 Write a C program to sort an array using Bubble sort technique.

2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

#include<stdio.h>   int main() {     int a[50],n,i,j,temp;     printf("Enter the size of array: ");     scanf("%d",&n);     printf("Enter the array elements: ");          for(i=0;i<n;++i)         scanf("%d",&a[i]);              for(i=1;i<n;++i)         for(j=0;j<(n-i);++j)             if(a[j]>a[j+1])             {                 temp=a[j];                 a[j]=a[j+1];                 a[j+1]=temp;             }                  printf("\nArray after sorting: ");     for(i=0;i<n;++i)         printf("%d ",a[i]);       return 0; }

Output

Enter the size of array: 4
Enter the array elements: 3 7 9 2

Array after sorting: 2 3 7 9
