int k, m;
double n, a_n, x;

printf("Enter a positive integer m:\n");
scanf("%d", &m);
printf("Enter a double -1<x<=1:\n");
scanf("%d", &x);

for(k=1; k<m+1; k++)
{
a_n = x;
printf("%2d         %8.5f\n", k, a_n);
}
}

I'm just doing something simple right now, scanning. My problem is, instead of the "x" I had made the program scan, I keep getting 0.

 1          0.00000
 2          0.00000
 3          0.00000
 4          0.00000
 5          0.00000

Any help?

scanf("%d", &x);

->

scanf("%lf", &x);

%d is for ints, %lf is for doubles.
