Notes

1.Bitwise Operations(Ask the user to enter two integer numbers. Perform and display the results of bitwise AND, OR, XOR, and NOT operations on the entered numbers.)
#include <stdio.h>

void bitwise_operations(int a, int b) {
printf("AND: %dn", a & b);
printf("OR: %dn", a | b);
printf("XOR: %dn", a ^ b);
printf("NOT a: %dn", ~a);
printf("NOT b: %dn", ~b);
}

int main() {
int a, b;
printf("Enter first integer: ");
scanf("%d", &a);
printf("Enter second integer: ");
scanf("%d", &b);
bitwise_operations(a, b);
return 0;
}

2.Swap Two Numbers Without Using a Temporary Variable(Swap Two Numbers Without Using a Temporary Variable: Use arithmetic operators, bitwise operators, or other techniques. (This is a classic problem where you can use addition and subtraction or XOR operations to swap the values of two variables without using a third temporary variable)

#include <stdio.h>

void swap_numbers(int *a, int *b) {
*a = *a ^ *b;
*b = *a ^ *b;
*a = *a ^ *b;
}

int main() {
int a, b;
printf("Enter first integer: ");
scanf("%d", &a);
printf("Enter second integer: ");
scanf("%d", &b);
swap_numbers(&a, &b);
printf("Swapped numbers: a = %d, b = %dn", a, b);
return 0;
}


3.Convert Fahrenheit to Celsius(Prompt the user to enter a temperature in Fahrenheit. Use arithmetic operators to convert it to Celsius and display the result. Formula)
#include <stdio.h>

void fahrenheit_to_celsius(float fahrenheit) {
float celsius = (fahrenheit - 32) * 5.0 / 9.0;
printf("%.2f Fahrenheit is %.2f Celsiusn", fahrenheit, celsius);
}

int main() {
float fahrenheit;
printf("Enter temperature in Fahrenheit: ");
scanf("%f", &fahrenheit);
fahrenheit_to_celsius(fahrenheit);
return 0;
}

4.Determine if a Number is Even or Odd Using Bitwise AND(Use the bitwise AND operator to determine if a given number is even or odd. Hint: Observe the least significant bit.)
#include <stdio.h>

void is_even_or_odd(int n) {
if (n & 1)
printf("%d is oddn", n);
else
printf("%d is evenn", n);
}

int main() {
int n;
printf("Enter an integer: ");
scanf("%d", &n);
is_even_or_odd(n);
return 0;
}

5.Determine if a Year is a Leap Year(Use logical operators to determine if a given year is a leap year. A year is a leap year if it is divisible by 4 but not by 100, or if it is divisible by 400)
#include <stdio.h>

void is_leap_year(int year) {
if ((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0))
printf("%d is a leap yearn", year);
else
printf("%d is not a leap yearn", year);
}

int main() {
int year;
printf("Enter a year: ");
scanf("%d", &year);
is_leap_year(year);
return 0;
}
6.Left Shift and Right Shift an Integer(Take an integer input from the user. Left shift and right shift the number by one position and display the results.)
#include <stdio.h>

void shift_operations(int n) {
int left_shift = n << 1;
int right_shift = n >> 1;
printf("Left shift of %d: %dn", n, left_shift);
printf("Right shift of %d: %dn", n, right_shift);
}

int main() {
int n;
printf("Enter an integer: ");
scanf("%d", &n);
shift_operations(n);
return 0;
}
