How to iterate numbers to a limit by addition

Question

Here is the code I have right now:

for(int i=0; i< 35; ++i)
{
    int a = 1;
    a+=1;
    Console.WriteLine(a);
}

The output is:

2
2
2
...

and so on, until the loop terminates.

What I want to do is add the previous two numbers to make the nest number then so on all the way to 34.

This is how you can achieve what you want:

//Initializing the elements
int a = 0;
int b = 1;
int c = 1;

Console.WriteLine(a); //Typing the 0'th element
Console.WriteLine(b); //Typing the first element

for(;c <= 34; c = a + b) {
    Console.WriteLine(c); //Typing the actual element
    a = b;
    b = c;
}
