bubble sort program using c language

#include<stdio.h>
#include<conio.h>

 void main()
{
int n,arr[100],i,j,temp=0;

clrscr();

 //here first  enter the size of the array

printf("enter the size of array");
scanf("%d",&n);

// enter the  data in array

     for(i=0;i<n;i++)
      {
      printf("\nenter the %d th data=",i+1);
      scanf("%d",&arr[i]);
      }
  //bubble sorting can  be implemented here

      for(i=0;i<n;i++)
      {
      for(j=0;j<n-i-1;j++)
      {
      if(arr[j]>arr[j+1])
      {
      temp=arr[j];
      arr[j]=arr[j+1];
      arr[j+1]=temp;
      }
      }
      }
      //  after sorting  display of the sorted list

     printf("\nafter sorting");
