Operators in C

Arithmetic Operators

#include<stdio.h>  // Include the standard input-output library

int main() {
    // Arithmetic operations
    int a = 10, b = 5;
    int sum = a + b;  // Addition
    int difference = a - b;  // Subtraction
    int product = a * b;  // Multiplication
    int quotient = a / b;  // Division
    int remainder = a % b;  // Modulus

    // Print results
    printf("Sum: %d\n", sum);
    printf("Difference: %d\n", difference);
    printf("Product: %d\n", product);
    printf("Quotient: %d\n", quotient);
    printf("Remainder: %d\n", remainder);

    return 0;
}
        

Explanation: This program demonstrates the use of arithmetic operators: addition, subtraction, multiplication, division, and modulus. It prints the results using printf.

Relational Operators

#include<stdio.h>  // Include the standard input-output library

int main() {
    // Relational operations
    int a = 10, b = 5;

    // Check relational conditions
    printf("a > b: %d\n", a > b);
    printf("a < b: %d\n", a <</span> 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;
}
        

Explanation: This program demonstrates the use of relational operators: greater than, less than, greater than or equal to, less than or equal to, equal to, and not equal to. It prints the results using printf.

Logical Operators

#include<stdio.h>  // Include the standard input-output library

int main() {
    // Logical operations
    int a = 1, b = 0;

    // Check logical conditions
    printf("a && b: %d\n", a && b);
    printf("a || b: %d\n", a || b);
    printf("!a: %d\n", !a);

    return 0;
}
        

Explanation: This program demonstrates the use of logical operators: logical AND (&&), logical OR (||), and logical NOT (!). It prints the results using printf.

Bitwise Operators

#include<stdio.h>  // Include the standard input-output library

int main() {
    // Bitwise operations
    int a = 5, b = 3;

    // Perform bitwise operations
    printf("a & b: %d\n", a & b);
    printf("a | b: %d\n", a | b);
    printf("a ^ b: %d\n", a ^ b);
    printf("~a: %d\n", ~a);
    printf("a << 1: %d\n", a << 1);
    printf("a >> 1: %d\n", a >> 1);

    return 0;
}
        

Explanation: This program demonstrates the use of bitwise operators: AND (&), OR (|), XOR (^), NOT (~), left shift (<<), and right shift (>>). It prints the results using printf.

Assignment Operators

#include<stdio.h>  // Include the standard input-output library

int main() {
    // Assignment operations
    int a = 10;
    int b;

    // Perform assignment operations
    b = a;  // Simple assignment
    printf("b = a: %d\n", b);

    b += 5;  // Add and assign
    printf("b += 5: %d\n", b);

    b -= 2;  // Subtract and assign
    printf("b -= 2: %d\n", b);

    b *= 3;  // Multiply and assign
    printf("b *= 3: %d\n", b);

    b /= 4;  // Divide and assign
    printf("b /= 4: %d\n", b);

    b %= 3;  // Modulus and assign
    printf("b %= 3: %d\n", b);

    return 0;
}
        

Explanation: This program demonstrates the use of assignment operators: simple assignment (=), add and assign (+=), subtract and assign (-=), multiply and assign (*=), divide and assign (/=), and modulus and assign (%=). It prints the results using printf.

Increment and Decrement Operators

#include<stdio.h>  // Include the standard input-output library

int main() {
    // Increment and decrement operations
    int a = 10;

    // Perform increment operations
    printf("a: %d\n", a);
    printf("++a: %d\n", ++a);  // Pre-increment
    printf("a++: %d\n", a++);  // Post-increment
    printf("a: %d\n", a);  // Value after post-increment

    // Perform decrement operations
    printf("--a: %d\n", --a);  // Pre-decrement
    printf("a--: %d\n", a--);  // Post-decrement
    printf("a: %d\n", a);  // Value after post-decrement

    return 0;
}
        

Explanation: This program demonstrates the use of increment (++) and decrement (--) operators. It prints the results using printf.
