This wont compile correctly, it says "implicit declaration of function `int random(...)'"
Code:#include <stdio.h> #include <math.h> #include <iostream.h> int main() { int topf; topf=random(5); cout<<topf; return 0; }
This wont compile correctly, it says "implicit declaration of function `int random(...)'"
Code:#include <stdio.h> #include <math.h> #include <iostream.h> int main() { int topf; topf=random(5); cout<<topf; return 0; }
there is no function called random()
Those headers are deprecated in c++ use c++ headers
math.h is unused.
At least the int main is correct.

That means you have a function that hasn't been defined but is still used in your program. In this case, the function is named random. As far as I know, there isn't a function with that name anywhere. I assume that you want a random number between one and five yes? This is how you do that:
Code:topf=rand()%5+1;
Thanks ill try that, Stoned_coder, some of the header files arent used because the prog isnt done.
EDIT: I got the same error using the other code
Code:topf=rand()%5+1;

Oops, my bad. Make sure you have this line after your #include's:
Code:using namespace std;
In C rand() lives in the header stdlib.h
In C++ std::rand() lives in the header cstdlib

And you should make a call to the srand() function prior to using rand(). That provides a "seed" for the random number. The results from the time function are a good one. For time you will need to include the ctime header which is the equivalent of c's time.h.
Code:#include <iostream> #include <ctime> using namespace std; int main(void) { srand(time(NULL)); // Only call me ONCE // Do stuff like call rand() return 0; }
