Operator
  • An operator is a symbol or a special character that tells the computer to perform certain mathematical or logical manipulations which is applied to operands to give a result.
  • It can operate on integer and real numbers.
Usage
  • Operators are used in programs to manipulate data and variables. They usually form a part of mathematical or logical expressions.

operands
  •     The data items that operators act upon to evaluate expressions are called as operands.
  •     Most operators require two or more operands while others act upon a single operand.
  •     Most operators allow the individual operands to be expressions.
  •     A few operators permit only single variables as operands.
  •     The operands can be integer quantities, floating-point quantities or characters

Various types of Operators

C supports a rich set of operators. C operators can classified as
  • Arithmetic Operators
  • Relational Operators
  • Logical Operators
  • Assignment Operators
  • Arithmetic assignment Operators
  • Increment and Decrement Operators
  • Conditional Operator
  • Bitwise Operators
  • Special Operators
