It's not executing and I dont know why.

Question

int num = Convert.ToInt32(Console.ReadLine());
int res = 1;
//your code goes here
while(num < 9)
{
Console.WriteLine(num);num+=2;
}

Answer 1

Since it is clearly stated that "... from 1 to N inclusive ..." we can initialize <res> by 2 (the nearest even number greater than 1), and then increment <res> by 2 in the while-loop body.

And again, by the "inclusive" specific, we'd use `while( res <= num)` in order to also include <num> in outputs.

Answer 2

What is the instruction?
If given input value was greater or equal to 9, the loop will not start, simply because the loop condition isn't satisfied.

Answer 3

Alright man, doing good job!
Keep it up 👍

Answer 4

Ipang
Write a program to take N numbers as input and output all even numbers from 1 to N inclusive, each on a new line.

Sample Input
9

Sample Output
2
4
6
8

Answer 5

Ipang you the man bro. I really appreciate the help. It worked.

int num = Convert.ToInt32(Console.ReadLine());
int res = 2;
//your code goes here
while(res <= num)
{
Console.WriteLine(res);res+=2;
}

Answer 6

Ipang I'm having trouble with this.

It's a for loop. I'm confused on calculating the sum.

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
