C++ Programming Operators

An operator is  a symbol that operates on a value or  a variable. For example + is an operator to perform addition.

C has a wide range of operators to perform  various operations.           

      1 .    Arithmetical Operator

      2.    Relation Operator 

      3.    Increment / Decrement Operator  

     4 .    Logical Operation

     5.   Sizeof Operator

     6.    Assignment Operator  

     7.    Comma operator

Fig: C++ Programming Operators 

 

     1.    Arithmetical Operator

An arithmetical operator perform mathematical operations such as  addition, subtraction, multiplication, division etc on a numerical values(constants and variables).

 

Example:

 

                              I.            a+b=addition

                           II.            a-b=subtraction

                       III.            a*b=multiplication

                       IV.            a/b=division

                          V.            a%b=modulo division

Program of Arithmetical Operator

#include<iostream.h>

int main()

{

int a,b,c,d,e,f,g;

cout<<”input two number”;

cin>>a>>b;

c=a+b;

d=a-b;

e=a*b;

f=a/b;

g=a%b;

cout<<c<<d<<e<<f<<g;

return 0;

}

Output:

Input two number:

20

10

30  10   20   0 20

 
       2.    Relational Operator

A relational operator check the relationship between two operands. If the relation is true, it return 1; if the relation is false, it returns value 0.

Example:

                  I.            ==    Equal to                           5==3 is evaluated to 0

               II.            >     greater than                       5>3 is evaluated to 1

           III.            <      less than                            5<3 is evaluated to 0

           IV.            !=   Not equal to                         5!=3 is evaluated to 1

              V.            >=  greater than or equal to         5==3 is evaluated to 1

           VI.            <= less than or equal to                5==3 is evaluated to 0

Program of Relational Operator

#include<iostream.h>

int main()

{

int   a,b,c,d,e,f,g,h;

cout<<enter number”;

cin>>a>>b;

c=a>b;

d=a<b;

e=a>=10;

f=a<=20;

g=a==50;

h=a!=50;

Output:

5==5 is 1

5>5 is 0

5<5 is 0

5 !=5 is 0

5>=5 is 1

5<=5 is 1

 

        3.    Increment / Decrement  Operators

C programming has two operators increment ++ and decrement – to change the value of and operand by 1.

 Increment ++ increase the value by 1 when decrement -- decrease the value by 1.These two operators are unary operators, meaning they only operate on a single value.

 

Program of Increment / Decrement Operator

#include<iostream.h>

int main()

{

int  a=10,b=100;

cout<<”enter number”;

cin>>a>>b;

a++;

b--;

cout<<a<<b;

return0;

}

 

Output:

Enter number

++a=11

--b=99

 

4.Logical Operator

An expression containing logical operator return either 0 or 1 depending upon whether expression result true or false.

Example:

      I.            &&    AND

   II.            ||         OR

III.            !          NOT

Program of  Logical Operator

#include<iostream.h>

int main()

{

int   a=5,  b=5,  c=10,  result;

result=(a==b)&&(c>b);

cout<<“(a==b)&&(c>b) is %d \n “, result;

result=(a==b)&&(c<b);

cout<<“(a==b)&&(c<b) is %d \n “, result;

result=(a==b) || (c<b);

cout<<“(a==b) || (c<b) is %d \n “, result;

result=(a !=b) || (c<b);

cout<<“(a!=b) || (c<b) is %d \n “, result;

result=!(a!=b);

cout<<“!(a==b) is %d \n”,result;

result=!(a==b);

cout<<“!(a==b) is %d \n”,result;

return 0;

}

 

Output:

(a==b) && (c>b) is 1

(a==b) &&(c<b) is 0

(a==b) || (c<b) is 1

(a!=b) || (c<b) is 0

!(a!=b) is 1

!(a==b) is 0

 

5.Sizeof Operator

The sizeof is a unary operator that return the size of data.

Program of Sizeof Operator

#include<iostream.h>

int main()

{

int   a;

float  b;

double  c;

char  d;

cout<<“size of int=%lu byte\n”,sizeof(a);

cout<<“size of float=%lu byte\n”,sizeof(b);

cout<<“size of double=%lu byte\n”,sizeof(c);

cout<<“size of char=%lu byte\n”,sizeof(d);

return 0;

}

Output:

Size of int=4 byte

Size of float=4 byte

Size of  double=8 byte

Size of  char=1 byte

6. Assignment Operator

An assignment operator is used for assigning a value to a variable. The most common assignment operator is =.

Example:

      I.            =             a=b                        a=b

   II.            +=           a+=b                     a= a+b

III.            -=           a-=b                        a=a-b

IV.            *=           a*=b                       a=a*b

  V.            /=             a/=b                       a=a/b

VI.            %=           a%=b                     a=a%b

Program of Assignment Operator

#include<iostream.h>

int main()

{

int  a=5,  c;

c=a;

cout<<c;

c  +=a;

cout<<c;

c  -=a;

cout<<c;

c *=a;

cout<<c;

c  /=a;

cout<<c;

c %=a;

cout<<c;

return 0;

}

 

Output:

C=5

C=10

C=5

C=25

C=5

C=0

     7.     Comma Operator

Comma operator are used to link related expression together.

For Example:

int  a,  c=5,  d;
