Brushing Up On [C], What's Wrong?

[The Sand Man]

I haven't written C in a while, but I decided to brush up on it.

I'm trying to solve this problem:

User inputs values into an array, input terminates with a negative value. I then want to print out all the values in the order they were entered, then print them in ascending order.

I realize there are multiple ways to solve this problem, but this is the only one which is giving me trouble. The approach I have in this problem is to work through the array, find the lowest value, print it, then delete it.

#include<stdio.h>
#include<math.h>

int main()
{
	double x[100],v, min=0;
	int i, n, j, count;
	printf("Enter data (<0 to terminate): ");
	n=0;
	while(1)
	{
		scanf("%lf",&v);        //Scan in values
		if(v<0.0) break;        //Terminate with negative value
		x[n++]=v;               //Store in array
	}
	printf("given data:\n");
	for(i=0;i<n;i++)
	{
		printf("%5.1f",x[i]);        //Print out array values
	}
	printf("\ndata in ascending order:\n");
	count=n;
	while(count>0)
	{
		min=x[0];
		for(i=0;i<n;i++)
		{
			if(min>x[i]) min=x[i];       //Find lowest value
		}
		count--;
		printf("  %.1lf", min);              //Print lowest value
		i=0;
		while(i<(n-1))                       //Delete lowest value
		{
			if(min==x[n-1])             //Check if it's the last one, reduce length of array
			{
				n--;
				break;
			}
			if(x[i]==min)                //If it's not at the end, delete it, and overwrite array from that position onwards
			{
				for(j=i;j<(n-1);j++)
				{
					x[j]=x[j+1];
					
				}
				n--;
			}
			i++;
		}
	}
	printf("\n");
	return 0;
}

I hope you can figure out my mistake. When I input values like:
1 3 1 5 1 5 1
I get:
1 1 3 5 5 5 5 :(

Thanks for any help. :)

Cheers,

Since the program deletes by value instead of by index of the minimum numer it ends up deleteing multiple instances of "1" in the loop, resulting in left over "5"'s.

Yeah, that's what it looks like to me-- you probably meant to have a "break;" after the second n-- statement.
