could anyone explain to me, please
results obtain 10 30
20 50
30 50
40 50
50 50
in my second for loop, i leave for int nCurrentIndex=Indexzero instead of int nCurrentIndex=Indexzero+1, but i still get the results. why?

1)for (int nStartIndex = 0; nStartIndex < nSize; nStartIndex++)

2)for(int nCurrentIndex = nStartIndex + 1; nCurrentIndex < nSize; nCurrentIndex++)

thank

if (anArray[nCurrentIndex] < anArray[nSmallestIndex])

If the purpose of “nSmallestIndex” is just to temporarily hold the smallest index whilst you search the rest, wouldn’t it make more sense just to use “nStartIndex” and not bother giving “nSmallestIndex” a value of anything when it’s initialized, thus using “nSmallestIndex” Only as a temp holding place? I hope this is clear, I’m not a C++ pro like some of you. It just took me a while to understand it because of this seemingly unnecessary assignment. Please let me know if there is a good reason for doing so. Thanks -Zach
