The program takes in an words array (const char*) and outputs a char array with all the words padded to the length of the longest word. For example: ("None", "Critical", "Error", "Warning", "Debug", "Info", "All") gets padded to: [ None ][Critical][ Error ][Warning ][ Debug ][ Info ][ All ] (The square brackets are added to make it easier to see the spaces between different words.)
