QN013. Write a program to print prime numbers between 1 to 100.

---

1. Objective

To print the prime numbers between 1 to 100.

2. Theory

To achieve the result we use for loop to generate numbers between 1 to 100. For the calculation of prime number we use modulo(%) operator inside the if statement.

3. Source Code

public class Qn013{
public static void main(String[] args){
int number;
for(number=1; number<=100; number++)
{
int count=0;
for(int i=2; i<=number/2; i++)
{
if(number%i==0)
{
count++;
break;
}
}
if(count == 0 && number != 1)
System.out.print(number + "\t");
}
}
}

4. Output

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

5. Conclusion

In this way, I would like to conclude that, we can get prime numbers between 1 to 100 by using for loop and some conditions.
