// Purpose: Determine which of 2 patients should be seen

// next by a doctor by computing injury severity

// score (which is based on region of body affected,

// subregion of body affected, and type of injury,

// all of which are user inputs)

//

// To compile: fg++ hw3.cpp -o hw3

//

// To execute: ./hw3
