array and pointing randomly

This is a discussion on array and pointing randomly within the C Programming forums, part of the General Programming Boards category; so this is my problem: Code: #include<stdio.h> #include<string.h> #include<stdlib.h> #include<time.h> #define DECKSIZE 52 #define VALUE 9 #define FACE 4 typedef ...

    array and pointing randomly

    so this is my problem:
    Code:
    #include<stdio.h>
    #include<string.h>
    #include<stdlib.h>
    #include<time.h>
    #define DECKSIZE 52
    #define VALUE 9
    #define FACE 4
    
    typedef struct {
            int value;
            char* suit;
            char* name;
    }Card;
    
    Card cards[DECKSIZE];
    char *faceName[]={"two","three","four","five","six","seven","eight","nine",
                      "ten","jack","queen","king","ace"};
    char *suitName[]={"spades","diamonds","hearts","clubs"};
    void printDeck(){
    int i;
    for(i=0;i<DECKSIZE;i++){
                    printf("%s of %s \n",cards[i].name,cards[i].suit);
                    if((i+1)%4==0  && i!=0) printf("--------------------\n\n");
    }
    }
    void shuffleDeck(){
    srand(time(NULL));
    int this;
    int that;
    Card temp;
    int i;
    for (i=0;i<10;i++){
            this=rand()%DECKSIZE;
            that=rand()%DECKSIZE;
    while(this==that)that=rand()%(52+1);
    //printf("shuffle  card%d with card %d\n", this, that);
    temp=cards[this];
    cards[this]=cards[that];
    cards[that]=temp;
    }
    }
    int main(){
            int suitCount=0;
            int faceCount=0;
            int i;
            for(i=0;i<DECKSIZE;i++){
                    if(faceCount<9){
                    cards[i].value=faceCount+2;
                    }else{
                            cards[i].value=10;
                    }
                    cards[i].suit=suitName[suitCount];
                    cards[i].name=faceName[faceCount++];
                    if(faceCount==13){
                            cards[i].value=11;
                            suitCount++;
                            faceCount=0;
                    }
            }
    {
    
    //printDeck();
    //shuffleDeck();
    //printDeck();
    //printDeck();
    
            }/*
    int c;
    int rdm();
            {printf("To play blackjack press 1:");scanf("%d", &c);}
    if (c==1)
    do{
            printf("this still works\n");
    break;
    }while(c==1);
    if(c!=1)
    do{
            printf("Please only press 1.\n");
    break;
    }while(c<=1);
    */
    int P_hand, D_hand;
    srand(time(NULL));
    P_hand=rand() %52+1;
    D_hand=rand() %52+1;
    printf("%s of %s,----%s of %s\n ",&P_hand, &P_hand,&P_hand,&P_hand );
    
    shuffleDeck();
    printf("%s of %s,----%s of %s\n",&D_hand,faceName[0],suitName[2],faceName[5],suitName[1]);
    
    shuffleDeck();
            return 0;
    }
    
    }}
    ;

    so my question is how do i only print out 2 RANDOM cards on one line and 2 RANDOM cards on another?
    with the part i wrote down i can print out the whole deck in random order with the shuffle function that i wrote. but i just cant figure out how to modify this function to only print out what i need.

    keep in mind that this is a start to a blackjack game so here is a visual of my goal:

    seven of spades, ten of diamonds
    ---------------------------------------------
    six of hearts, four of clubs

    hit or stand?

    let me know if you have any advice

    If your deck is shuffled, you don't want random cards, you want the first cards off the top of the deck.

    Well, no. If your deck is shuffled, just print [0], [1], [2], and [3].
