int a[20],i,j,n,c,flag;

printf("how many numbers u want to enter :\n");

scanf("%d",&n);

printf("\nenter the numbers :\n");

for(i=0;i<n;i++)

scanf("%d",&a[i]);

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

{

for(j=0;j<n-1-i;j++)

{

if(a[j]>a[j+1])

{

c=a[j];

a[j]=a[j+1];

a[j+1]=c;

flag=0;

}

}

if(flag)

break;

else

flag=1;

}

printf("sorted elements :\n");

for(i=0;i<n;i++)

printf("%d\t",a[i]);
