Операторы

Operators in C++ are used to perform operations on variables and values. They are mainly divided into four categories: arithmetic, assignment, relational, and logical.

Arithmetic Operators

These are used to perform common mathematical operations:

Assignment Operators

Used to assign values to variables. C++ also supports compound assignment operators:

int x = 10;
x += 5; // Equivalent to x = x + 5 (15)
x *= 2; // Equivalent to x = x * 2 (30)

Relational Operators (Comparison)

These return a boolean value (true or false):

• == Equal to
• != Not equal to
• > Greater than
• < Less than
• >= Greater than or equal to
• <= Less than or equal to

bool result = (10 > 5); // true

Logical Operators

Used to combine multiple boolean expressions:

• && Logical AND: true if both expressions are true.
• || Logical OR: true if at least one expression is true.
• ! Logical NOT: reverses the truth value.

bool isAdult = true;
bool hasTicket = false;
bool canEnter = isAdult && hasTicket; // false
