PROGRAM TO SORT THE NUMBERS USING BUBBLE SORT

Here is the program to sort the given integer in ascending order using bubble sort method. Please find the link to the pictorial tutor of the sorting. This program needs to enter the length of the entering array, followed by the array to be sorted

Logic :  The entered integers are stored in the array A. Here, to sort the data in ascending order, any number is compared with the next numbers for orderliness. i.e. first element A[0] is compared with the second  element A[1]. If forth is greater than the prior element then swapping them, else no change. Then second element is compared with third element, and procedure is continued. Hence, after the first iteration of the outer for  loop, largest element is placed at the end of the array. In the second iteration, the comparisons are made till the last but one position and now second largest element is placed at the last but one position. The procedure is traced till the array length.

If we complement the if condition in this program, it will give out the sorted array in descending order. Sorting can also be done in other methods, like selection sorting and insertion sorting, which follows in the next pages.

#include<stdio.h>
void main()
{
     int A[20], N, Temp, i, j;
     clrscr();
     printf("\n\n\t ENTER THE NUMBER OF TERMS...: ");
     scanf("%d",&N);
     printf("\n\t ENTER THE ELEMENTS OF THE ARRAY...:");
     for(i=1; i<=N; i++)
     {
           gotoxy(25, 11+i);
           scanf("\n\t\t%d", &A[i]);
     }
     for(i=1; i<=N-1; i++)
          for(j=1; j<=N-i;j++)
               if(A[j]>A[j+1])
               {
                     Temp = A[j];
                     A[j] = A[j+1];
                     A[j+1] = Temp;
                }
     printf("\n\tTHE ASCENDING ORDER LIST IS...:\n");
     for(i=1; i<=N; i++)
     printf("\n\t\t\t%d",A[i]);
     getch();
}
