C Programming Operators and Expressions

The sign that are used to complete  logical & mathematical operations in c programs are called operators.consider the expression A+B*10 inside +,*. are operators, A,B are  variables, and 10 is constant. and A+B*10 is an expression.There are different types of operators in c which are below.

Types of operators in C Programming

There are different types of operators in c language which are as follows.

  • Arithmetic operators
  • Relational operators
  • Logical operators
  • Assignment operators
  • Increment and Decrement operators
  • Conditional operators
  • Bitwise operators
  • Special operators

Arithmetic operators

An arithmetic operator is a mathematical  function that takes two operands and performs a calculation on them for taking the result. Arithmetic operators  are used in common and most computer languages contain a set of  operators that can be used within the equations to execute  a number of types of sequential calculation.
Operator Descreption of operators Example
+ Adds two  or more operands A + B+C = 30
Used to Subtracts operand. B − C= -10
* Multiplies  operands. A B C = 200
/ Divides numerator by de-numerator. A / B = 2
% Remainder  or Modules Operaotr of after an integer division. B % A = 0
++ Incremental operator increases the integer value by one. A++ = 11
-- Decrement operator decreases the integer value by one. A-- = 9

Relational operators

A relational operator comparison  the  two values  quantitatively. Using  the Relational Operator segment In C Programming we can compare the value stored between two variables and depending on the result we can follow different blocks using Relational Operator in C languag.

Relational operator in c programming

Special operators

The special  operator is a symbol that tells the compiler to perform specific mathematical or logical operations. in c some special operators are as follows.

Bitwise Operators

Bitwise operator works on bits and perform bit-by-bit operation. The truth tables for &, |, and ^ is as follows −

p q p & q p | q p ^ q
0 0 0 0 0
0 1 0 1 1
1 1 1 1 0
1 0 0 1 1

increment/decrements operators

The increment   operators is  unary operators that add or subtract one represented by (++) sign. The increment operator is used to increase the value by one,on the other side the Decrements operator is used to decrease the  value of the  variable by  one  (1)the decrements operator is denoted by –.

logical operators

The idea  of the  logical operators is very  simple. They permission  the  program to make a decision based on multiple conditions either true or false . Every  operand is considered a condition that can be evaluated to a true or false values.There are three types of  logical operators in c these are   (OR), && (AND), ! (NOT)  they are called.

Operator Description Example
&& If both the operands are non-zero, then the condition becomes true. It is called logical and operator (B && C) is false.
|| If any of the two operands is non-zero, then the condition becomes true. It is called logical or operator (AB|| C) is true.
! It is used to reverse the logical state of its operand. If a condition is true, then Logical NOT operator will make it false. !(B && C) is true.

conditional operators

The  Conditional operators return one value if the condition is true and returns false if the condition is false.There are three conditional operators in c these operators  tells the compiler to perform specific mathematical  functions. C language is rich in built-in operators and provides the following types of operators − Arithmetic Operators. Relational Operators. Logical Operators.

Assignment operator

The assignment operator is used to give the new value to a variable,Assignment operators can also be used for the  logical operations such as bit wise logical operation.

Operators Precedence in C

Operator precedence determines how an expression is evaluated which opertor will work first and which will work last. Seom perators have higher precedence than others; for example, the multiplication operator has a higher precedence than the others.
