C Program to Sort Array in Ascending Order

In this tutorial, i am going to show you how to sort array in ascending order with the help of standard method, function, and pointer in c programs.

C Program to Sort Array in Ascending Order using Standard Method

#include <stdio.h>
 
int main()
{
    int a[10000],i,n,j,temp;
   
    printf("Enter size of the  array : ");
    scanf("%d", &n);
    printf("Enter elements in array : ");
    for(i=0; i<n; i++)
    {
        scanf("%d",&a[i]);
    }
      
     
    for(i=0; i<n-1; i++)
    {
           
        for(j=0; j<n-i-1; j++)
        {
           if(a[j]>a[j+1])
           {
           	temp=a[j];
           	a[j]=a[j+1];
           	a[j+1]=temp;
		   }
 
        }
       
    }
    printf("\narray elements in ascending order:\n ");
 
    for(i=0; i<n; i++)
    {
       printf("%d ",a[i]);
    }
    
 }

The result of the above c program; as follows:

Enter size of the  array : 5
Enter elements in array : 1 8 7 2 6
array elements in ascending order:
 1 2 6 7 8 

C Program to Sort Array in Ascending Order using Function

#include <stdio.h>
 
int sort(int *a,int n)
{ 
    int i,j,temp;
     for(i=0; i<n-1; i++)
    {
           
        for(j=0; j<n-i-1; j++)
        {
           if(a[j]>a[j+1])
           {
           	temp=a[j];
           	a[j]=a[j+1];
           	a[j+1]=temp;
		   }
 
        }
       
    }
    
    
       
 }
 print(int *a,int n)
{ 
   
    int i;
    for(i=0; i<n; i++)
    {
       printf("%d ",a[i]);
    }
    
       
 }
 
  
int main()
{
    int a[10000],i,n,key;
   
    printf("Enter size of the  array : ");
    scanf("%d", &n);
    printf("Enter elements in array : ");
    for(i=0; i<n; i++)
    {
        scanf("%d",&a[i]);
    }
     
   sort(a,n);
      print(a,n);
 
     
    
}

The result of the above c program; as follows:

Enter size of the  array : 5
Enter elements in array : 5 4 3 2 1
1 2 3 4 5 

C Program to Sort Array in Ascending Order using Pointer

#include <stdio.h>
void SortArray(int Size, int* parr)
{
	int i, j, temp;	
	for (i = 0; i < Size; i++)
	{
		for (j = i + 1; j < Size; j++)
		{
			if(*(parr + j) < *(parr + i))
			{
				temp = *(parr + i);
				*(parr + i) = *(parr + j);
				*(parr + j) = temp;
			}			
		}
	}
	printf("\nSorted Array Elements using Pointer = ");
	for(i = 0; i < Size; i++)
	{
		printf("%d  ", *(parr + i));
	}	
}
int main()
{
	int Size;
	printf("\nEnter Array Size to Sort using Pointers = ");
	scanf("%d", &Size);
	int arr[Size];
	printf("\nPlease Enter %d elements of an Array = ", Size);
	for (int i = 0; i < Size; i++)
	{
		scanf("%d", &arr[i]);
    }  	
	SortArray(Size, arr);   
	printf("\n");	
}

The result of the above c program; as follows:

Enter Array Size to Sort using Pointers = 5
Please Enter 5 elements of an Array =  4 3 2 1 0
4 3 2 1 0

Sorted Array Elements using Pointer = 0  1  2  3  4
