int i,n,a[100];
printf("Enter a no:");
scanf("%d",&n);

printf("Enter %d no.s:",n);
for(i=0;i<n;i++)
scanf("%d", &a[i]);

biggest(a,n);

return 0;
}
void biggest(int a[],int n)
{
int big,i;
big=a[0];
for(i=1;i<n;i++)
{
if(big<a[i])
big=a[i];
}
printf("Biggest is %d\n",big);
}
void smallest(int a[],int n)
{
int small,i;
small=a[0];
for(i=1;i<n;i++)

{
if(small>a[i])
small=a[i];
}
