Csharp:Print all prime numbers between 1 to 100 using do-while loop
Csharp:Print all prime numbers between 1 to 100 using do-while loop
In this tutorial, we will discuss the concept of the Csharp:Print all prime numbers between 1 to 100 using do-while loop
In this post, we will learn how to print all prime numbers 1 to 100 using do-while loop in C# programming language with Example program.
Prime number
The number that can be divided by 1 and itself. it is called a prime number
for Example 2,3,5,7,11,13…
Csharp:Print prime numbers between 1 to 100 using do-whie loop
Print prime numbers between 1 to 100 – method 1
In this program, the user declares and initializes variables then it will print prime numbers from 1 to 100, using the do-whie loop in the C# language.
Program 1
//C#:Print all prime numbers between 1 to 100 using do-while loop
using System;
namespace primeNumber
{
class first1toNPrime
{
static void Main(string[]args)
{
Console.WriteLine("print prime number between 1 to 100");
bool isPrime=true;
var i=2;
do{
var j=2;
do{
if(i!=j && i%j==0){
isPrime=false;
break;
}
j++;
}while(j<=100);
if(isPrime){
Console.Write(i+",");
}
isPrime=true;
i++;
}while( i<=100);
Console.ReadKey();
}
}
}
When the above code is executed, it produces the following result
print prime number between 1 to 100 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97,
Print prime numbers between 1 to 100 – method 2
In this program, the user declares and initializes variables then it will print prime numbers from 1 to 100, using the do-whie loop in the C# language.
Program 2
//C# program to print all prime numbers between 1 to 100 using do-while loop
using System;
namespace primeNumber
{
class first_N_Prime
{
static void Main(string[]args)
{
int i=1,count=0;
Console.WriteLine("Prime numbers between 1 to 100 ");
int n=0;
do{
count=0;
int j=1;
do{
if(i%j==0)
count++;
j++;
}while(j<=i);
if(count==2){
Console.Write(i+",");
}
i++;
n++;
}while( n<100);
}
}
}
When the above code is executed, it produces the following result
Prime numbers between 1 to 100 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97,
