QN015. Write a program to print sum of 1 to 100.

---

1. Objective

To print the sum of numbers from 1 to 100.

2. Theory

In this program, we use for loop to generate numbers from 1 to 100. Initialize sum variable as 0 at the begining to store the sum of all numbers and print the result.

3. Source Code

public class Qn015{
public static void main(String[] args){
int sum = 0;
for(int i=1;i<=100;i++)
{
sum+=i;
}
System.out.println("Sum of 1 to 100 is " + sum);
}
}

4. Output

Sum of 1 to 100 is 5050

5. Conclusion

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