Write a complete program that asks user to input 12 numbers of any types or domain (i.e. positive or negative) and record user's response into, an array.

Process the input by manipulating it so that the numbers are arranged in the array in an ascending order (e.g. -1.2, -1, 0, 3, 4, 4.05, 4.1, 5).

After the manipulation is complete, print the resulting values in the array in one line.

here is what i got



#include <iostream>
using namespace std;

int main(void)
{
double Numbers[12];

cout<<"Enter 12 numbers: ";

for ( int x = 0; x < 12; x++ )
cin>> Numbers;

cout<<endl;
}

i know i gotta do something like "x + 1 == 12" or something...but duno what
hope u guys can help me out

Are you supposed to sort after all data is read, or AS you read it in?
The first is much, much easier than the second.

Here's an example of the first - a simple bubble sort after the fact.
Note that for testing, I made the number of inputs to read as a constant (so you can just do 5 for testing, then up it to 12).
Also note I haven't done anything with the rounding - it will print the full double.

#include <stdio.h>

#define NUM 5

void printArray(double a[])
{
   int x=0;
   printf("\nYou entered:\n");
	for (x=0; x<NUM; x++)
	{
      printf("%lf ", a[x]);
	}
   printf("\n");
}

void sortArray(double a[])
{
  int i,j; 
  double tmp; 
  
  for (i=0; i<NUM; i++)
     {
     for (j=NUM-1; j>i; j--) 
        {
        if (a[j] < a[j-1]) 
           {
           tmp = a[j];
           a[j] = a[j-1];
           a[j-1] = tmp;
           }
        }
     }
}

int main(int argc, char *argv[])
{
   double numbers[NUM];
   double i;
   int x;

	printf("Please enter %d numbers.\n", NUM);
	for (x=0; x<NUM; x++)
	{
      scanf("%lf", &i);
      numbers[x] = i;
	}
   
   sortArray(numbers);
   printArray(numbers);
	return 0;
}

Sample output from Unix terminal:
Unix >> cc testNumbers.c
Unix >> a.out
Please enter 5 numbers.
3
5
6
0
-12

You entered:
-12.000000 0.000000 3.000000 5.000000 6.000000
Unix >> cc testNumbers.c
Unix >> a.out
Please enter 5 numbers.
34
36.5
-23.6
12
5

You entered:
-23.600000 5.000000 12.000000 34.000000 36.500000
