How do I generate random chars and integers within a method so that the method can be called in main() and so that the method generates random chars and integers together. I do not want a method that genrates chars and another methods that generates integers.

Do you want them one at a time, maybe alternating chars and ints, or do you want a parameter that tells how many to generate? What do you want to use the randomly generated values for?Greg Bacon– Greg Bacon2009-11-28 18:59:54 +00:00Commented Nov 28, 2009 at 18:59

You can write a method like (assuming you want only lower case English characters, you can extend it):
void generate(char& ranChar, int& ranNmber)
{
//Generate a random number in the range 0-25 and add the ascii value 'a'
ranChar = rand() % 26 + 'a';
ranNumber = rand();
}
int main()
{
//Seed the random number generator with the current time
srand(time(NULL));
char ch;
int n= 0;
generate(ch,n);
return 0;
}

What is the 27th letter of the English alphabet? :D
You could use boost::tuple, like this:
boost::tuple<int, char> gen () {
// srand() etc
return make_tuple(rand(), (rand() % ('z' - 'a' + 1)) + 'a');
}
