Program to find largest and smallest among 5 numbers without using array

Program to find largest and smallest among 5 numbers without using array

Yesterday I went for an interview where I have been asked to create a
program to find largest and smallest among 5 numbers without using array.
I know how to create the program using array.
int largestNumber;
int smallestNumber;
int numbers[n];
largestNumber=numbers[0];
smallestNumber=numbers[0];
for (i=0 ; i<n; i++)
{
if (numbers[i] > largestNumber)
{
largest = numbers[i];
}
if (numbers[i] < smallestNumber)
{
smallestNumber= numbers[i];
}
}
But how to create it without using array. Any help??
