C++ Operators
C++ operators are symbols that are used in the C++ program to form an expression.C++ has a large set of operators. It includes all C languages operator and has its own other operators. There are three categories of an operator in C++. They are listed below:
- Unary Operators
- Binary Operators
- Ternary Operators
Unary Operators
Unary operators are those operators that operate a single operand to form an expression. There are basically two unary operators.
- +(increment) operator
- -(decrement) operator
Binary Operators
Binary operators are those operators that operate two or more operands to form an expression. Some of the binary operators are -,+,/,*,! etc.
Example: x+y,x*y,x-y,x/y etc.
Ternary Operators
Ternary operators are those operators that operate a minimum of three operands. There is a single ternary operator that is available in C++. The only available ternary operator in C++ is ? that is used as a substitute for an if-else statement.
Example: x>y ? x:y
Types of Operators in C++
- Arithmetic operators
- Logical operators
- Comparison operators
- Assignment operators
- Bitwise operators
- Comma operators
- Increment and Decrement operators
Arithmetic operators
The operators that help the programmer in a mathematical calculation is known as arithmetic operators.
| Operators | Used For |
| + | Addition |
| – | Subtraction |
| * | Multiplication |
| / | Division |
| % | Modulus |
Example:5+8,4*2 etc.
Logical operators
The operators that help the programmer to connect two or more expression is known as logical operators.
| Operator | Used For |
| && | Logical AND |
| || | Logical OR |
| ! | Logical NOT |
Comparison operators
Comparison operators are those operators that are used to compare variables. It returns the value either true or false. They are also known as relational operators.
| Operator | Used For |
| > | Greater than |
| Less than | |
| = | Is equal to |
| != | Is not equal to |
| >= | Greater than or equal to |
| Less than or equal to |
Assignment operators
Assignment operators are those operators that are used to assign values to the identifier. The assignment operator used in C++ is a “=” operator.
Example: x=5; (assigns the value 5 to x)
Bitwise operators
Bitwise operators are those operators that operate at a bit level and allows the programmer to manipulate individual bits. They are basically used for testing or shifting bits.
| Operators | Used For |
| Binary Left Shift Operator | |
| >> | Binary Right Shift Operator |
| & | Binary AND Operator |
| ^ | Binary XOR Operator |
| | | Binary OR Operator |
| ~ | Binary One’s Complement Operator |
Comma Operators
Comma operators in C++ are used to separate variable names or expression.
Example:int x,y,z;
Increment and Decrement Operators
Increment and Decrement operators in C++ are used to increase and decrease the values of the operand respectively.
| Operators | Used For |
| + | Increment |
| – | Decrement |
