C# - Boolean Expression

Boolean Expression in C#

Relational operators compare two values and return a boolean result.

1.Equality (==):

int a = 5;
int b = 10;
bool isEqual = (a == b); // false

2. Inequality (!=):

bool isNotEqual = (a != b); // true

3.Greater Than (>):

bool isGreater = (a > b); // false

4.Less Than (<):

bool isLess = (a < b); // true

5. Greater Than or Equal To (>=):

bool isGreaterOrEqual = (a >= b); // false

6. Less Than or Equal To (<=):

bool isLessOrEqual = (a <= b); // true

Boolean Expressions with Logical Operators

 Logical operators combine multiple boolean expressions.

1 .AND (&&):

bool result = (a > 0 && b > 0); // true if both a and b are greater than 0

2. OR (||):

bool result = (a > 0 || b > 0); // true if either a or b is greater than 0

3. NOT (!):

bool isNotTrue = !(a > b); // true because a is not greater than b

4. XOR (^):

bool result = (a > 0 ^ b > 0); // true if only one of a or b is greater than 0

Combining Boolean Expressions

You can combine multiple boolean expressions to create complex conditions.

bool isAdult = (age >= 18);
bool hasPermission = true;
bool canEnter = isAdult && hasPermission; // true if both isAdult and hasPermission are true

Boolean Expressions in Conditional Statements

Boolean expressions are often used in conditional statements like if, else if, and while.

if (isAdult && hasPermission)
{
    Console.WriteLine("You can enter.");
}
else
{
    Console.WriteLine("You cannot enter.");
}

Boolean Expressions in Loops

Boolean expressions control the execution of loops.

int count = 0;
while (count < 10)
{
    Console.WriteLine(count);
    count++;
}
