The whole event takes place on mars, so you can see the different time intervals for minutes, hours and days respectevely at the top.

I'm supposed to create a menu for the user, (set time/start timer/quit)

as you can see, most of that is already input.

next i am to take the current time and print in seconds until the interval provided expires. (for example using EARTH, if its 2:00:00 and he wants me to count for an hour i'm supposed to print every second until three a clock.)

i hope that makes sense

i don't know how to continue from here

please advise

Michael

PS theres more to it, i'm just trying to understand it step by step

Looks like you need a loop. You'll need to think about how a clock works, and duplicate that process. Surely you've got some idea how a clock works. Let's see you give it a shot.


Quzah.

convert total time in interval to seconds

add seconds to original time incrimenting minutes and hours when necessary but how?

i'm not asking for a complete solution, just something to point me in a better direction compared to what i have now.

What happens on a clock when it reaches 59 seconds and needs to increment? Quite obvious, really.

i understand the logic behind what is asked of me, the only problem is the mental leap of being able to explain it to the computer.

this is my first year in C so i'm still learning

Since you're using #defines

Code:

---

#define HRS_DAY 20 //define hours per day
#define MINS_HR 12 //define minutes per hour
#define SECS_MIN 15 //define seconds per minute

---

why not change them to "Earth" for development and initial debugging, and then later change them back?

i like where your heads at

Code:

---

total = (hT * MINS_HR * SECS_MIN) + (mT * SECS_MIN) + (sT);
printf("HERE WE GO!\n");
while (total > 0){
        printf("%d:%d:%d", h, m, s);
        if (s == SECS_MIN)        {
                        m = m +1;
                        s = 0;
                        }
        if (m == MINS_HR)        {
                        h = h + 1;
                        m = 0;
                        }
        if (h == HRS_DAY)        {
                        h =0;
                        }
        total = total - 1;
        }

You will keep on printing same values of h,m,s.
You have to increment s in while loop.otherwise your If statements will not work the way you want it.

i appreciate your reply, everything seems to be working now except rolling over to the next day..which i will fix

Gotta increment your seconds in that, Tonto. Also, don't forget, that code's "second" is the time it takes to loop. In otherwords, rediculously fast. You'll need to use a sleep function if you want proper speed.

Code:

---

printf("%d:%d:%d\n", h, m, s);
s++;
if (s == 60)        {

---

Code:

---

else if (menu_choice == 2)        { //begin menu choice 2
                        printf("How long would you like me to count?\n");
                        scanf("%d:%d:%d", &hT, &mT, &sT);
                        total = (hT * MINS_HR * SECS_MIN) + (mT * SECS_MIN) + (sT);
                        Bt = total - breakfast;
                        Lt = total - lunch;
                        Dt = total - dinner;                       
                        printf("HERE WE GO!\n");
                                while (total > 0)        {
                                        printf("%d:%d:%d", h, m, s);
                                        s = s + 1;
                                                if (s == SECS_MIN)        {
                                                        m = m +1;
                                                        s = 0;
                                                }
                                                if (m == MINS_HR)        {
                                                        h = h + 1;
                                                        m = 0;
                                                }
                                                if (h == HRS_DAY)        {
                                                        h = 0;
                                                }
                                        total = total - 1;
                                        printf("\n");
                                }
                } //end menu choice 2

User inputs start time and amount of time wanted to count for. I'm required to remind the user to eat breakfast between 4:00:00 and 5:00:00

i already have a random number for the amount of seconds in the breakfast break interval, Bt.

now i just need to remind the user after the specified seconds...please help me

Code:

---

while (total > 0) {
        printf("%d:%d:%d", h, m, s);
        s = s + 1;
        if (s == SECS_MIN) {
                m = m + 1;
                s = 0;
                }
        if (m == MINS_HR) {
                h = h + 1;
                m = 0;
                }
        if (h == HRS_DAY)
                h = 0;
        total = total - 1;
        if (total == Bt)
                printf("\nIt's breakfast time!");
        printf("\n");
}

---

sadly nothing

Well I can only assume with the variable breakfast contains. So I can't write you exact statement. By the way, when people write this code, it's not for you to copy and paste, it's for you to learn from.

my fault i mis-understood your intentions, i will continue working at it and i appreciate your help.

Code:

---

#include <stdio.h>

#define MINS_HR 60 //define minutes per hour
#define SECS_MIN 60 //define seconds per minute

int main(void)        {

        int total;
        int h, m, s;

        printf("How many seconds whould you like to convert?\n");
        scanf("%d", &total);
       
        h = (total / (MINS_HR * SECS_MIN));
        if (h >= 1)        {
                total = total - (MINS_HR * SECS_MIN);
                if (h <= 0)        {
                        h = 0;
                }
        }
       
        m = (total / SECS_MIN);
        if (m >= 1)        {
                total = (total - (SECS_MIN * m));
                        if (m <= 0)        {
                                m = 0;
                        }
        }

        s = total;
        printf("%d:%d:%d", h, m, s);
}

this program is supposed to convert seconds to hours:minutes:seconds...for example, 4000 seconds would be 01:06:40.

is this the most efficient way? i've noticed that it doesn't work for all inputs. higher amount of seconds, the less accurate the output is. please advise.

This is a lot easier if you also use the % modulo operator.
h = total / 3600;
ms = total % 3600;
m = ms / 60;
s = ms % 60;

Code:

---

                total = total - (MINS_HR * SECS_MIN);

---

shouldn't this be:

Code:

---

                total = total - (MINS_HR * SECS_MIN * h);

haha, oh man you don't know how much i appreciate you guys

thanks so much,
