Operators in C

Every C program is developed using five fundamental units keywords, identifiers, operators, separators and literals. In previous post, we already learned about Keywords and identifiers. Here in this post we will focus on operators.

Operators: Operator is a symbol given to an operation that operates on some value. It tells the computer to perform some mathematical or logical manipulations. Such as + is an arithmetic operator used to add two integers or real types.

C language provides a rich set of operators. Operators are classified into following categories based on their usage.

1) Increment/Decrement | Unary Operators

2) Arithmetic Operators

3) Bitwise Operators

4) Relational Operators

5) Logical Operators

6) Conditional or Ternary Operators

7) Assignment Operators

8) Other Operators

1) Increment/Decrement | Unary Operators:

Increment/decrement operator is also known as unary operator. Unary operators, menaning operate on a singal operand. The increment operator (++) is used to increase by 1 to its operand and the decrement operator decrease by one 1 to its operand.  

Increment/decrement operators are of two types prefix and postfix. Let's suppose a = 10 and b = 5 is.
++	Increment operator will add 1 to its operand.	a++ will result to 11 ++a will result to 11
--	Decrement operator will subtract 1 from an integer value.	a-- will result to 9 --a will result to 9
