Hi, I am very new to c programming, trying to learn by using, Stephen Kochan - Programming in C. I am having trouble getting a program (right out of the book, p. 183 to work. I have tried everything I know, but still cannot make 'er go. If someone could help, I would sure appreciate it.

struct time
{
int hour;
int minutes;
int seconds;
};

int main(void)
{
struct time timeUpDate(struct time now);
struct time testTimes[5] =
{ {11,59,59}, {12,0,0}, {1,29,59},
{23,59,59}, {19,12,27} };
int i;

for(i = 0; i < 5; i++) {
printf("Time is %.2i:%.2i:%.2i", testTimes[i].hour,
testTimes[i].minutes, testTimes[i].seconds);

testTimes[i] = timeUpdate(testTimes[i]);

printf("...one second later it's %.2i:%.2i:%.2i\n",
testTimes[i].hour, testTimes[i].minutes, testTimes[i].seconds);
}
return 0;
}

//funtion to update the time by one second
struct time timeUpDate(struct time now)
{
++now.seconds;
if(now.seconds == 60) { //next minute
now.seconds = 0;
++now.minutes;

if(now.minutes == 60) { //next hour
now.minutes = 0;
++now.hour;

if(now.hour == 24) //midnight
now.hour = 0;

}
}
return now;
}

Looks like you have a typo:

No anser to the question but please use code tags the next time when posting code. It will preserve the indentations and therefore makes it easier to read.
It will also make it easier if you highlight the line with error so we don't have to guess.

Good luck with the coding.

The error you was presented was not that helpful: C can be cryptic at times. I recommend compiling with the -Wall switch i.e.

Adding this in your case would have enabled you to spot the typographic error: you would have received a warning like:

Thus, pointing you to the real problem.

I have to admit my face is a little red right now, I went over that until I thought I would go blind. Thank you all for your responses, they have all helped me, later mortyg

Mortyg,

No reason to be embarrassed. I didn't spot the typo reviewing your post. I have been coding in C++ lately and after copying your code to my machine, out of habit I used g++ (that's my story and I'm sticking to it) and it spit out a much more informative error message:I think a quote from Douglas Adams "So Long, and Thanks for All the Fish" is apropos here: I know a lot of times I see what I'm expecting, especially when I am looking at my own code.
