Unit 3: Object-Oriented Programming in C++

3.4.2 UNARY, BINARY AND TERNARY OPERATORS

There are three types of operators in C++ which are unary, binary, and ternary operators.

The operator that works on a single operand is known as a unary operator. Unary operators are -, ++, --, and the logical operator !.

Some examples of unary operators are
a= -b;
k++;
--X;
The operators that work on two operands are known as binary operators. Binary operators are - ,+,,/, %, and logical operators && and II.

Some examples of binary operators are
a=b+c;
z=xy;
k=d%e;

The conditional operator (?;) is known as a ternary operator since it has three parts. These three parts are a condition and two expressions. The condition is evaluated and based on its result one of the two expressions is executed.
