Here is the complete explanation of Operators in C with syntax and examples:

---

⭐ Operators in C Programming

Operators are symbols used to perform operations on variables and values.

Example:

int a = 10 + 5;

Here + is an operator.

✔ Types of Operators in C

Category	Operators Included
1️⃣ Arithmetic Operators	+, -, *, /, %
2️⃣ Relational (Comparison) Operators	>, <, >=, <=, ==, !=
3️⃣ Logical Operators	&&, ||, !
4️⃣ Assignment Operators	=, +=, -=, *=, /=, %=
5️⃣ Increment/Decrement Operators	++, --
6️⃣ Bitwise Operators	&, |, ^, ~, <<, >>
7️⃣ Conditional (Ternary) Operator	?:
8️⃣ Special Operators	sizeof, &, *, , , ->

---

📌 1️⃣ Arithmetic Operators

Used to perform mathematical operations.

Operator	Meaning
+	Addition
-	Subtraction
*	Multiplication
/	Division
%	Modulus (Remainder)

Example:

int a = 10, b = 3;
printf("%d", a % b); // Output: 1

---

📌 2️⃣ Relational Operators

Used to compare two values. Output is True(1) / False(0).

Operator	Meaning
>	Greater than
<	Less than
>=	Greater than or equal to
<=	Less than or equal to
==	Equal to
!=	Not equal to

Example:

(a > b)

---

📌 3️⃣ Logical Operators

Used to combine relational expressions.

Operator	Meaning
&&	Logical AND
||	Logical OR
!	Logical NOT

Example:

if(a > b && a > c)

---

📌 4️⃣ Assignment Operators

Operator	Example	Same As
=	a = b	a = b
+=	a += 5	a = a + 5
-=	a -= 3	a = a - 3
*=	a *= 2	a = a * 2
/=	a /= 4	a = a / 4
%=	a %= 2	a = a % 2

---

📌 5️⃣ Increment & Decrement Operators

Operator	Meaning
++	Increment (Increase by 1)
--	Decrement (Decrease by 1)

Two Types:

• Pre: ++a (increment then use)

• Post: a++ (use then increment)

Example:

int a = 5;
printf("%d", a++); // Output: 5 (then becomes 6)
printf("%d", ++a); // Output: 7

---

📌 6️⃣ Bitwise Operators

Works on bits (0 or 1).

Operator	Meaning
&	Bitwise AND
|	Bitwise OR
^	XOR
~	NOT
<<	Left Shift
>>	Right Shift

Example:

int a = 5 << 1;  // 5 = 0101 → 1010 = 10

---

📌 7️⃣ Conditional / Ternary Operator

Short form of if-else

Syntax:

(condition) ? expression1 : expression2;

Example:

int a = 10, b = 5;
int max = (a > b) ? a : b;

---

📌 8️⃣ Special Operators

Operator	Meaning
sizeof	Returns size of data type/variable
&	Address of variable
*	Pointer dereference
,	Comma (evaluate multiple expressions)
->	Used with pointer to access structure member

Example:

int a;
printf("%lu", sizeof(a)); // Size of int

---

🎯 Operator Precedence (Highest to Lowest)

1. (), [], ->, .

2. !, ~, ++, --, (type) cast

3. *, /, %

4. +, -

5. <<, >>

6. <, <=, >, >=

7. ==, !=

8. &

9. ^

10. |

11. &&

12. ||

13. ?:

14. =, +=, -=, etc.

15. ,

---

✔ Simple Example Program

#include <stdio.h>
int main() {
    int a = 10, b = 3;
    printf("a+b = %d\n", a+b);
    printf("a>b = %d\n", a>b);
    printf("a&&b = %d\n", a&&b);
    return 0;
}
