Random names using an array

Im currently using a switch statement for the names but i think an array would be easier but how to i get the program to randomly get a name from the array:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28

void randNames()
{
    int random;

    srand(time(NULL));

    for(int i = 0; i < 7; i++)
    {
        random = rand() % 7;
    }

    switch(random)
    {
        case 0:
            cout << "Jerry" << endl;
            break;
        case 1:
            cout << "Mike" << endl;
            break;
        case 2:
            cout << "Phil" << endl;
            break;
        case 3:
            cout << "Robert" << endl;
            break;
        case 4:
            cout << "Allen" << endl;
            break;
        case 5:
            cout << "Alex" << endl;
            break;
        case 6:
            cout << "Tim" << endl;
            break;
    }
}

Use the randomly generated number as the index for the array that contains the names:

1
2
3
4
5
6
7
std::string names[7] = 
{
    // ...
};

srand(time(0x0));
std::cout << names[(rand( ) % 6)];

why is there 0x0 instead of NULL?

It's the same thing. I use 0x0 rather than "NULL".

And when i went to my code, the computer started beeping and screwed up, what did i do wrong?
randNames() has no return statement.
So return names; ??
Nevermind i got it thanks.
0x0 is hexadecimal for 0. NULL is a #define for 0.
Do not call srand before every call to rand.

Only call srand once at program startup.
