QN021. Write a program to print sum of prime numbers between 1 to 100.

---

1. Objective

To print sum of prime numbers between 1 to 100.

2. Theory

A number that is divisible only by itself and 1 is prime number. To generate numbers between 1 to 100 we use for loop and some if condition to check wheater the number is prime or not.

3. Source Code

public class Qn021{
public static void main(String[] args){
int number,sum=0;
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)
sum+=number;
}
System.out.print("Sum of prime number between 1 to 100 is " + sum);
}
}

4. Output

Sum of prime number between 1 to 100 is 1060

5. Conclusion

In this way, I would like to conclude that, we can calculate the sum of prime numbers between 1 to 100 using this program.
