Solution:
- Bubble sort is used to sort 'n' numbers in ascending order.
- To sort these 'n' numbers start with 0th position element in array and compare it with a 1st position element. If 0th position element is found greater than 1stposition element, swap the elements. Similarly, compare all the elements in array.
#include<stdio.h>
#define maxsize 20
int main()
{
int array[maxsize];
int i, j, num, t;
printf("How many numbers you want to enter : ");
scanf("%d", &num);
printf("\nEnter %d numbers :\n",num);
for (i = 0; i < num; i++)
{
scanf("%d", &array[i]);
}
printf("\nInput array is : \n\n");
for (i = 0; i < num; i++)
{
printf("%d ", array[i]);
}
/* Bubble sorting begins */
for (i = 0; i < num; i++)
{
for (j = 0; j < (num - i - 1); j++)
{
if (array[j] > array[j + 1])
{
t = array[j];
array[j] = array[j + 1];
array[j + 1] = t;
}
}
} // end of sorting
printf("\n\nSorted array is : \n\n");
for (i = 0; i < num; i++)
{
printf("%d ", array[i]);
}
return 0;
}
Output:
