Operators in C Language explained with 3 Examples

a) Arithmetic

b) Relational

c) Logical

d) Bitwise

e) Increment & Decrement operators   

f) Assignment operators

a) Arithmetic operation:-

These operators to calculate mathematical operations.these are-, +,*,%,÷.

  Subtraction(-)

  • it is used to subtract two operands
  • A-B=1
  • A=3,B=2

 Addition (+)

  • It is useful to add two operands
  • A+B=5  (refer example 3)

  Multiplication (*)

  • It is used to multiplies two operands
    A*B=6 

  Division (/)

  • It is used to divides numerator by de-numerator 
  • A/B=1  (refer example 1&2)

%Remainder

  •  It is useful to get remainder
  •  A%B=0

 

Example 1)Division:-


                int a, b;
       float c;
       c=a/b
           
Result :
                 a=10
                  b=3
                 3.000
                 To get 3.333 in result
                 We have to small change see below program

Example 2)Division

               Int a, b;
               Float c;
               c=a/b*1.0

Example 3)Addition:-

             int a, b;
              float c;
             C=a+b

b ) Relational operators

These operators are used to compare two Numbers, ==,>,>,<
if the condition is true them the result will be 1 otherwise result will be 0

Example 1)

              int a, b, c;
              a=10;
              b=3;
              c=a==b;
Now c is zero condition is false

Example 2)

int a,b,c;
a=100;
b=55;
c=a> b;
now c is one because condition is true;

C) Logical operators

In these  operation every operator perform different operation
&&
||
!

         Truth table for && operator


           T  T T
           T  F  F
           F  T  F
           F  F  F

  Truth table for | operator

           T  T  T
           T   F  T
           F  T  T

Example 1

           int a,b,c;
            a=100;
            b=400;
            c=a==b&&b> 300;
Now c=0; because condition is false
Note: In these example1 we are using && operator

Example 2

           int a,b,c;
           a=100
           b=400
            c=a== b|| b> 300;
Now c=1, observe conditions b> 300 satisfied so result is true

D) Bitwise operators

These operators are performed on bits

Example 1)

              a=25;
               b=13;
               c=a/b;
              Result is 29
Explanation
        25→11001
       13→01001
             11101
