C# - Logical Operators

Logical Operators in C#

Logical operators in C# are used to perform logical operations on boolean expressions. These operators return a boolean result (true or false) based on the logical relationship between the operands. The main logical operators in C# are && (logical AND), || (logical OR), and ! (logical NOT). Let's look at each of these operators in detail with examples.

1. Logical AND (&&)

Logical operators in C# are used to perform logical operations on boolean expressions. These operators return a boolean result (true or false) based on the logical relationship between the operands. The main logical operators in C# are && (logical AND), || (logical OR), and ! (logical NOT). Let's look at each of these operators in detail with examples.

bool result = expression1 && expression2;


//
bool isAdult = true;
bool hasLicense = false;
bool canDrive = isAdult && hasLicense; // canDrive is false

Explanation

In the above example, canDrive will be false because hasLicense is false, even though isAdult is true. Both conditions must be true for canDrive to be true.

2. Logical OR (||)

The logical OR operator (||) returns true if at least one of the operands is true. If both operands are false, it returns false.

bool result = expression1 || expression2;

//code
bool isWeekend = true;
bool isHoliday = false;
bool canRelax = isWeekend || isHoliday; // canRelax is true

Explanation

In the above example, canRelax will be true because isWeekend is true. For the OR operator, only one of the conditions needs to be true for the result to be true.

3. Logical NOT (!)

The logical NOT operator (!) inverts the value of the operand. If the operand is true, it returns false, and if the operand is false, it returns true.

bool result = !expression;

// code
bool isRaining = true;
bool isSunny = !isRaining; // isSunny is false

Explanation

In the above example, isSunny will be false because isRaining is true, and the NOT operator inverts the value.
