Operators and Expressions
Operators are those symbols that perform some specific task. Like, when we add two numbers we generally use '+' sign. In programming also, to perform some specific task, compiler has assigned some specific symbols. These symbols are called operators.
The data items that operators act upon are called operands. Some operators require one operand to act upon, whereas some require more than one.
An expression is a combination of operands and operators written according to the syntax of language.

Since some operators require one operand, whereas some require more than one. Depending upon the number of operands required by the operators, we can broadly divide operators into three distinct categories.
