Well... I'd rather not give out a solution, but I can give you a really large hint. I'd give a reference to the standard library, but I think it makes more sense if you show that you know how to do it (I'm assuming this is some sort of assignment?). See if this helps! :)
Assuming you have an array with the numbers 1-10...
1 2 3 4
for(int i = 9; i > 4; i--)
{
//Copy the elements into the last 5 spaces of a different array.
}
I like thecodewall's solution! But, somehow I don't think the OPs teacher will feel the same...
P.S.: Albatross is right Guys. Posting complete solutions to obvious homework problems will not help anyone to learn C++. Especially if you don't even bother to explain your code.
