Another question about syntax

Group,
Again, self teaching has its limitations.
Below is code that ultimately will answer question 3: design a program that finds all numbers from 1 to 1000 whose prime factors, when added together, sum up to a prime number.
I am starting with a string limit of 1 to 100 to keep it manageable.
I have labeled each unique output with a new name so ultimately I can harvest them. I think a few more iterations will gt me all that I need.
The problem is,in the code below, the output starts at twenty. I do not understand why it does not output starting at least at 4 / 2 = 2.
Can anyone help me?
Thank in advance,
Dan

Code:

---

#include <iostream>
#include <string>

using namespace std;



int i;
int j;
int k;
int l;
int m;

int main ()
{


    // determine what the numbers prime factors are
for ( int i = 2; i < 100; i++)
{

    for ( int j = 2; j < i; j++ )
    {
        if ( i % j == 0 )
        {
        int k = i / j;

            cout << i << " i" << " div " << j << " j" << " = " << k << " k" << "\n";

            if ( k % j == 0)
            {
                int l = j;
                int m = k / l;
                cout << "\t" << " and " << k << " k" << " div " << l << " lj" << " = " << m << " m" << "\n";

            }

        }

    }
}

}

The number of lines you output are likely exceeding the size of the console window buffer - which means the first bunch of lines are lost.

When you have long outputs like this, consider writing the data to a file instead of (or in addition to) stdout, so you can examine everything that was printed.

Matticus,
Thanks for the help. You are saying that I am getting the results that I want and thereby can use them in the next step, it is just that they are not being printed. If I reduce my scope to 50 I would see them.
Writing the data (output) to a file is later in my learning path. Is it simple to describe?
Thanks again,
Dan

Well, they are getting printed, but the console window only has a certain amount of space before previous information is "scrolled off" the top.

Likely - have you tried?

My knowledge lies with C, not C++, but there are plenty of tutorials online that explains file I/O. One of them is here.

C++ File I/O Tutorial - Cprogramming.com

Just don't read from a file into a char array (use std::string). You might get a buffer overflow. I should notify webmaster of that old unsafe code o_O
