So I'm creating a program to play go-fish, and I'm starting with shuffling the deck and then printing it. My problems are:
I get a segmentation fault in the "shuffle" function somewhere during assigning the array values.
GCC is complaining about multi-character character constants in "deck". I don't know how else to declare a deck of cards.
I keep getting "Subscripted value is neither array, nor pointer, nor vector" when attempting to print array values.
I know there are probably a lot of obvious faults in my code. Forgive me, please. I'm a beginner.
Here is the code (main function last):
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <math.h>
#include <time.h>
int shuffle(int deck[52], int version)
{ //this is to store the shuffled deck after it is finished
int newdeck[52] = {0};
printf("In shuffle\n");
//I plan to create other combinations for a shuffled deck, but starting with only one
switch (version)
{ //this sets a value in newdeck to a value in deck, obviously mixing the order
//this is also where I get my segmentation fault.
case 1: newdeck[0] = deck[26];
newdeck[1] = deck[13];
newdeck[2] = deck[33];
newdeck[3] = deck[45];
newdeck[4] = deck[19];
newdeck[5] = deck[36];
newdeck[6] = deck[42];
newdeck[7] = deck[24];
newdeck[8] = deck[51];
newdeck[9] = deck[22];
newdeck[10] = deck[15];
newdeck[11] = deck[10];
newdeck[12] = deck[3];
newdeck[13] = deck[6];
newdeck[14] = deck[43];
newdeck[15] = deck[48];
newdeck[16] = deck[27];
newdeck[17] = deck[18];
newdeck[18] = deck[1];
newdeck[19] = deck[31];
newdeck[20] = deck[14];
newdeck[21] = deck[0];
newdeck[22] = deck[21];
newdeck[23] = deck[12];
newdeck[24] = deck[41];
newdeck[25] = deck[35];
newdeck[26] = deck[16];
newdeck[27] = deck[4];
newdeck[28] = deck[9];
newdeck[29] = deck[40];
newdeck[30] = deck[25];
newdeck[31] = deck[34];
newdeck[32] = deck[44];
newdeck[33] = deck[7];
newdeck[34] = deck[5];
newdeck[35] = deck[38];
newdeck[36] = deck[46];
newdeck[37] = deck[37];
newdeck[38] = deck[49];
newdeck[39] = deck[39];
newdeck[40] = deck[23];
newdeck[41] = deck[50];

newdeck[47] = deck[17];
newdeck[48] = deck[30];
newdeck[49] = deck[8];
newdeck[50] = deck[29];
newdeck[51] = deck[32];
break;
}
printf("Leaving shuffle\n");
//return the shuffled deck
return newdeck;
}
int main(void)
{ //declare a deck of cards.
int deck = {'2S', '3S', '4S', '5S', '6S', '7S', '8S', '9S', 'TS', 'JS', 'QS', 'KS', 'AS', '2H', '3H', '4H', '5H', '6H', '7H', '8H', '9H', 'TH', 'JH', 'QH', 'KH', 'AH', '2C', '3C', '4C', '5C', '6C', '7C', '8C', '9C', 'TC', 'JC', 'QC', 'KC', 'AC', '2D', '3D', '4D', '5D', '6D', '7D', '8D', '9D', 'TD', 'JD', 'QD', 'KD', 'AD'};
//a counter
int i;
//this is here for debugging purposes as well as the other similar occurrences
printf("Entering shuffle\n");
//shuffles the deck
deck = shuffle(deck, 1);
printf("Printing deck\n");
for ( i = 0 ; i < 52 ; i++ )
{
printf("%d ", deck[i]);//print the values in deck (now shuffled and set equal to newdeck from "shuffle" function. I also get the error "Subscripted value is niether array, nor pointer, nor vector."
}
return 0;
}
