randomize symbols in slot machine game

Bog (8)
In this assignment you will create a slot machine emulator. This slot machine will cost 1 credit to play and pay out 5 credits for each line you win on. It generates symbols from a pool of 10 different symbols and scrolls them on three different rollers – each displaying three symbols.

My code so far. I'm stuck on how to make the symbols randomly generate and also how to make it so if the user gets 3 of the same symbols horizontally/vertically/ or diagonally it rewards the user with 5 credits.

    cout << symbol6 << symbol7 << symbol8 << endl;

Non-Ambigious Hint: IF symbols 3, 4 AND 5 match THEN the user wins 5 credits. Think on the bolded portions of the sentence above, let us know if you need more.

Yes, but than how would I make it randomize?

This should be good enough for a school assignment: http://www.cplusplus.com/reference/clibrary/cstdlib/rand/
and
http://www.cplusplus.com/reference/clibrary/cstdlib/srand/


A guy on this site wrote a much better Randomizer and if I can find it I will link it here for you. But using it a school assignment at your apparent level would raise too many questions.

How do I make it so it re-rolls the slot machine after the user enters a key??

Try using a loop.

Try that code. It's simple but works and shows stuff pretty clear. rand() randoms a number but is every time the same. You should first do srand which is found in
