Algorithms, Flowcharts and Packages for Figuring out Prime Numbers

Programming World – On this tutorial, I’ll talk about examples of algorithms, flowcharts and applications on easy methods to decide prime numbers utilizing numerous programming languages ​​starting from PHP, Python, C++ and Java.

For these of you who’re on the lookout for an understanding of what algorithms and flowcharts are, you’ll be able to learn tutorials about algorithms and flowcharts on the programming world website.

Algorithms, Flowcharts and Packages for Figuring out Prime Numbers

Numbers are an essential ingredient in arithmetic. There are lots of varieties of numbers and certainly one of them is prime numbers. A chief quantity is a quantity that solely has 2 elements, particularly the number one and the quantity itself. Which means prime numbers are solely divisible by 1 or by the quantity itself.

Examples of Prime Numbers:

  • 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47 …and so forth

That is slightly clarification about prime numbers, so mainly prime numbers are numbers which are divisible by 1 and the quantity itself.

Algorithm for Figuring out Prime Numbers

The next is an algorithm for figuring out rhyme numbers

  1. Begin
  2. Enter quantity worth (a)
  3. Test with the modulus to seek out out the rest of the results of dividing by 1 and the quantity itself (a)
  4. If the modulus/the rest of the quotient of the quantity (a) with 1 is the same as 0 and the quantity (a) with the quantity itself (a) is the same as 0 then it’s a prime quantity, if it’s not equal to 0 then it’s not a primary quantity.
  5. Show Prime Quantity or Not Prime Quantity standing
  6. Completed

The method above is the method of discovering the standing of the quantity entered whether or not it’s a Prime Quantity or Not a Prime Quantity.

Subsequent, we’ll talk about how the flowchart seems like.

If you wish to make flowcharts simply, you should use Microsoft Visio 2003, as a result of I often use that model, however if you wish to use one other model, it is higher.

If you wish to obtain Microsoft Visio 2003, you’ll be able to click on the hyperlink right here.

Subsequent, we’ll enter this system creation stage ranging from PHP, Python, C++ and Java.

Program for Figuring out Prime Numbers

After the examples of algorithms and flowcharts for figuring out prime numbers have been mentioned, we’ll then transfer on to the tutorial on easy methods to implement them in a program, both in PHP, Python, C++ or Java applications.

Instance Program for Figuring out Prime Numbers Utilizing PHP

From the algorithm and flowchart that we created above about easy methods to decide prime numbers, we now implement it right into a program utilizing native PHP.




Figuring out Prime Numbers

Enter Quantity:

increase for ($i = 1; $i <= $bilangan; $i++) { if ($bilangan % $i == 0) { $dibagi=$dibagi+1; } } // seperti penjelasan jika bilangan prima hanya bisa dibagi 2 kali // oleh angka dibawahnya if ($dibagi == 2) { echo $bilangan . " adalah bilangan prima"; } else { echo $bilangan . " bukan bilangan prima"; } } ?>

Save the code above with the title index.php into the xampp/htdocs/name_folder folder then check it in your browser.

Instance Program for Figuring out Prime Numbers Utilizing Python

From the algorithm and flowchart that we made above about easy methods to decide prime numbers, we now implement it right into a program utilizing Python.

quantity = enter(“Enter the quantity you wish to verify: “) quantity = int(quantity) divisor = 2 whereas quantity % divisor != 1 and quantity % divisor != 0: divisor = divisor + 1 if divisor == quantity: print( “Quantity”, quantity, “Is a Prime Quantity”) else: print(“Quantity”, quantity, “Not a Prime Quantity”)

Copy and paste the code above, then run it within the code editor that you simply often use.

Instance Program for Figuring out Prime Numbers Utilizing C++

From the algorithm and flowchart that we made above about easy methods to decide prime numbers, we now implement it right into a program utilizing C++.

Create the venture first, then copy the supply code beneath:

#together with

utilizing namespace std; int primary() { cout << "## C++ Program to Discover Prime Numbers ##" << endl; cout<<"====================<< "Masukkan Bilangan : "; cin >>n; // 0 and 1 are usually not prime numbers if (n == 0 || n == 1) { quantity = false; } else { for (i = 2; i <= n / 2; i++) { if (n % i == 0) { divider = i; quantity = false; Relaxation; } } } cout<

You copy and paste the code above, then run it with the C++ editor that you simply often use.

Instance Program for Figuring out Prime Numbers Utilizing Java

From the algorithm and flowchart that we created above about easy methods to decide prime numbers, we now implement it right into a program utilizing Java.

Create the venture first, then create a file title known as Prime Numbers, then copy the supply code beneath:

import java.util.*; public class PrimeNumbers { public static void primary(String[] args) { int quantity,i,divided; Scanner enter = new Scanner(System.in); System.out.print(“Enter quantity: “); num = enter.nextInt(); divided = 0; // carry out a loop // carry out division utilizing looping // if the quotient is 0 or is divisible then $divided will increase for (i = 1; i <= quantity; i++) { if (quantity % i == 0) { divided=divided +1; } } // as defined if a primary quantity can solely be divided 2 occasions // by the quantity beneath it if (divide == 2) { System.out.println(Integer.toString(quantity) + " Is a primary quantity"); } else { System.out.println(Integer.toString(quantity) + " Not a primary quantity"); } } }

That is my clarification about algorithms, flowcharts and applications for figuring out prime numbers utilizing the programming languages ​​PHP, Python, C++ and Java. In case you have any questions, please write them within the feedback column.
