Bubble Sort Algorithm in C language

Bubble sort
Its an easy sorting algorithm to learn and implement.Bubble sort algorithm is good for Small data set . It is not good for larger data sets.

code...

#include<stdio.h>
int main(){
    int a[5]={2,1,0,4,7},i=0,j=0,n=5,temp=0;
    for(i=0;i<n;i++){
        for(j=0;j<n;j++){
// Comparing the elements
            if(a[j] > a[j+1]){
                temp = a[j];
                a[j] = a[j+1];
                a[j+1] = temp;
            }
        }
    }
// Print the Sorted Array
    for(i=0;i<n;i++){
        printf("%d\t",a[i] );
    }
    return 0;
}

I have taken an array and we are comparing last previous element with the next element and if previous element is larger than current element than Swap them.

if(a[j] > a[j+1]){
                temp = a[j];
                a[j] = a[j+1];
                a[j+1] = temp;
 }
This part is main part which is swapping the elements with current and previous elements.
