So I've got this random function in my main. Welp, it worked yesterday, but after messing with the code and forgetting what I changed, now I keep getting this error.

error C2064: term does not evaluate to a function taking 0 arguments

And the function is:

int main()
 {
	//int n = 3000;
	srand((unsigned)time(0));
	int rand;
	int lowest=1, highest=3;
	int range=(highest-lowest)+1;

	for(int index=0; index<20; index++)
	{
		//a1 = mvx1;
		//b1 = mvy1;

		rand = lowest+int(range*rand()/(RAND_MAX + 1.0));
		cout << rand << endl;
        }
}

- So does anyone see the problem? I can't find it yet. Thanks.

You can't use rand as a variable name because it conflicts with the function rand().


And for future reference -- it would be helpful to include the line number that is part of the error message.

Try changing this line

srand((unsigned)time(0));

to this

srand((unsigned int)time(0));

EDIT: Good catch r.stiltskin, I didn't even see that

The error occurs at the line:

rand = lowest+int(range*rand()/(RAND_MAX + 1.0));

Well thanks! It was the rand. I changed it to randint and it works!
