In short: They are typically called Operators and Punctuators in C family languages.
First, it make sense to identify what is operation ? ByThe definition itof operation is defined as:
An operation is an action performed on one or more values either to modify the value held by one or both of the variables, or to produce a new value by combining existing values. Therefore, an operation is performed using at least one symbol and at least one value. The symbol used in an operation is called an operator. A value involved in an operation is called an operand.
Thus, there are 3 operators and one punctuator in most C family languages:
- Unary operators
- Binary operators
- Ternary operators
- Punctuators
- Operators and Operands in C#
