Using the bitwise AND operation, the result of 1 AND 0 is 0.

10100100 XOR 11010101 = 01110001.

A common way to detect whether a value is even or odd is to use the AND 1 operation to test if the least significant bit is set.

Combining multiple flags into a single variable can be accomplished via the OR operation.

A prime number is an integer greater than 1 that is evenly divisible by only 1 and itself. For example, the number 5 is prime be
Gemiola [76]

Answer:

The c++ program to check prime numbers is shown below.

#include <iostream>

using namespace std;

bool isPrime(int n);

bool isPrime(int n)

{

   bool prime;

   int p=0;

   

   if(n==2 || n==3)

       prime = true;

   else if(n%2 == 0)

       prime = false;

   else

   {

       for(int k=3; k<n/2; k++)

       {

           if(n%k == 0)

               p++;

       }

   

   if(p>1)

       prime = false;

   else

       prime = true;

   }

   

   return prime;

}

int main() {

   int num;

   do

   {

       cout<<"Enter a positive number."<<endl;

       cin>>num;

       if(num<1)

       {

           cout<<"Invalid number. Enter a positive number"<<endl;

           cin>>num;

       }

   }while(num<2);

   

   cout<<"The "<<num<<" is prime. "<<isPrime(num)<<endl;

   

   

}

 

OUTPUT

Enter a positive number.

-4

Invalid number. Enter a positive number

0

Enter a positive number.

101

The 101 is prime. 1

Explanation:

The user input is validated for positivity. A do while loop along with if statement is implemented for verification.

do

   {

       cout<<"Enter a positive number."<<endl;

       cin>>num;

       if(num<1)

       {

           cout<<"Invalid number. Enter a positive number"<<endl;

           cin>>num;

       }

   }while(num<1);

The test for prime number is done by using multiple if else statements and a Boolean variable prime is used.

If user inputs 2 or 3, variable prime is set to true.

Else If user inputs an even number, variable prime is set to false. This is done by taking modulo of the number upon division by 2.

Else if user inputs neither an even number nor a number less than 3, the modulus of the number is taken with divisors beginning from 3 up to half of the input number. Here, an integer variable p is used and based on its value, variable prime is set to true or false.

For this, an integer variable p is initialized to 0. A number can be completely divisible by itself or by its factors.

If the number is divisible by any of the divisors, value of variable p is increased by 1. If value of p is greater than 1, this means that the user input is divisible by more than one divisor. Hence, the given number is not a prime number and the variable prime is set to false. Otherwise prime will be set to true.

The value 1 indicates true and 0 indicates false.

In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the
rusak2 [61]

Answer:

Explanation:

def the_perfect(n):

  try: #exception handling if n is a negative number

       n > 0

   except: #return -1 if the error is reached

       return -1

  else:

        total = 0

        for i in range(1, n): #for loop from 1 to the target number

           if n % i == 0:

               total += i

   return total == n  #should return true if number is perfect number

print(perfect_number(8))
