Hey all, i've made considerable progress since February working on my C programming since February.

Code:
/* #5. ON YOUR OWN: Write a program that uses pointers to type double variables to accept 10 numbers from the user, sort them, and print them to the screen. (Hint: See Listing 16.3.) 

 p 226

#5. ON YOUR OWN: Modify the program in the previous exercise to allow the user to specify whether the sort order is ascending or descending. */

#include <stdio.h>
#include <stdlib.h>

#define MAX 5

double number[MAX];

void func1(void);
void sort(void);

int main( void )
{
	int selection = 0;

	int my_var = 0;
	
	while (1)
	{
		printf("Enter sort method\n(0) to Exit \n(1) for Ascending \n(2) for Descending\n Enter: ");
		scanf("%d", &selection);

		switch (selection)
		{
			case 0:
				puts("Exiting program...");
				exit(0);
			case 1:
				puts("\nYou entered 1.");
				my_var = 1;
				break;
			case 2:
				puts("\nYou entered 2.");
				my_var = 2;
				break;
			default:
				puts("Out of range, try again");
				break;
		}

		func1();
	}
}

void func1(void)
{
	int count;

	count = 0;
	
	for(count = 0; count < MAX; count++)
	{
		puts("\nEnter a number between 1 and 100: ");
		scanf("%lf", &number[count]);	

		if (number[count] == 0)
		{
			puts("Error!\n");
			break;
		}

		if (number[count] > 100)
		{
			puts("Error!\n");
			break;
		}

		if (number[count] < 0)
		{
			puts("Error!\n");
			break;
		}
		
	}

	sort();
}

void sort(void)
{
	int a, b, count;

	a = 0;
	b = 0;

	for(count = 0; count < MAX; ++count)
	{
		for(a = 0; a < MAX -1; a++)
		{
			if(number[count] < number[a])
			{
				b = number[count];
				number[count] = number[a];
				number[a] = b;
			}
		}
	}

	puts("\nOutput:\n");

	for(count = 0; count < MAX; ++count)
	{
		printf("%f\n", number[count]);
	}
}
The program works, in a way, however I need to figure out, whether it be sending case 1 & 2 to a separate function after each case is pressed to alternate this greater than or less than sign.

Code:
if(number[count] < number[a])
Thanks Salem for previous support on previous questions.
