Question

Problem 2: The Injury Severity Score (ISS) is a medical score to assess trauma severity and is calculated as follows. Each injury is assigned an Abbreviated Injury Scale (AIS) score in the range [0-5] which is allocated to one of six body regions (head, face, chest, abdomen, extremities, and external). Only the highest AIS score in each body region is used. The three most severely injured body regions (i.e. with the highest scores) have their AIS scores squared and added together to produce the ISS. Therefore, the value of the ISS is always between 0 and 75. Create a function called compute_iss that takes an array of 6 AIS values as its only input argument and produces the ISS value as its output. In your homework m-file, define the AIS array [3 0 4 5 3 0] and call to your function using this array as an argument. Find the ISS value for the defined AIS array. Make sure to add %comments.

Answer 1

1. #include <stdio.h>
2. int compute_iss(int ais[]);
3. int main()
4. {
5. int ais[6]=[3 0 4 5 3 0];
6. // ais array is passed to comput_iss()
7. iss = calculateSum(ais);
8. printf("ISS = %d", iss);
9. return 0;
10. }
11. int compute_iss(int ais[])
12. {
13. int a=0,b=0,c=0,i;
14. //a,b,c are for three highest numbers in an array
15. for (i = 0; i < 6; ++i)
16. {
17. // checks with the third largest number
18. if(ais[i]>a){
19. // checks with the second largest number
20. if(ais[i]>b){
21. // checks with the first largest number
22. if(ais[i]>c){
23.    /*if it is third largest number and third largest value is replaced with second largest
24. value and third largest value is replaced with second largest value and new value is
25. inserted into the first largest number*/
26. a=b;
27. b=c;
28. c=ais[i];  
29. }
30. else{
31. /*if it is second largest number and third largest value is replaced with second largest
32. value and new value is inserted into the second largest number*/
33. a=b;
34. b=ais[i];
35. }
36. }
37. else{
38.    //if it is third largest number and new value is inserted into the third largest number//
39. a=ais[i];
40. }
41. }
42. }
43.   // returns the iss value
44. return a*2+b*2+c*2;
45. }
