  OPERATORS IN C Presentation By S.ShakilaBanu, MCA
• 2.
  OPERATORS The operator isa symbol that tells the computer to perform certain mathematical or logical manipulations in C operators.  C operators can be classified into number of categories.
• 3.
   Arithmetic Operators Relational Operators  Logical Operators  Assignment Operators  Increment and Decrement Operators  Conditional Operators  Bitwise Operators  Special Operators
• 5.
  Arithmetic Operators  Anoperator that performs arithmetic operation on groups and numbers. 
• 6.
   Relational Operators A relation operator checks the relation between two operands  Relational operators are used in decision making and loops
• 7.
   Logical operators Logical operators performs logical operations on give expression by joining two or more expressions or conditions .
• 9.
   Increment anddecrement operators  C allows two very useful operators increment and decrement operators.  The operator++ adds one to the operator while__ subtracts one. Both are unary operators and takes the following form. eg; pre post ++m; or m++; - -m; or m- -;
• 10.
   Conditional Operators Conditional operators also known as ternary operators.
• 11.
   Bitwise Operators Bitwise operators are the operators used to perform the operations on the data at the bit level.  When we perform the bitwise operations ,then it is also known as bit- level programming .
• 12.
   Special Operators These are used to perform mathematical calculations like addition, subtraction ,multiplication , division and modulus .  Special operators can be divided in to 2 types  THE COMMA OPERATOR  THE SIZE OPERATOR
• 13.
   THE COMMAOPERATOR  The comma operator is basically a binary operator.  Eg; value=(x=10,y=5,x+y);  THE SIZE OF OPERATOR  It determines the size of the expression or the data type specified in the number of storage units.  Eg; m=size of (sum);
