Write a bubble sort using c program.

Output:
Enter total numbers of elements: 5
Enter 5 elements: 6 2 0 11 9 After sorting: 0 2 6 9 11

Code:
#include<stdio.h>
int main(){


int s,temp,i,j,a[20];


printf("Enter total numbers of elements: ");
scanf("%d",&s);


printf("Enter %d elements: ",s);
for(i=0;i<s;i++)
scanf("%d",&a[i]);



for(i=s-2;i>=0;i--){
for(j=0;j<=i;j++){
if(a[j]>a[j+1]){
temp=a[j];
a[j]=a[j+1];
a[j+1]=temp;
}
}
}


printf("After sorting: ");
for(i=0;i<s;i++)
printf(" %d",a[i]);


return 0; }
