1. ## Entry Level help.

I am trying to write a program that tells what time it is (am or pm) and what day of week it is when the user enters an hour number between 0 and 167 (7 days Monday at midnight starts at 0)

Heres what I have so far. I am working on the days of the week:

Code:
```     7  #include <stdio.h>
8
9  int main(void)
10
11  {
12
13  int hour;
14  #define day (Monday || Tuesday || Wednesday || Thursday || Friday || Saturday || Sunday)
15
16  printf("Enter hours: ");
17  scanf("&#37;d", &hour);
18
19  if (hour < 24)
20  day = Monday;
21  else if (hour > 23 || hour < 48)
22  day = Tuesday;
23  else if (hour > 47 || hour < 72)
24  day = Wednesday;
25  else if (hour > 71 || hour < 96)
26  day = Thursday;
27  else if (hour > 95 || hour < 120)
28  day = Friday;
29  else if (hour > 119 || hour < 144)
30  day = Saturday;
31  else ( hour > 143 || hour < 168)
32  day = Sunday;
33
34  printf("Result: %d\n", day);```

2. It looks like you're trying to do this in C, not C++.

You'd probably rather use an enumerative type for the day.
Check this out on enumerative types.

Since enumerative types have an integer value associated with them, a switch statement might be cleaner.
Check this out on using a switch statement.

3. Yes it is in C. I am having trouble what to use, a while loop? Cases? else if? Here are the directions.

Code:
```    10  DIRECTIONS: Write a C program which will prompt the user for
11  an int representing hours. This value will be in the range 0 - 167
12  inclusive. Your program should then display
13  a day and time (hours only) followed by am or pm.  Assume time begins
14  at midnight 12am Monday.
15
16  See the examples below:
17
18
19  EXAMPLES:
20
21  Enter hours: 0
22  Result: Monday, 12 midnight
23  PROGRAM ENDS
24
25  Enter hours: 12
26  Result: Monday, 12 noon
27  PROGRAM ENDS```

4. Can I do this

Code:
```#define Monday           0 < hour < 24
#define Tuesday        23 < hour < 48
#define Wednesday  47  < hour < 72
#define Thursday       71 < hour < 96
#define Friday            95 < hour < 120
#define Saturday      119 < hour < 144
#define Sunday         143 < hour < 168

int hour;```

5. Perhaps this should be moved to the C - board.

Anyways, are you familiar with pseudo-code (the steps your program will take to solve this problem without actually coding it)? That might be a helpful step.

Also, this program will greatly benefit from the use of functions.

6. I personally wouldn't use all the #define statements.

A simple solution might be to use the if-else if-else statement like you have to get the day, then use a function on the remaining integer value to calculate the hour of the day.

7. Ok sorry I thought I was in the C programming section. I must have had it bookmarked wrong. Thank you

8. just repost in the C section then.

9. Since this has been posted in the C programming forum...
