Better yet, don't declare i as a float. From the look of
your code you only need it as an int.

I'm a beginner in C programming language,
we use TurboC2.0 compiler in the labs but I have apple so I use Xcode
at home to practice. We solved an array program in the lab
today, the program read in at most 20 real numbers into an array, and
then print the number closest to the average of the 20 numbers. But
when I try the same problem at home Xcode compiles with errors saying
that (array subscript is not an integer) also (stray '\32' in
program), I never had this kind of problems with other programs which
works in TC2.0 . The source code is as follows:
#include
<stdio.h>
#include
<math.h>
int
main()
{
float
a[20],sum,i,aver,k,ref,diff;
sum=0;
i=0;
while(i<20
&& scanf("%f",
&a[i]) ==1)
{
sum+=a[i];
i+=1;
}
aver=sum/i;
printf("\n");
ref=a[0];
diff=fabs(aver-a[0]);
for(k=0;k<i;k+=1)
{
if(fabs(a[k]-aver)<diff)
{
ref=a[k];
diff=fabs(a[k]-aver);
}
}
printf("ave:%g
closest:%g\n",aver,ref);
}
