// Problem: A user is asked to enter 10 positive numbers. 
// We will then go through these numbers and find the 
// lowest number and output what the lowest number is 
// to the user.

// 1) Scanf in while loop to take in 10 numbers
// 2) Store in an array 
// 3) Find the lowest of the numbers
// 4) Output the lowest number to terminal
