C Operators And Expressions


Operators In C
  • The symbols which are used to perform logical and mathematical operations in a C program are called C operators.
  • These C operators join individual constants and variables to form expressions.
  • Operators, functions, constants and variables are combined together to form expressions.
  • Consider the expression A + B * 5. where, +, * are operators, A, B are variables, 5 is constant and A + B * 5 is an expression.

Types of C operators:
C language offers many types of operators. They are
  • Arithmetic operators
  • Assignment operators
  • Relational operators
  • Logical operators
  • Bit wise operators
  • Conditional operators (ternary operators)
  • Increment/decrement operators
  • Special operators

S.no Types of Operators Description
1 Arithmetic operators These are used to perform mathematical calculations like addition, subtraction, multiplication, division and modulus
2 Assignment operators These are used to assign the values for the variables in C programs.
3 Relational operators These operators are used to compare the value of two variables.
4 Logical operators These operators are used to perform logical operations on the given two variables
5 Bit wise operators These operators are used to perform bit operations on given two variables.
6 Conditional (ternary) operators Conditional operators return one value if condition is true and returns another value is condition is false.
7 Increment/decrement operators These operators are used to either increase or decrease the value of the variable by one.
8 Special operators &, *, sizeof( ) and ternary operators.
