cards

[ui uiho]

im making a program which simulates poker. i need a way to evaluate if the player has a flush, straight flush, or 4 of a kind. i am just wondering if there is any quick way to do this without a whole set of if statements. here is my code at the moment, note that i cannot edit the cpp file for the assignment, only the main.cpp.

main.cpp -

void newshift(aCard,int,DeckofCards &);  
bool sortorder(const aCard &a, const aCard &b); 
void swap(aCard &, aCard &); 
void sort(aCard[]);   
int quat();

aCard operator+(aCard a, int i){//not sure if i need this
    aCard temp;
    temp.suit = a.suit; 
    temp.value = a.value + i; 
    return temp; 
}

int main(){
    int wager = 0; 
    int bank = quat(); 
    
    DeckofCards deck; deck.shuffle(); aCard hand[5]; 
    
    for(int i = 0; i < 5; i++){hand[i] = deck.deal();}//deal first hand
    sort(hand); //sorts hand
    
    displayHand(hand, "Your cards so far..."); //displays hand
    
    

    return EXIT_SUCCESS;

note: i did write the cpp file i can only comment it. so i cannot change or add any functions within the class.
