Bubble Sort Using Function

#include <stdio.h>
int a[100],l,i,j,temp;

  for (i = 0; i <(l-1); i++)

    printf("The sorted array is:-\n");
    for(i=0;i<l;i++)

int main()

}
//Output
//Enter the array's limit.5
//Now enter 5 elements to fill the array.
//9
//-1
//1
//0
//67
//The sorted array is:-
//-1      0       1       9       67
