Simple program #8 (Source code to print prime number from x to y)

Enter starting number: 1

Enter last number: 50

O/p:

List of prime number:

2 3 5 7 11 13 17 19 23 29 31 37 41 43 47

The program is written in C# programming language and will accept a starting number and a ending number as input. The logic of the program is to find the prime number between these two numbers.

Note: Read articles on how to use Loops and Conditions.

Let’s find out a simple and easy way to code the program.

Practical Implementation:

using System;

namespace patternProblem.Simple_program

{

    class Simple8   //print prime number from x to y

    {

        static void Main(string[] args)

        {

            Console.Write("Enter starting number: ");

            int startNumber = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter last number: ");

            int lastNumber = Convert.ToInt32(Console.ReadLine());

            int i = 0;

            int j = 2;

            int count = 0;

            Console.WriteLine();

            Console.WriteLine("-----Output-----");

            Console.WriteLine();

            Console.WriteLine("List of prime number: ");

            for (i = startNumber + 1; i < lastNumber; i++)

            {

                for (j = 2; j < i; j++)

                {

                    if (i % j == 0)

                    {

                        break;

                    }

                }

                if (i == j || i == 1)

                {

                    Console.Write(i + " ");

                    count++;

                }

            }

            Console.WriteLine(); Console.WriteLine();

            Console.WriteLine("Total prime number found: " + count);

            Console.ReadKey();

        }

    }

}

Output:

The input numbers are 1 and 50. The program will find all the prime number between these two numbers. The output is shown below:

Enter starting number: 1

Enter last number: 50

List of prime number:

2 3 5 7 11 13 17 19 23 29 31 37 41 43 47
