Operators
Understanding Operators in C Programming
Introduction to Operators (ऑपरेटर्स का परिचय)
Operators symbols हैं जो variables और values पर operations perform करते हैं। C में विभिन्न प्रकार के operators होते हैं।
Operators are symbols that perform operations on variables and values. C has various types of operators.
Key Points (मुख्य बिंदु):
- Operators को उनके functionality के according categorize किया जाता है
- Operators are categorized according to their functionality
- प्रत्येक operator का अपना precedence और associativity होता है
- Each operator has its own precedence and associativity
- Operators का उपयोग expressions बनाने के लिए किया जाता है
- Operators are used to form expressions
Arithmetic Operators (अंकगणितीय ऑपरेटर्स)
Arithmetic operators mathematical operations perform करते हैं:
Arithmetic operators perform mathematical operations:
| Operator (ऑपरेटर) | Description (विवरण) | Example (उदाहरण) |
|---|---|---|
| + | Addition (जोड़) | a + b |
| + | Addition | a + b |
| - | Subtraction (घटाव) | a - b |
| - | Subtraction | a - b |
| * | Multiplication (गुणा) | a * b |
| * | Multiplication | a * b |
| / | Division (भाग) | a / b |
| / | Division | a / b |
| % | Modulus (शेष) | a % b |
| % | Modulus | a % b |
// Arithmetic operators example
int a = 10, b = 3;
int sum = a + b; // 13
int difference = a - b; // 7
int product = a * b; // 30
int quotient = a / b; // 3
int remainder = a % b; // 1Relational Operators (संबंधपरक ऑपरेटर्स)
Relational operators values के बीच comparison करते हैं:
Relational operators compare values:
| Operator (ऑपरेटर) | Description (विवरण) | Example (उदाहरण) |
|---|---|---|
| == | Equal to (बराबर) | a == b |
| == | Equal to | a == b |
| != | Not equal to (असमान) | a != b |
| != | Not equal to | a != b |
| > | Greater than (बड़ा) | a > b |
| > | Greater than | a > b |
| < | Less than (छोटा) | a < b |
| < | Less than | a < b |
// Relational operators example
int a = 10, b = 20;
if (a < b) {
printf("a is less than b\n");
}
if (a != b) {
printf("a is not equal to b\n");
}Logical Operators (तार्किक ऑपरेटर्स)
Logical operators multiple conditions को combine करते हैं:
Logical operators combine multiple conditions:
| Operator (ऑपरेटर) | Description (विवरण) | Example (उदाहरण) |
|---|---|---|
| && | Logical AND (और) | a && b |
| && | Logical AND | a && b |
| || | Logical OR (या) | a || b |
| || | Logical OR | a || b |
| ! | Logical NOT (नहीं) | !a |
| ! | Logical NOT | !a |
// Logical operators example
int age = 25;
int hasLicense = 1;
if (age >= 18 && hasLicense) {
printf("Can drive\n");
}
if (!hasLicense) {
printf("Cannot drive\n");
}Operator Precedence (ऑपरेटर प्राथमिकता)
Operator precedence define करता है कि कौन सा operation पहले evaluate होगा:
Operator precedence defines which operation is evaluated first:
| Precedence (प्राथमिकता) | Operators (ऑपरेटर्स) |
|---|---|
| Highest (सबसे ऊंची) | () [] -> . |
| Highest | () [] -> . |
| High (ऊंची) | ! ~ ++ -- + - * & |
| High | ! ~ ++ -- + - * & |
| Medium (मध्यम) | * / % |
| Medium | * / % |
| Low (कम) | + - |
| Low | + - |
// Operator precedence example
int result = 5 + 3 * 2; // Result is 11, not 16
// Multiplication (*) has higher precedence than addition (+)Best Practices (सर्वोत्तम प्रथाएं)
