random strings?

[Bobit]

I cant figure out how to get a random string from an array, can someone please help me. I put my code below.

thanx

#include <ctime>
#include <cstdlib>
#include <iostream>
#include <stdlib.h>
using namespace std;
int main()
{
string allcards[52] = {"2c", "2d", "2h", "2s", "3c", "3d", "3h", "3s", "4c", "2d", "4h", "4s", "5c", "5d", "5h", "5s", "6c", "6d", "6h", "6s", "7c", "7d", "7h", "7s", "8c", "8d", "8h", "8s", "9c", "9d", "9h", "9s", "10c", "10d", "10h", "10s", "Jc", "Jd", "Jh", "Js", "Qc", "Qd", "Qh", "Qs", "Kc", "Kd", "Kh", "Ks", "Ac", "Ad", "Ah", "As"};
srand(time(NULL));
string card = rand(allcards);
cout << card;
system("PAUSE");
return 0;
}

string card = allcards[ (rand() % 52) ];

try

#include <ctime>
#include <cstdlib>
#include <iostream>
#include <stdlib.h>
using namespace std;
int main()
{
    string allcards[52] = {"2c", "2d", "2h", "2s", "3c", "3d", "3h", "3s", 
                           "4c", "4d", "4h", "4s", "5c", "5d", "5h", "5s", 
                           "6c", "6d", "6h", "6s", "7c", "7d", "7h", "7s", 
                           "8c", "8d", "8h", "8s", "9c", "9d", "9h", "9s", 
                           "10c", "10d", "10h", "10s", "Jc", "Jd", "Jh", "Js", 
                           "Qc", "Qd", "Qh", "Qs", "Kc", "Kd", "Kh", "Ks", 
                           "Ac", "Ad", "Ah", "As"};
    srand(time(NULL)); 
    int cardnum = rand() % 52;
    string card = allcards[cardnum]; 
    cout << card;

    return 0;
}

rand() returns a value from 0 to 32767, not a string

You only need one of <cstdlib> and <stdlib.h>, preferably the former.
