Operators In C
In C programming, operators are symbols that represent specific actions or calculations. Operators are used to manipulate values and perform operations in a program. Here are the different types of operators in C:
| Operator Type | Description |
|---|---|
|
Arithmetic |
Used to perform mathematical calculations on numeric values, such as addition, subtraction, multiplication, division, and module. |
|
Relational |
Used to compare two values and determine their relationship, such as less than, greater than, equal to, and not equal to. |
|
Logical |
Used to perform logical operations on boolean values, such as logical AND, logical OR, and logical NOT. |
|
Bitwise |
Used to manipulate individual bits of a numeric value, such as bitwise AND, bitwise OR, and bitwise XOR. |
|
Assignment |
Used to assign a value to a variable, such as simple assignment, add and assign, and bitwise OR and assign. |
|
Conditional |
Used to perform a conditional operation, such as the ternary operator. |
|
Miscellaneous |
Used for various purposes, such as the address-of operator, the pointer operator, and the size-of operator. |
Operators are an essential part of programming, and understanding their behavior and usage is critical for writing efficient and effective programs. Table of operators example with its name and sign .
| Arithmetic Operators | ||
|---|---|---|
| Operator Name | Operator Sign | Example |
| Addition | + | int sum = 3 + 5; |
| Subtraction | - | int difference = 7 - 2; |
| Multiplication | * | int product = 4 * 6; |
| Division | / | float quotient = 10.0 / 3.0; |
| Modulo/Remainder | % | int remainder = 10 % 3; |
| Increment | ++ | int x = 5; x++; |
| Decrement | -- | int y = 7; y--; |
| Relational Operators | ||
|---|---|---|
| Operator Name | Operator Sign | Example |
| Less Than | < | if (x < y) { ... } |
| Greater Than | > | if (x > y) { ... } |
| Less Than or Equal To | <= | if (x <= y) { ... } |
| Greater Than or Equal To | >= | if (x >= y) { ... } |
| Equal To | == | if (x == y) { ... } |
| Not Equal To | != | if (x != y) { ... } |
| Logical Operators | ||
|---|---|---|
| Operator Name | Operator Sign | Example |
| Logical AND | && | if (x > 0 && y > 0) { ... } |
| Logical OR | || | if (x > 0 || y > 0) { ... } |
| Logical NOT | ! | if (!(x > 0)) { ... } |
| Bitwise Operators | ||
|---|---|---|
| Operator Name | Operator Sign | Example |
| Bitwise AND | & | int z = x & y; |
