Answer in code part

Code
  1. #include <stdio.h>

  2. #include <string.h>

  3. #include <conio.h>

  4. #include <stdlib.h>

  5. #define MIN_PER_HOUR        60.0F

  6. #define SEC_PER_MIN         60.0F

  7. #define SEC_PER_HOUR        (MIN_PER_HOUR*SEC_PER_MIN)

  8. #define DEGREE_FOR_1_HOUR   (360.0F/12.0F)

  9. #define DEGREE_FOR_1_SEC    (DEGREE_FOR_1_HOUR/SEC_PER_HOUR)

  10.  

  11.  

  12. int main()

  13. {

  14.         char time1[10] = {0};

  15.         char time2[10] = {0};

  16.         printf("%f

  17. ",DEGREE_FOR_1_HOUR);

  18.         printf("%f

  19. ",DEGREE_FOR_1_SEC);

  20.  

  21.         printf("Enter first time in hh:mm:ss format

  22. ");

  23.         fflush(stdout);

  24.         scanf("%s", time1);

  25.  

  26.         printf("Enter second time in hh:mm:ss format

  27. ");

  28.         fflush(stdout);

  29.         scanf("%s", time2);

  30.  

  31.         if(strcmp(time1, time2) > 0)

  32.         {

  33.                 const char delimit[2] = ":";

  34.                 int hour1, hour2, min1, min2, sec1, sec2;

  35.                 char *token;

  36.                 printf("time 1 = %s is greater

  37. ", time1);

  38.  

  39.                 token = strtok(time1,delimit);

  40.                 hour1 = strtol(token, (char **)NULL, 10);

  41.                 printf("%d

  42. ",hour1);

  43.                 token = strtok(NULL,delimit);

  44.                 min1 = strtol(token, (char **)NULL, 10);

  45.                 printf("%d

  46. ",min1);

  47.                 token = strtok(NULL,delimit);

  48.                 sec1 = strtol(token, (char **)NULL, 10);

  49.                 printf("%d

  50. ",sec1);

  51.  

  52.                 token = strtok(time2,delimit);

  53.                 hour2 = strtol(token, (char **)NULL, 10);

  54.                 printf("%d

  55. ",hour2);

  56.                 token = strtok(NULL,delimit);

  57.                 min2 = strtol(token, (char **)NULL, 10);

  58.                 printf("%d

  59. ",min2);

  60.                 token = strtok(NULL,delimit);

  61.                 sec2 = strtol(token, (char **)NULL, 10);

  62.                 printf("%d

  63. ",sec2);

  64.  

  65.                 float total_sec1 = (hour1)*SEC_PER_HOUR + (min1)*SEC_PER_MIN + (sec1);

  66.                 float total_sec2 = (hour2)*SEC_PER_HOUR + (min2)*SEC_PER_MIN + (sec2);

  67.  

  68.                 float angle = (total_sec1 - total_sec2) * DEGREE_FOR_1_SEC;

  69.                 printf("%f

  70. ", angle);

  71.         }

  72.         else

  73.         {

  74.                 printf("time 2 = %s is greater", time2);

  75.         }

  76.  

  77. }
