Logical OR (||): Returns true if at least one operand is true.
• Logical NOT (!): Returns the opposite of the operand's value.

• Operand 1: a (with a value of 10)
• Operand 2: b (with a value of 0)
• Result: The logical AND operator (&&) evaluates to true (1) if both operands are true (non-zero). In this case, a && b evaluates to 0 (false) because b is 0, which is considered false.

• Operand 1: a (with a value of 10)
• Operand 2: b (with a value of 0)
• Result: The logical OR operator (||) evaluates to true (1) if at least one operand is true (non-zero). In this case, a || b evaluates to 1 (true) because a is 10, which is considered true.

• Operand A: a (with a value of 10)
• Operand B: b (with a value of 0)
• Result (a): The logical NOT operator (!) negates the value of the operand. In this case, !a evaluates to 0 (false) because a is initially true (non-zero), and the NOT operator flips it to false (0).
• Result (b): Similarly, !b evaluates to 1 (true) because b is initially false (0), and the NOT operator flips it to true (1).

• a && b evaluates to 0 (false) because both operands are not true.
• a || b evaluates to 1 (true) because at least one operand is true.
• !a flips the value of a from true to false.
• !b flips the value of b from false to true.

Bitwise Operators

• Bitwise operators work at the bit level and are used to manipulate individual bits within data.
• They are especially useful when dealing with hardware or low-level operations. Common bitwise operators include:
• Bitwise AND (&): Performs a bitwise AND operation.
• Bitwise OR (|): Performs a bitwise OR operation.
• Bitwise XOR (^): Performs a bitwise XOR (exclusive OR) operation.

Assignment Operators

Unary Operators

• Unary operators operate on a single operand.
• An example is the unary minus (-) operator, which negates a value.

Ternary or Conditional Operators

• The ternary operator (? :) is a concise way to write conditional statements.
• It evaluates a condition and returns one of two values based on whether the condition is true or false.

Miscellaneous Operators

• There are several other operators in C++, such as the address-of operator (&) and the pointer dereference operator (*), which are often used in more advanced programming scenarios.
• However, for beginners, understanding the operators mentioned above is a great starting point.
