guessing game program problem

Nov 12th, 2007

i have been fooiling around with my program for class trying to get it to work, but now i get this error message:
error C2064: term does not evaluate to a function taking 1 arguments
it is referring to this part of the program:
num = (rand() + time(0)) % 1000;
could anyone explain what i did wrong and how i can fix it. thank you
here is the program. i have been having problems doing this correctly so i hope this works

It looks like you have a couple of things mixed up. There was just a great thread on using random numbers. before you use rand() you will want to seed the generator with a random variable first. That is done by using

 C++ Syntax (Toggle Plain Text) 
srand((unsigned)time(0))
srand((unsigned)time(0))

Use that before you use rand(); and then just use

 rand() % 1000;
 rand() % 1000;

here is the link to the Thread on random numbers: http://www.daniweb.com/forums/thread1769.html

delete int time then use srand((unsigned)time(0))

> int noofgamesplayed;
noofgamesplayed++; Is using it without it being defined.
cout << "You played " << noofgamesplayed << " games"; Is also using it without it being defined.

int noofgamesplayed = 0; Now we're cooking!.

guessing game problems AAAAUUUGGHHH

Nov 13th, 2007

i have been working on this program for the last month and it is driving me nuts. i have been listening to all the advice you guys have been giving me and somehow i keep getting a debug error. could someone pleeeeaaasssseee look over what i have and tell me how or what i have to fix. the program should ask (at the end of the guesses or when they get the answer) if they want to play again and react accordingly. it should also display some summary information including number of games played, number of correct guesses and average number of guesses it took to get the right answer. i really need this project to work. it is for half my grade. any help would be greatly appreciated. here is what i have.

#10

Nov 13th, 2007

when i go to debug it gives me a warning:
run time check #3: the variable 'noofgamesplayed' is being used without being defined. i have been getting this message constantly. also when i build the solution, i get 2 warnings:
warning C4101: 'ncount' : unreferenced local variable
and
warning C4700: uninitialized local variable 'noofgamesplayed' used
I am at my wits end. any help is appreciated
