check out: 1. rand() <-- value up to RAND_MAX 2. random(ceiling) <-- probably the one you want.. 3. randomize() - <-- to seed 4. srand(seed) <-- to initialize Gene |

You must include stdlib.h. like this: #include <iostream.h> #include <stdlib.h> Hope this solve the problem.

//beginning of program
#include <iostream.h>
#include <stdlib.h>
int main()
{
int number;
number=3D1+rand()%13;
cout << number;
return 0;
}
//end of program
Try this it worked. One stupid thing is that it gives you the same =
number everytime you use it.I have forgotten how to do if you want =
diffrent numbers every time you use the program.
Anyone knows?

//New random numder every time you run it
#include <iostream.h>
#include <stdlib.h>
#include <time.h>
int main()
{
int number;
srand (time(0));
number=3D1+rand()%13;
cout << number;
return 0;
}
//End of the program
I have just tested this program and it works and gives you new number =
every time.

Try this: #include <cstdlib> #include <ctime> using std::srand; using std::rand; num = rand()/(RAND_MAX/12); // 0-12 num++; // to eliminate zero. you can add the ++ to the above num = Regards, lstar36 On Tue, 13 Feb 2001 11:16:44 -0500 Jose Flores <jf...@ax...> writes: > what is a good simple command to get a random number from 1 to 13?

there is no random() function in dec-c++. Use Ran() lstar36 On Tue, 13 Feb 2001 15:05:18 EST Gen...@ao... writes: In a message dated 2/13/01 9:00:11 AM Pacific Standard Time, jf...@ax... writes: I get and error " implicit declaration of function 'int random(....)'

srand() should do it... You need to 'seed' the random number generator with
some random value.

random(), randomize() belong to what language?
