I have no C experience but a 2sec google search for this ...

#include<math.h>
srand(time(null));
rand_num = (int)((rand()%RAND_MAX)*9.0) + 1;

im getting negative numbers i dont get it, is it my code or my compiler, im using miracle c

 

[FishBoy]

i think my compiler is dumb, can anyone point me out to a better C complier for windows, coz i tried compiling it on unix and i got all zeros

you can get microsoft and borland command line compilers free, then there is dev-c++ and some other thing.

Check out www.programmerstools.org run by a friend of mine, got links to the freebie programming stuff out there.

ok i got the borlan complier, but how do i set the path and stuff like that coz i dont understand anything form the readme.txt, it's telling me to creat a .cfg and append the current path etc.. i dont know how to do those can you help me out

 

[LordOfLA]

I have no clue either, not a c/c++ type myself I just knew you could get them.

Use Dev-C++ it doesnt need any configuration, and works quite well.
Or if you are in Linux use gcc, which should be installed by default

Dev-C++

As for random ints.

int rndnmr (int high, int low) {
        return int ( rand() / (RAND_MAX + 1.0) * (high-low+1) + low );
}

Enjoy . Do make sure to run srand( time(NULL) ); somewhere in your code before you use that function. Best bet is it place it in main() right after the decleration.
