    <p>I have this function that receives a string of "chars". I'm trying to go through that string and use pointers to see if the second element is the same as the first. SO lets say I have aaabbccddd, i would want to write into an array that i have 3a, 2 bs, 2cs and 3ds. I'm really struggling in figuring out if the second string is the same as the first by using pointers. I created this temp pointer and i do temp++. THis essentially just shows everything after the second term and so on...How can i individually look at the second term and compare it to the first term with just pointers.</p> <pre><code>void RLE&lt;T&gt;::Compress(const T* input, int inSize) { delete m_Data; m_Size = 0; T * m_Data; m_Data = new T[inSize*2]; int runSize = MaxRunSize(); const T * temp; temp = input; temp++; </code></pre> <p>This part right here always gives me errors and it says that I have a Bad pointer. I understand that this essentially doesn't work because my input pointer is longer than the temp pointer i created. and my array never gets initialized</p> <pre><code> if (temp == input) { std::cout&lt;&lt;"here"&lt;&lt;std::endl; int number = 1; number++; m_Data[0] = number; m_Size++; std::cout&lt;&lt;temp; m_Data[m_Size] = *temp; } } </code></pre> <p>Any help would be much appreciated</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
