Thread: shuffle deck

Code:

Hi guys!
I have created this deck and I want to shuffle it.
Could anyone help me shuffle it, and mention any mistakes???
I have to submit the assingment by tomorrow..

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define deck_size 52

int main ()
{

printf("\n --------------------\n");
printf("| The Game of 31     |\n");
printf(" --------------------\n\n");
    int z;
    int i,j,x;
    int temp;
    int initial_deck[deck_size];
    int shuffled_deck[deck_size];
    printf("Initial Deck:\n");
    
    for(z=0;z<deck_size;z++)
    initial_deck[z]=z;
    {
    for(i=1;i<14;i++)
    { 
        for (j=3;j<7;j++)
        switch (i)
        {      
        case 1: printf("|A%c|",j);
                break;
                printf("\n\n");
        case 2: printf("|2%c|",j);
                break;
                printf("\n\n");
        case 3: printf("|3%c|",j);
                break;
                printf("\n\n");
        case 4: printf("|4%c|",j);
                break;
        case 5: printf("|5%c|",j);
                break;
        case 6: printf("|6%c|",j);
                break;
        case 7: printf("|7%c|",j);
                break;
        case 8: printf("|8%c|",j);
                break;
        case 9: printf("|9%c|",j);
                break;
        case 10: printf("|10%c|",j);
                 break;
        case 11: printf("|J%c|",j);
                 break;
        case 12: printf("|Q%c|",j);
                 break;
        case 13: printf("|K%c|",j);
                 break;
                       }
          printf("\n");}
       }
system("pause");
return 0;
}

Your starting out too complicated. I would recommend starting simple, and build up the program.
