Array/List?
-
- I'm sorry, but I know this is a real newbie-question: how do I make an array for for instance UINT's or doubles, or CButtons? 2) Is there a possibility to determine (fast!) what the highest or lowest value in an UINT- or doubles-array or list is? I need this, because I've planned to make 1) my very own CHistogramCtrl 2) a (useless) dialog, containing one button, that devides itself into 4 new ones after clicking on it (and so on: click on one of the new buttons and it will start over again).

The lowest value is always going to be zero. The highest value is always going to be the number of elements minus 1;int nCount = (sizeof(uArray) / sizeof(UINT)) - 1;Since you are using MFC, you might want to look at theCArray-related classes. -

I'm not real sure. Even though the word 'value' was used, I took it with a grain of salt. Folks' use of words in these forums vary so much, it's hard to assume anything.
Five birds are sitting on a fence. Three of them decide to fly off. How many are left?

How much of a beginner are you? Are you a beginner of VC++/MFC only or are you also fairly new to C++? Apart from David's answer below you could also try using the vector class with the max_element algorithm. If you type "max_element" in the Help index and click on the Sample program link there is an example showing how to use it. It is also possible to use max_element on a raw array, if you find that easier to get your head round.
double histogram[] = { 1, 4, 4, 6, 1, 2, 2, 3, 1, 6, 6, 6, 5, 7, 5, 4, 4 }; int count = sizeof(histogram) / sizeof(histogram[0]); double* begin = histogram; double* end = histogram + count; double* maximum = max_element(begin, end); afxDump << "Maximum = " << *maximum << "\n"; // or use TRACEYou should also "include " Kevin -

But if I understand it well, max_element is a macro (or function, whatever) in <algorithm.h>. Is that correct? If it is, it'd really help me.
