rand() existing variables?

is it not possible to randomize already existing variables?

char a="hi";
char b="I am";
char c="new to this";

?

Your question doesn't really make that much sense.
What is the actual problem you are trying to solve?

[I can think of at least three different things that you MAY mean - but I'm not going to post any of them, as I'd probably get it wrong anyways].

I got X number of different variables...all decleared with Char.

what I want is to "cout << variablex"

so each time the program starts it will send 1 random of the variables to the screen, then shut down
.

sry if that didn`t make much sense

Declare an array of them.
Then generate a random subscript.

so you said you have x char variables, and each time the program runs, you want one of the x char variables to print, and then exit?

Code:

---

int main()
{
    char myChars[] = { 'a', 'b', 'c', 'd' };
    // seed random number generator
    int random = // call function to generate random number from 0 to 3 inclusive

    cout << myChars[random] << endl;
}

is this logic something that your looking for? again, to me this seems like what you are asking

Also use const char* for string constants or (const) std::string.

You can't do THAT, but as suggested elsewhere, you can use an array and a random index to achieve the effect you want. But what you suggest involves runtime decisions on which variable to use, and the C or C++ languages do not support that.

Edit: And of course, if you are REALLY desperate to not create an array of your variables, you could make an array of pointers to the original variables, e.g.

Code:

---

char *a = "Hi";
char *b = "Hello";
char *c = "'Morning";
char **arr[] = { a, b, c };
...

thanx for the replies.
I did load them into a array and then randomized them.

worked wonders :)
