Operators in C
The symbols that are used to perform Arithmetic (mathematical), logical, and relational operations in the C language are called C operators.
Types of Operators and Examples.
Operator consists of the following types:
Arithmetic Operators in C:
The addition is denoted by a + sign. We use addition to add two variables.
Subtraction is denoted by a – sign
Multiplication is denoted by a * sign
The division is denoted by a / sign
modulus (remainder) %: The mod operator in the C programming language is used to find the remains(remainder of a division.
/*Program of Arithmetic Operator*/
#include<stdio.h>
void main()
{
int a,b,c;
clrscr();
printf(“enter the value of a and b and c”);
scanf(“%d%d”,&a,&b);
c=a+b;
printf(“The Answer + is=%d”,c);
c=a-b;
printf(“\nThe Answer -is=%d”,c);
c=a*b;
printf(“\nThe Answer * is=%d”,c);
c=a/b;
printf(“\nThe Answer / is=%d”,c);
c=a%b;
printf(“\nThe Answer % is=%d”,c);
getch();
}
Relational Operators in C:
Relational operators in the C language are used to relate one operand to the other. The relational operators are: < Specifies that the left-hand operand is less than the right-hand operand
<= Specifies that the left-hand operand is less than or equal to the right-hand operand
> Specifies left-hand operand is greater than the right-hand operand
>= Specifies that the left-hand operand is greater than or equal to the right-hand operand
== Specifies that the left-hand operand is equal to the right-hand operand
!= Specifies that the left-hand operand is not equal to the right-hand operand
/*Program of Relational Operator*/
#include<stdio.h>
void main()
{
int x,y;
clrscr();
x=5;
y=3;
printf(“greater=%d”,(x+y)>8);
printf(“\ngreaterequals=%d”,(x+y)>=7);
printf(“\nless than=%d”,(x+y)<9);
printf(“\nless than equals=%d”,(x+y)<=7);
printf(“\ndouble equals=%d”,(x+y)==8);
printf(“\nnot equals=%d”,(x!=y));
getch();
}
Logical Operators in C:
The C programming language provides the following binary logical operators for programs:
&&: Operation AND: returns true if both operands are true
||: Operation OR: returns true if a single operand or both operands are true
^^: Operation XOR: returns true if exactly one operand is true
/*Program of Logical Operator*/
#include<stdio.h>
void main()
{
int a,b,c;
clrscr();
a=10,b=20,c=8;
printf(“logical and=%d”,(a<=b)&&(b>c));
printf(“\n logical or=%d”,(b==c)||(b>=a));
printf(“\n logical not=%d”,!(a!=c));
getch();
}
Bitwise Operator in C(binary operator):
C language provides the following binary logical operators for programs:
&: Performs AND operation
|: Performs OR operation
^: Performs XOR operation
<<: Performs Shift operation, i.e., left shifting the left-hand operand by the number of bits specified by the right-hand operand
>>: Performs Shift operation, i.e., right shifting the left-hand operand by the number of bits specified by the right-hand operand.
The shift operators are used to move bits left or right in a given integer value. Shifting left will consume empty bit positions on the right-hand side of the result, producing zeroes
/*Program of Bitwise Operator*/
#include<stdio.h>
void main()
{
int a,b,c;
clrscr();
a=10,b=11;
c=a&b;
printf(“bitwise and=%d”,c);
c=a|b;
printf(“\nbitwise or=%d”,c);
c=a^b;
printf(“\n bitwise xor=%d”,c);
c=a<<2;
printf(“\n left shift=%d”,c);
c=a>>2;
printf(“\n right shift=%d”,c);
getch();
}
Assignment Operators in C:
The C programming language provides the following binary logical operators for programs:
=: Equates the left-hand operand equal to the right-hand expression value
+=: Increments the left-hand operand specified by the right-hand expression value
-=: Decrements the left-hand operand specified by the right-hand expression value
*=: Multiply the left-hand operand specified by the right-hand expression value
/=: Divide the left-hand operand specified by the right-hand expression value
%=: Modulo the left-hand operand specified by the right-hand expression value
|=: Performs Bitwise OR operation between the left-hand operand with the right-hand expression value
&=: Performs the Bitwise AND operation between the left-hand operand with the right-hand expression value
^=: Performs the Bitwise XOR operation between the left-hand operand with the right-hand expression value
/*program of Assignment Operator*/
#include<stdio.h>
void main()
{
int a,b,c;
clrscr();
a=b=c=10;
printf(“a equal=%d”,c);
printf(“\nb equal=%d”,b);
printf(“\n c equal=%d”,a);
a+=2;
printf(“\nplus equal=%d”,a);
a-=2;
printf(“\nminus equal=%d”,a);
a*=2;
printf(“\n multiply equal=%d”,a);
a%=2;
printf(“\n mod equal=%d”,a);
getch();
}
