Let see…

To find the minimum number in an array you will have to browse through an array filled with random numbers and compare each find with a the previously lowest find until the end if reached.

Example:

Array filled with random numbers: 9 3 2 4 6 1 7 8 10

Minimum Number is: 1

In the example above we grab as initial vale “9” and compare it with the rest of the elements in the array. Is “3” lower than “9” –  YES! Then, the minimum number becomes “3” subsequently until the loop finds the minimum number “1” and reaches the end of the array.
