[Ask]Card combine and shuffle

Icenel (31)
Hi everyone. I got a problem with combine
I have project to make card game without GUI(CMD view), for 4 players(me + 3 CPU)
The card have 4 elements : Diamonds, Clubs, Hearts, Spade
This is part of my code

#include <stdio.h>
#include <string.h>
#include <ctype.h>
#include <stdlib.h>

int main( void ){
	
	char Diamond[13][15] = {"2 Diamond", "3 Diamond", "4 Diamond", "5 Diamond", "6 Diamond", "7 Diamond", "8 Diamond", "9 Diamond", "10 Diamond", "Jack Diamond", "Queen Diamond", "King Diamond", "As Diamond"};
	char Club[13][15] = {"2 Club", "3 Club", "4 Club", "5 Club", "6 Club", "7 Club", "8 Club", "9 Club", "10 Club", "Jack Club", "Queen Club", "King Club", "As Club"};
	char Heart[13][15] = {"2 Heart", "3 Heart", "4 Heart", "5 Heart", "6 Heart", "7 Heart", "8 Heart", "9 Heart", "10 Heart", "Jack Heart", "Queen Heart", "King Heart", "As Heart"};
	char Spade[13][15] = {"2 Spade", "3 Spade", "4 Spade", "5 Spade", "6 Spade", "7 Spade", "8 Spade", "9 Spade", "10 Spade", "Jack Spade", "Queen Spade", "King Spade", "As Spade"};

Next step is combine these 4 elements into 1, and shuffle it with random (rand)...
The question is how to combine and random it and split for 4 players(each 13 cards) ?
I try with strcat but it doesn't work...

You could have a char deck[52][15] and strcpy them all, but that would be a lot of work. You could also have a char* deck[52]; and for(int i = 0; i < 13; i++) deck[i] = Diamond[i]; and so on.
Then to shuffle you'd have to choose two random integers [0;52) and swap deck[i1] with deck[i2]. Repeat it a bunch of times.

Did you try searching for an answer before posting here? On the very first page of a google search for "std random shuffle" http://www.cplusplus.com/reference/algorithm/random_shuffle/
