Bubblesort -By C programming

Bubble sort, also known as sinking sort, is a simple sorting algorithm that works by repeatedly stepping through the list to be sorted, comparing each pair of adjacent items and swapping them if they are in the wrong order. The pass through the list is repeated until no swaps are needed, which indicates that the list is sorted. The algorithm gets its name from the way smaller elements "bubble" to the top of the list. Because it only uses comparisons to operate on elements, it is a comparision sort. Although the algorithm is simple, it is not efficient for sorting large lists; other algorithms are better.

Program:

# include<stdio.h>
# include<conio.h>
void bubblesort(int array[],int size);
void main()
{
int values[10],j;
for(j=0;j<10;j++)
values[j] = rand()%100;
/*unsorted*/
printf("\nUnsorted values.\n");
for(j=0;j<10;j++)
printf("%d ",values[j]);
/*sorted*/
printf("\nSorted values.\n");
bubblesort(values,10);
for(j=0;j<10;j++)
printf("%d ",values[j]);
}
void bubblesort(int array[],int size)
{
int tmp ,i,j;
for(i = 0;i
for(j=0;j < size;j++)
if(array[i] < array[j])
{
tmp = array[i];
array[i] = array[j];
array[j] = tmp;
}
}
