Difference between #define and global variables
#define MAX 9


Structure and typedof
struct card{ };
typedof struct card Card;


Only local variables (not allowed to use global variables)


Check valid input
int count;
if(count = scanf("%d", &pnPlayers)!=1) { };



Check valid input with while loop (in case of input is string type)
int count
while((count=fgetc(stdin))!='\n'){ };
** fgets is better instead of fgetc



Using ctrncpy()
#define MAX_CARDS 52

    int i = 0;
    for(i=0; i<MAX_CARDS; i++) {
        deck[i].rank = ranks[i%MAX_RANKS];
        strncpy(deck[i].suit, suits[i/MAX_RANKS], MAX);

Swap with rand()


 for(i=0; i<MAX_CARDS; i++) {
        swapper = rand() % MAX_CARDS;
        temp = deck[i];
        deck[i] = deck[swapper];
        deck[swapper] = temp;
