C Code 14 _ To find unique elements in an array and find the third largest number in the array

Program:

#include<stdio.h>

int main()

{

    int n,i,j,t,a[30],b[30];

    printf("Enter the no of elements : ");

    scanf("%d",&n);

    printf("\nEnter %d elements : ",n);

    for(i=0;i<n;i++)

    {

           scanf("%d",&a[i]);        

    }

    for(i=0;i<n-1;i++)

    {

                      for(j=i;j<n;j++)

                      {

                                  if(a[j]>a[i])

                                  {

                                             t=a[j];

                                             a[j]=a[i];

                                             a[i]=t; 

                                  }   

                      }

    }

    printf("\nThe array in sorted order (descending) : ");

    for(i=0;i<n;i++)

    {

                    printf("%d ",a[i]);

    }

    printf("\nThe array in sorted order (ascending) : ");

    for(i=n-1;i>=0;i--)

    {

                       printf("%d ",a[i]);

    }

    b[0]=a[0];

    j=1;

    for(i=1;i<n;i++)

    }

    printf("\nUnique elements in array : ");

    for(i=0;i<j;i++)

    {

                    printf("%d ",b[i]);

    }

    printf("\nThe Third largest element is %d",b[2]);

    getch();
