tricky interview question for C++
<p>Given the code below, how would you create/implement SR.h so that it produces the correct output WITHOUT any asterisks in your solution?</p>

<p>I got bummed by this question. I would like to know some of the different approaches that people use for this problem.</p>

<pre><code>#include &lt;cstdio&gt;
#include "SR.h"

int main()
{
    int j = 5;
    int a[] = {10, 15};
    {
        SR x(j), y(a[0]), z(a[1]);

        j = a[0];
        a[0] = a[1];
        a[1] = j;

        printf("j = %d, a = {%d, %d}\n", j, a[0], a[1]);
    }

    printf("j = %d, a = {%d, %d}\n", j, a[0], a[1]);
}
</code></pre>

<p>output</p>

<pre><code>j = 10, a = {15, 10}
j = 5, a = {10, 15}
</code></pre>

<p>Second one:</p>

<pre><code>#include &lt;cstdio&gt;
#include "SR.h"
int main()
{
    int sum = 0;
    for (int i = 1; i &lt; 100; i++) {
        SR ii(i);
        while (i--)
            sum += i;
    }
    printf("sum = %d\n", sum);
}

//The output is "sum = 161700".
</code></pre>
