Operators in C

Operators in C are symbols that perform operations on variables and values. They are categorized into different types based on their functionality.

Types of Operators

1. Arithmetic Operators

Used to perform mathematical operations:

• + (Addition)
• - (Subtraction)
• * (Multiplication)
• / (Division)
• % (Modulus - returns remainder)

int a = 10, b = 5;
printf("Sum: %d", a + b);

2. Relational Operators

Used to compare values:

• == (Equal to)
• != (Not equal to)
• > (Greater than)
• < (Less than)
• >= (Greater than or equal to)
• <= (Less than or equal to)

if (a > b) {
    printf("a is greater than b");
}

3. Logical Operators

Used for logical operations:

• && (Logical AND)
• || (Logical OR)
• ! (Logical NOT)

if (a > 5 && b < 10) {
    printf("Both conditions are true");
}

4. Bitwise Operators

Operate at the bit level:

• & (Bitwise AND)
• | (Bitwise OR)
• ^ (Bitwise XOR)
• ~ (Bitwise Complement)
• << (Left Shift)
• >> (Right Shift)

5. Assignment Operators

Used to assign values:

• = (Assigns a value)
• += (Adds then assigns)
• -= (Subtracts then assigns)
• *= (Multiplies then assigns)
• /= (Divides then assigns)
• %= (Modulus then assigns)

6. Increment and Decrement Operators

Used to increase or decrease values:

• ++ (Increment)
• -- (Decrement)

int x = 5;
x++;
printf("%d", x); // Outputs 6

Example Program

#include <stdio.h>

int main() {
    int a = 10, b = 5;
    printf("Addition: %d\n", a + b);
    printf("Greater: %d\n", a > b);
    printf("Logical AND: %d\n", (a > 5 && b < 10));
    return 0;
}
