Operators

Operators

An operator is an symbol used to perform operations in programming 👉[+, -, *, /]

Ex: 👉3+4 , hence here (+)is an operator.

Types of operators

*Arithmetic Operators

*Relational Operators

* Logical Operators

*Bitwise Operators

*Assignment Operators

Arithmetic Operators

Operator
+	Addition
-	Subtraction
*	Multiplication
/	Division
%	Modulus

move on to code👇

#include <stdio.h>

int main()

{

    int a, b;

    a = 34;

    b = 12;

    printf("a + b = %d\n", a+b);

    printf("a - b = %d\n", a-b);

    printf("a * b = %d\n", a*b);

    printf("a / b = %d\n", a/b);

    printf("a / b = %d\n", a%b);

    return 0;

}

Relational Operators

Operator	Description
==	Is equal to
!=	Is not equal to
>	Greater than
<	Less than
>=	Greater than or equal to
<=	Less than or equal to

move on to code👇

#include <stdio.h>

int main()

{

    int a, b;

    a = 34;

    b = 34;

    printf("a + b = %d\n", a==b);

    return 0;

}

Logical Operators

Operator	description	Example
&&	Logical AND operator. If both the operands are non-zero, then the condition is true.	(A && B) is false
||	Logical OR operators. If any of these two operands is non-zero, the condition became true.	(A || B) is true
!	Logical NOT operator. It is used to reserve the logical state of its operand. If condition is true, then Logical NOT operator will make it false.	!(A && B) is true

move on to code👇

#include <stdio.h>

int main()

{

    int a, b;

    a = 34;

    b = 34;

    printf("a && b = %d\n", a&&b);

    return 0;

}

it will return 👉1 (because the value of integer is true)

where as,

#include <stdio.h>

int main()

{

    int a, b;

    a = 0;

    b = 34;

    printf("a && b = %d\n", a&&b);

    return 0;

}

it will return 👉0 (because the value of integer is false)

Bitwise Operators

a	b	A & b	A | b	A ^b
0	0	0	0	0
0	1	0	1	1
1	1	1	1	0
1	0	0	1	1

move on to code👇

#include <stdio.h>

int main()

{

    int a, b;

    a = 2;

    b = 3;

    printf("a + b = %d\n", a & b);

    return 0;

}

it will return 👉2 (because 0 and 1 = 2), first it will convert it into binary form, and work as bit by bit.

Other bitwise operators

~ is the binary one's complement operator.

<< is the binary left shift operator.

>> is the binary right shift operator.

Assignment Operators

operator	Description
=	Single assignment operator. Assign values from right side operand
+=	Add AND assignment operator. It adds the right to left operand and assigned the result to the left operand.
-=	Subtract AND assignment operator. It adds the right to left operand and assigned the result to the left operand.
*=	Multiplication AND assignment operator. It adds the right to left operand and assigned the result to the left operand.
/=	Division AND assignment operator. It adds the right to left operand and assigned the result to the left operand.

Miscellaneous operators

Operator	Description	Example
Sizeof()	Return the size of variable	Will return int’s size
&	Returns the address of variable	Returns the actual address of variable
*	Pointer to variable	*a:
?:	Conditional expression	If condition true(X) Otherwise(Y)

Operator precedence in C

Category	Operator	Associativity
Postfix	() [] ->,++ - -	Left to Right
Unary	+ - ! ~ ++ - - (type)* & sizeof	Right to Left
Multiplicative	* / %	Left to Right
Additive	+ -	Left to Right
Shift	<<>>	Left to Right
Relational	<<= >> =	Left to Right
Equality	== !=	Left to Right
Bitwise AND	&	Left to Right
Bitwise xOR	^	Left to Right
Bitwise OR	|	Left to Right
Logical AND	&&	Left to Right
Logical OR	||	Left to Right
Conditional	?:	Right to Left
Assignment	= += -= *= /= %=>>= <<=&=^= |=	Right to Left
comma	.	Left to Right

note: In programming languages, The associativity of an operator is a property that determines how operators of the same precedence are grouped in the absence of parentheses.

    This is basically based on [BODMAS].
