## Operators in C++ language

Operators:
• Operators are symbols and used to perform some mathematics operations.
• There are 6 kinds of operators,
1.Arithmetic operators:
• This is normal mathematic operations such as,
Example program for the arithmetic operator:

### #include<iostream.h> #include <conio.h>  void main()  {     int a,b;     clrscr();     cout<<"\n Enter a and b value:";     cin>>a>>b;     cout<<"\n Addition value is:"<<(a+b);     cout<<"\n Subtraction value is:"<<(a-b);     cout<<"\n Multiplication value is:"<<(a*b);     cout<<"\n Division value is:"<<(a/b);     cout<<"\n Modulo value is:"<<(a%b);     cout<<"\n a++ value is:"<<a++;     cout<<"\n b-- value is:"<<a--;    getch(); }

Output:
2. Relational Operators:
• It is used to compare two or more data.
Note:
• These logical operators mostly used in conditions.
3. Logical Operators:
• It is used to combine simple relational statements into more complex expressions.
4. Assignment Operators:
• These operators are used to getting the result in the same variable(input/output).
Example program for the assignment operator:

### #include<stdio.h>  #include <conio.h>  void main()  {     int a;     clrscr();     cout<<"Enter a  value:";     cin>>a;     a+=20;     cout<<"a value is:"<<a;     getch(); }

Output:

5. Conditional Operators (? :)
• It checks itself the condition and executes the statement depending on the condition.
Syntax:
Condition?exp1:exp2;
Example program for the conditional operator:

### #include<iostream.h> #include <conio.h>  void main()   {      int a=5,b=3,big;     clrscr(); big=a>b?a:b;   cout<<"\n Biggest value is: "<<big;   getch();   }

Output:

6. Bitwise Operators:
• It is used to manipulate the data at a bit level and it operates on integer only.
Binary table

Bitwise AND(&):
• The truth table for ‘ & ‘is shown below(It means True=1 and false=0.)
a=7 of binary code:0111
b=8 of the binary code is:1000
The result of the a&a value is 0000(i.e 0).

Example program for the bitwise AND operator:

### #include <iostream.h> #include<conio.h> void main() {                    unsigned int a;                    unsigned int b;                    int c = 0;                             clrscr();                    cout<<"\n Enter a and b value : ";                    cin>>a>>b;                    c = a&b;                        cout<<"\n Bitwise AND of a&b value is:"<<c;                    getch();  }

Output:

Bitwise OR(|):
• The truth table for ‘ | ‘is shown below
a=7 of binary code:0111
b=8 of the binary code is:1000
The result of a|b value is 1111(i.e 15).

Example program for the bitwise OR operator:

### #include <iostream.h> #include<conio.h> void main() {                    unsigned int a;                    unsigned int b;                    int c = 0;                             clrscr();                    cout<<"\n Enter a and b value : ";                    cin>>a>>b;                    c =a|b;                           cout<<"\n Bitwise OR of a|b value is: "<<c;                    getch();  }

Output:

Bitwise Exclusive OR(^):
• The truth table for ‘ ^ ‘is shown below
a=13 of binary code:1101
b=8 of the binary code is:1000
The result of a^b value is 0101(i.e 5).

Example program for the bitwise Exclusive OR operator:

### #include <iostream.h> #include<conio.h> void main() {                    unsigned int a;                    unsigned int b;                    int c = 0;                             clrscr();                    cout<<"\n Enter a and b value : ";                    cin>>a>>b;                     c =a^b;                           cout<<"\n Bitwise Exclusive OR of a^b value is: "<<c;                    getch();  }

Output:

Bitwise Shift left (<<):
• The bitwise shift left operator is used to move the bits from right to left in storage.
• Each box called bits and a=6 and a<<1 then a=12.
Explanation:

Result: a of left shit value is 12.

Example program for the bitwise shift left operator:

### #include <iostream.h> #include<conio.h> void main() {                    unsigned int a;                    int c = 0;                             clrscr();                    cout<<"\n Enter a  value : ";                    cin>>a;                    c =a<<1;                        cout<<"\n Bitwise left shit of a value is: "<< c;                    getch(); }

Output:

Bitwise Shift right(>>):
• The shit right is similar to the left shit.
• This operator is used to forward the bits from left to right in storage.
• For example, If a=6 and a>>2 then its value is 3.

Explanation:

Result: a of right shit value is 3.

Example program for the bitwise shift right operator:

### #include <iostream.h> #include<conio.h> void main() {                    unsigned int a;                    int c = 0;                             clrscr();                    cout<<"\n Enter a  value : ";                    cin>>a;                    c =a>>1;                        cout<<"\n Bitwise right shit of a value is: "<< c;                    getch(); }

Output:
Bitwise One's complement(~):
• The truth table for ‘ ~ ‘is shown below

If a=6(binary code is 0110),
and ~a(0111) value is 7.
using a negative signature for one's complement(~a=-7).

Example program for the bitwise one's complement operator:
