### Simple program

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: If you are new to C# and Console Application. Try to code First C# Program

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

}
}
}

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
