Thread: Random Number Issues

I am very new to C and have been tasked to produce a program that generates 1000 random numbers (with a max of 9) and then finds the total average. I have produced the following but it only seems to return 0 as the answer.

Code:

// Program to determine the mean of 1000 random numbers //
// written by Kerim Morris 01/10/2010 //


#include <stdlib.h>

int max_count = 1000;         //declare the variables//
int count = 0;
int random_number = 0;
int random = 0;
int random_total = 0;
float mean = 0;


main()                       //start of main function//
{
{
                             
for (count = 0; count < max_count; count ++);   //loop counter to a maximum// 
                                                                   //of 1000 //

random_number = (int)(10.0*rand()/(RAND_MAX+1.0));      //produce random//
                                                                          // numbers between 0-9//


random_total = random_number + random_total;        //calculate the running //
                                                                          // total//
}
            mean = (random_total / max_count);           //calculate mean of total //
            printf("The mean of 1000 random numbers equals %f");
           
            
}

Any guidance would be appreciated.

Code:

for (count = 0; count < max_count; count ++);   //loop counter to a maximum//

I'm not quite sure what you mean, you seem to have repeated the same code I have but unfortunately there is no explanation.

Code:

for (count = 0; count < max_count; count ++);   //loop counter to a maximum//

There, that's a bit more obvious I think. At least when you've figured out that upside down, slightly off, italic exclemation point is in fact a semicolon.

1) The semicolon isn't supposed to be there is their way of saying...
Put opening brace instead.
2) Also you have en extra opening-brace after main (one too many).
3) This is incorrect:

Code:

mean = (random_total / max_count);

. You need to do

Code:

mean = ((float)random_total / max_count);

4) You need to fix your printf so that ot outputs mean.
