Instructions: I made the function as it is, because it reduces code to a minimum, and you could also add custom suits... be creative!

This was good.

srand() was seeded,but where did you use the rand() function?

There's no need to use rand... srand will seed anything random from the source (here using the system clock) So, random_shuffle() is basically a random function. =)

i changed this: // put the string together if (i < 10) str = i+48; // ASCII value of the number to this: // put the string together if (i == 1) str = "Ace"; if ((i > 1) && (i < 10)) str = i+48; // ASCII value of the number it now says 'Ace' instead of 1 :)
