Question

C programing

Write a program to sort numbers in either descending or ascending order. The program should ask the user to enter positive integer numbers one at a time(hiting the enter key after each one) The last number entered by the user should be -1, to indicate no further numbers will be entered. Store the numbers in an array, and then ask the user how to sort the numbers (either descending or ascending). Call a function void sortnumbers ( int numbers[ ], int size, int ascending ) to sort the numbers. Size is the total number of numbers entered. If the argument ascending is 1, the numbers should be sorted in ascending order, if it is 0, the numbers should be sorted in descending order. The sortedNumbers function should call a swap numbers should be sorted in decending order. The sortednumbers function should call a swap function, which will swap the contents of two array elements. Lastly, display the sorted numbers.

output:

#include<stdio.h>
int array[100];
void main()
{
   int i=0,asc,j,item;
   printf("Enter element into array last element should be -1\n");
   while(1)
   {
       scanf("%d",&item);
       if(item<0)
       break;
       else
       {
       array[i]=item;  
       i++;  
       }
          
}
printf("given array\n");
   for(j=0;j<i;j++)
   printf("%d\t",array[j]);
      
   printf("\nenter 1 for ascending 0 for descending\n");
   scanf("%d",&asc);
  
   sortnumbers(array,i-1,asc );
   printf("sorted array\n");
   for(j=0;j<i;j++)
   printf("%d\t",array[j]);
  
}
sortnumbers( int numbers[ ], int n, int asc )
{
int p,j,temp;  
for(p=0;p<n-1;p++)             // Loop for Pass
{

for(j=0;j<=n-1;j++)
{
if(asc==1)
{
      
if(array[j]>array[j+1])
{
swap(j,j+1);

}

}
else
{
  
if(array[j]<array[j+1])
{
swap(j,j+1);

}  
}
}

}  
  
}
swap(int j,int k)
{
int temp;
temp=array[j];
array[j]=array[j+1];
array[j+1]=temp;  
  
}
