Timed functions
I am reading the How to program in C book by Deitel, and at the end of chapter 7, we are supposed to make a program (the source code is not given) that simulates a race between a rabbit and a turtle.
It says that the animals are going to move through the race, every second. This means that I am goint to have either a function that is executed every second. I know I will have to use time.h, but how do I go about doing this?
Thanks.
Code:#include <time.h> #include stuff function prototype int main() { while(1) { function(); wait(1); } return 0; } void wait( int seconds ) { clock_t endtime = clock() + seconds * CLOCKS_PER_SEC; while ( ( clock() < endtime ) ); }
The world is waiting. I must leave you now.
or if you have dos.h, you can use delay(1000) instead of void wait().
example:
Code:int main() { while( /* argument(s) */ ) { // code... delay(1000); } return 0; }
Since you're only supposed to simulate time, there's no need to complicate it by synchronising this to real time (unless you want to).
Code:for ( seconds = 0 ; seconds < 20 ; seconds++ ) { // calculate distance, based on velocity and elapsed time // for the rabbit and turtle }
