I've written the winning conditions for pair, high card and three of a kind. However, I am very confused on how to write the winning conditions for a royal flush, straight flush, four of a kind, full house, flush, and straight. Can anyone here please point me in the right direction? I would greatly appreciate it.

My code is below:

Code:
```#include <iostream>

int placeBETONE, placeBETTWO, placeBETTHREE, placeBETFINAL;
int card[7];
int suitC[7];
int rankC[7];

const char* rank[] = {"Ace", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};
const char* suit[] = {"Hearts!", "Spades!", "Diamonds!", "Shamrock!"};

//	int random;
