Importing data from a text file and then working on it ,
definitely a nice work and code has been nicely written too
....
But what you missed was the few typing errors , and to sort out
that , Indenting the code is the best approach
1. At line no. 20 :-> In the for loop it was used "day" while "days" was initialized because whatever indexing variable one is using the array only that variabe should be used . Also it was written "day=30;day,31;day++" but it should be "days=0;days<31;days++".
2. At line 28 :-> A semicolon was missed . "sum = 0" typo error as "sum = 0;" was required
3. At line 40. :-> Same mistake of typo error . "average = sum/num:"
4. At one place the closing bracket was placed 3 lines earlier
resulting in "printf("Month %d: %f percent of days in range.",
average, month);" printing only once , while it was intended to
print in the loop
Hence, At line 39 :-> The closing braacket was placed "}" while
this bracket should have come after line 42.
Code For refrencing line numbers : (I have indented the code as
it always helps me out)
1. #include <stdio.h>
2. #include <stdlib.h>
3. #define MONTHS 12
4. #define DAYS 31
// Main Function
5. int main(void){
6. FILE* f;
// Declared Variables
7. int month, day, low, high, sailmonth[12], temperature, besttime,
i, j;
8. float array[MONTHS][DAYS],num, sum, average;
9. char data[30];
10. printf("Please enter the name of the weather data
file:/n");
11. scanf("%s", data);
12. printf("Tell me about your crew’s preferred temperature for
sailing:/n");
13. printf("What is the coldest temperature they can sail
in?/n");
14. scanf("%d", &low);
15. printf("What is the hottest temperature they can sail
in?/n");
16. scanf("%d", &high);
17. if((f = fopen(data, "r")) == NULL)
18. exit(1);
19. for(months = 0; months < 12; months++){
20. for (day = 0; day ,31; day++){ ******************
21. if(fscanf(f, "%f", &array[months][days]) != 1)
********************
22. exit(1);
23. fclose(f);
24. }
25. }
26. for (months = 0; months < 12; months++)
27. {
28. sum = 0 *******************
29. num = array[months][0];
30. for (days = 1; days <31; days++)
31. {
32. if (array[months][days] >= low &&
array[months][days] <= high)
33.
34. {
35. printf("%f", array[months][months]);
36. sum = sum + array[months][months];
37. }
38. }
39. } ****************
40. average = sum/num: ***************
41. printf("Month %d: %f percent of days in range.", average,
month);
42. sailmonth[month] = int (average);
****************
43. for (i = 0; i < 12; i++)
44. {
45. besttime = 0;
46. for (j = i + 1; j < 12; j++)
47. {
48. if (sailmonth[i] > sailmonth[j])
49. {
50. temperature = sailmonth[i];
51. sailmonth[i] = sailmonth[j];
52. sailmonth[j] = temperature;
53. besttime = i;
54. }
55. }
56. }
57. printf("You should leave for the Carribean in month %d.",
besttime);
58. return 0;
59. }
