Runtime Error in C

Question

I am trying to solve a interest problem. Why is this code Giving Runtime error? I Cannot figure out any reason. Is it because of the use of float?

#include <stdio.h>
#include <stdlib.h>
int main(int argc, char** argv) {

    float c,temp,temp2,x;
    float r;
    int n,ans;
    scanf("%f",&c);
    if(c>0 )
    {
        scanf("%d",&n);
        if(n>0)
        {
            scanf("%f",&r);
            if(r>=0)
            {
                temp=n;
                temp2=c;
                while(temp>0)
                {
                    x=c*1200/(1200+r);
                    c=temp2+x;
                    temp--;
                }
                ans=(int)x;
                printf("%d\n",ans);
            }
        }
    }
    return 1;
}

I am Using an online gcc compiler (GCC-4.9.2) . It is just saying Runtime error. — Mandar Bhamare, Aug 07 '15 at 15:03
`c=6000 n=3 r=12' . It gives me desired output along with Runtime Error. — Mandar Bhamare, Aug 07 '15 at 15:07
What @BLUEPIXY said. Plus, for some inputs it may result in division by zero. — Eugene Sh., Aug 07 '15 at 15:08
@MandarBhamare Well I am not getting any error with the input you specified. — ameyCU, Aug 07 '15 at 15:09
See [here](http://stackoverflow.com/questions/204476/what-should-main-return-in-c-and-c) then. — Eugene Sh., Aug 07 '15 at 15:16
@MandarBhamare, please paste the error you are getting and the command you are executing. Because I successfully executed this program in my system. I didn't get any error for `c=6000 n=3 r=12`; I get the o/p `17645`. — Pawan, Aug 07 '15 at 16:21
@EugeneSh. what inputs can cause a divide by zero? The only divide I see is by (1200+r) where the OP has specifically checked that r>=0 — FredK, Aug 07 '15 at 17:06
@Pawan It was tested on an online server. The code worked fine for some of my test cases too. Just changing `return1` to `return 0` solved the error. — Mandar Bhamare, Aug 08 '15 at 19:17

Try return 0;

at the end...and it should work

Though ,I don`t know why returning more than 0 gives problem for online compiler.. It should work even with returning any int value.

Even for Netbeans `return 1` runs the problem without any problem. But on closing the output terminal , output window says **RUN FAILED (exit value 1, total time: 9s)** – Mandar Bhamare Aug 08 '15 at 19:22
