Operators:
An operator is the symbol that specify the operation or activity to be perform.
Example:
C language is very reach in operator the operators in cand be classified based on_
1. The number operant used by operator.
2. The type of operation being perform.
1. The number operant used by operator:
A mathematical expression consists of number and variable joined by operator such as +,-,*, the operator are classified in 3 category on operates.
1. Unary operator [a *, a/, a++]
2. Binary operator [a+b, 2/3, s*3]
3. Ternary operator [?;] (a>b ? a:b)
1.Unary operator: [a*, a/, a++]:
(a) Post: first use the value then update the value.
(b) Pre: first update the value then use the value.
(a) Post: 1. Post increment (a++)
2. Post decrement (a--)
Example:
If a=5
a++ then a=6
a-- then a=4
(b) Pre: 1. Pre increment (++a)
2. Pre decrement (--a)
Example:
If a=5
++a then a=6
--a then a=4
PROGRAMтд╡я╕П
(I). #include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int a=6, b=7;
a++;
++b;
--a;
--b;
b--;
printf("%d%d",a,b); // a=6, b=6;
getch();
}
OutputтЮбя╕П. 66
(II) #include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int a=6, b=7;
a=a+++b++;
b=b+++a++;
printf("%d%d",a,b);
getch();
}
OutputтЮбя╕П. 1418
2. Binary operator: [a+b, 2/3, s*3]:
Binary operators act upon a two operands to produce a new value (0 or 1).
Syntax for binary operator is:
operand1 operator operand2
3. Ternary operator: [?:] (a>b ? a:b):
If any operator is used on three operands or variable is known as Ternary Operator. It can be represented with ? : . It is also called as conditional operator.
It helps to think of the ternary operator as a shorthand way or writing an if-else statement. Programmers use the ternary operator for decision making in place of longer if and else conditional statements.
Syntax for ternary operator is:
(condition)?(statement 1):(statement 2);
Example:
(a>b)?printf('a is greater):printf("b is greater");
2. The type of operation being perform:
1. Arithmetic operator [+,-,*,%,/]
2. Assignment operator [*=,-=,+=,/=,%=]
3. Increment increase or decrease [++,--]
4. Relational operator [<=,>=,==]
5. Logical operator
6. Conditional operator [<,>,<=,>=,=][?,;]
7. Bitwise operator [~,<<,>>,&,!,^]
8. Special operator
1. Arithmetic operator:[+,-,*,%,/]:
The operator that are used to perform arithmetic operation such as +,-,*,/,% are called arithmetic operator can be classified in two types of this on the number of operants.
(I). Arithmetic binary operator
(II). Arithmetic Unary operator
2. Assignment operator:[*=,-=,+=,/=,%=]:
An operator which is used to copy the the data and result of an expression in a memory location is called assignment operator the assignment operator is donated by '=' sign
Syntax:
Variable=variable
Shorthand operator:
We can also used to shorthand and rotation for assignment operator such as-
Shorthand shorthand. Meaning
operator expression
+ = a+=10 a=a+10
- = a-=10 a=a- 10
* = a* =5 a=a* 5
/ = a/=? a=0/?
3. Increment or decrement operator:[++,--]:
These operator are very compact and powerful operators available in C language. These two operator are Unary operator use single operants are classified into two categories.
PROGRAM for increment operatorтд╡я╕П
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int x=3;
x++; //x=x+1. Post-increment(x++)
printf("%d",x);
++x; //x=x+1. Pre-increment(++x)
printf("%d",x);
getch();
}
OutputтЮбя╕П. 45
PROGRAM for decrement operatorтд╡я╕П:
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int x=3;
x--; //x=x-1. Post decrement
printf("%d",x);
--x; //x=x-1. Pre decrement
printf("%d",x);
getch();
}
OutputтЮбя╕П. 21
4. Relational operator:[<=,>=,==]:
The relational operator also called comparison operator are used to compare two Operants they are used to find the relationship between two operants are constant or variable are expressions. The relationship between these two operants in 0 or 1.
>. Greater than
<. Less than
>=. Great than equal to
<=. Less than equal to
!=. Not equal to
==. Equal to
5. Logical operator:
As we have logic gates such as AND,OR,NOT. Whose output is 1 or 0 be also have logical operators. After evaluation expression consisting of a logical operators result in either true or false. Such expression are called logical expressions.
1. [&] AND (Binary operator)
2. [||] OR (Binary operator)
3. [!] NOT (Unary operator)
1. Logical AND:
The result of logical AND operation denoted by '&&' is true if AND only if both the operants are evaluated to true if one of the operant is evaluated is false then the result is false.
If (a==b && b==c)
equilateral triangle
2. Logical OR:
The result of logical OR operation denoted by '||' is true if and only if one of the operants is evaluated is true if both the Operants are evaluated to false.
3. Logical NOT:
Logical NOT denoted by '!' can be true or false. The result is true if the Operants is false and the result is false if the Operants is true.
6. Conditional operator:
The conditional operator also called ternary operator as the name index an operator that operant and three Operants called ternary operator that is [?,|]
Syntax:
(Example 1? Example 2; Example 3;)
Example:тд╡я╕П
#include<stdio.h>
#include<conio.h>
void main();
{
int a,b,c;
scanf("%d%d",&a,&b);
c=a>b?a:b;
printf("%d",c);
getch();
}
OutputтЮбя╕ПWriting a big or a small condition will display a large condition in the output. Ex: 10
20
On display. 20
7. Bitwise operator:
The data is stored in the memory in term of binary digit,s. That is '0' or '1' some time it may be necessary manipulate these bites. The operators that are to manipulate the bits are called bitwise operators.
Operator. Description
~. Bitwise Identical [Negative]
<< Left shift
>> Right shift
& Bitwise AND
! Bitwise OR
^ Bitwise x-or
8. Special operator:
Below are some of the special operators that the C programming language offers.
Operator Discription
&. This is used to get the
address Of the variable.
Example: &a will give address
of a.
*. This is used as pointer to a
variable.
Example: *a where, *is
pointer to the variable a.
Sizeof(). This gives the size of the
variable.
Example: size of (char) will
give as 1.
EXAMPLE PROGRAM FOR & AND * OPERATORS IN C:
In this program, "&" symbol is used to get the address of the variable and "*" symbol is used to get the value of the variable that the pointer is pointing to.
#include<stdio.h>
#include<conio.h>
void main()
{
int *ptr, q;
q = 50; /*address of q is assigned of ptr*/
ptr = &q; /*display q's value using variable*/ printf("%d", *ptr);
