Hi. Newbie question again

I have this code that randoms out 4 names on the screen and I want to save the words that are randomed out on the screen in a variable (maybe with an array?).

this is the code:

Code:
char c[4][6] = {"Tony","James","Johnny","Lars"}; 

srand((unsigned)time(NULL));

for (i=0;i<4;i++){

    j = rand() % 4;
    cout<<c[j]<<"\n";
   // code for saving c[j] names in a variable

}
I want to save the c[j] in a variable so I have all four randomed names in one variable (array?).
How do I do this?
