Good day Sir/Ma'am,

Just want to ask if you can help me with this one, and "Please sir/ma'am can you provide me a sample code" on how to do this in C language:


If an employee input a data like this:
--------------------------------------------------
Enter Time-in: 08:00
Enter Time-out: 17:01
Lunch Break: 1 hour

/* 9 hrs. in total deducted by 1 hour lunch break = 8 hours*/

Total No. of Working Hours:8 hours
--------------------------------------------------

How will i do this?

Thanks a lot....

Use scanf to get the times as separate hours and minutes. Then multiply hours by 60, add the minutes to it, do your math, and convert the time back into hours.

Sir thanks for your kind reply, but can you show me how... can you make a sample code on how to do that? thanks a lot sir...

This seems like homework. We'll gladly help, but we won't do it for you. Try it, and if it doesn't work then post your next question.

Sir i tried this one:

#include<time.h>

#include<stdio.h>

#include<conio.h>


main()

{

time_t start, end, total;


clrscr();

printf("Enter Time-in: ");

scanf("\n%s", &start);


printf("Enter Time-out: ");

scanf("\n%s", &end);


total = difftime(end,start);


printf("The total working hours is: %s ", total);


}

I get this WARNING: Function should return a value
and it doesn't give me the total

Please use code tags next time.

main() should always return a value, like this:

/* includes go here */

int main()

{

    /* put your code here */

    return 0;

}

Sir, i still get the same Warning.... Function should return a value and my code doesn't show the total of working hours? what is the problem of my code? thanks in advance

Okay, another problem: you can't use the %s specifier in printf or scanf for time_t. That's a long integer. You're going to have to do what I outlined above.
