What is wrong with this and how do I make it correct?

Answer 1

Paul

The program you are given takes a positive number N as input.
Complete the program to calculate the sum of all numbers from 1 to N inclusive.

Sample Input
4

Sample Output
10

1+2+3+4

int N = Convert.ToInt32(Console.ReadLine());
int sum = 0;

//your code goes here
for (int i = 1; i <= N; i++){
sum += i;

Answer 2

Can you tell us what the code is supposed to do. The code coach is for PRO only? I can't see it.

Answer 3

Paul I managed to do it but, but don’t understand how. The code is supposed to sum up every number that is from 1 to N. Ex. N=5, then the answer would be 15, because 1+2+3+4+5=15 and etc.

Answer 4

{
int N = Convert.ToInt32(Console.ReadLine());
int sum = 0;
int sum1 = 0;

//your code goes here
for(;sum<N;sum+=1)
{

}
Console.WriteLine(sum);

}
This is the closest I got. I don’t know how to add all results of each loop together

Answer 5

It should be sum <= N
In the loop you should add every value of sum to sum1. And you should print sum1 after the loop is finished.
