int maxmin(int num)
{
int min , max ,i,a[100], x , y;

int n=num;
printf(" Enter the elements in array : ");
for(i=0 ; i<n ; i++)
{
scanf("%d",&a[i]);
}
max = a[0];
min = a[0];

for(i=1; i<n; i++)
{
if(min > a[i])
min = a[i];

if(max < a[i])
max = a[i];
}

printf(" \n The maximum array is :%d",max);
printf("\n The minimum array is : %d",min);
}

int main()
{
int i , num, min, max,x, y;

printf(" Enter the size of the array : ");
scanf("%d",&num);

x = maxmin(num);

return 0 ;
}
