Here is the program to set the array elements in the ascending order
Code:
#include <stdio.h>

int main()

{
     int Arr[100],n,i,step,temp;

     printf("Enter the number of array elements\n");

     scanf("%d",&n);

     for(i=0;i<n;++i){

        printf("Enter Arr%d:\n",i+1);
        scanf("%d",&Arr[i]);
     }

     for(step=0;step<n-1;++step)
        for(i=0;i<n-step;++i)
        {
           if(Arr[i]>Arr[i+1])    
           {
              temp=Arr[i];
              Arr[i]=Arr[i+1];
              Arr[i+1]=temp;
           }
        }
     printf("In ascending order:\n");
     for(i=0;i<n;++i)
         printf("%d\t",Arr[i]);
     return  0;
}
