		}
    }
}



My problem is that i always get 8 as the correct number. Why is this happening????


Type "computer" to guess the computers number.
Type "user" to make the computer guess your number.
computer
Guess my hidden number
8
CONGRATULATIONS!!! YOU WIN!!!
It took you 1 trys to guess correctly.

call srand before you call rand. srand seeds it and gives you a random one

That doesn't work. this is suppose to be for the bracketing search exercise and i can't get it to select a different number besides 8. i have been at it for more than a day thinking of what to do and i don't know what it is. this is really aggravating can someone please help.

i called it srand() right before rand().

no you didnt. you called it when they enter a guess not when you call rand. put one call to srand before you call randd
