(C++) Counting duplicates in an array, and then moving that counted number to a corresponding position in a separate array [closed]

Closed 9 years ago.

I've just begun learning to code c++, so please bear with me, my knowledge is very very limited. This is my first program written from scratch. I'm writing a program that looks at a hand of five cards, and then tells the user it's type, such as royal flush, straight, etc.

First, I have the user input their hand, and then store that hand into an array.

What I need to do is then search through that array for duplicates (such as there being two 3's in the array), count the number of duplicates (2 in this instance), and then put that number 2 into another array at the corresponding position of the card.

For example: User has a hand of S11H11D11C11S10 (S - spades, H - Hearts, D- Diamond, and C - Clubs) The number 11 here represents a Jack, with an Ace being a rank 1 and a King a rank 13.

So the user has 4 jacks in their hand, and a 10 of spades.

I need the program to count those four jacks, and then put into another array at the 11th spot. This will tell me the user has four cards, and they are Jacks.

Since you only need to find duplicate ranks, you can do it like this:

int dupCounter[13];
for (int i=0; i<13; i++)
{
    dupCounter[i] = 0;
}
for (int i=0; i<5; i++)
{
    dupCounter[usrhand[i*2+1]-1] ++;
}
