#include <stdio.h>
int main()
{
    long long sum = 0;
    int i;
    for (i = 1; i <= 1000000000; i++)
	sum += i;
    printf("%lld\n", sum);
}

So I need the variable "I" capable of storing a 10 digit number.
I need "sum" capable of storing a 20 digit number.
I need a comparison with 1000000000 or a loop that can run a counted
1000000000 times.
The I need to print out the generated number.

Inc operation.
    Carry in Add to cell, if cell is 10 zero it and move right.
    repeat
    Run back to start.

Add operation.
    Add Carry + Cell+2n to Cell, repeat until no carry nor numbers.

    Run back to start.

Print opration.
    Run to end of number, print in reverse.
