Exit a loop at anytime
Sorry but I have another problem. If I change 'time_t end = time(0) + 1;' to 'time_t end = time(0) + 5;'... Then my program will not exit the loop straight away but exits after 5 seconds. How can I change it to exit the loop straight away? Let's say if it were to be a minute, cause I'm creating a program, a parking meter where you can exit the loop anytime to claim for refunds. Reference to the code below :
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(void)
{
int b=0, i;
int seconds;
printf("\nEnter number of seconds : ");
scanf("%d", &seconds);
while (b==0)
{
b=kbhit();
for(i=1;i<=seconds;i++)
{
while (b==0)
{
b=kbhit();
time_t end = time(0) + 5; //5 seconds delay.
while(time(0) < end)
{
b=kbhit();
}
seconds -= 5;
printf("Number of seconds left : %d\n", seconds);
b=kbhit();
}
}
if(seconds == 0)
{
exit(0);
}
b=kbhit();
}
printf("Number of remaining seconds left : %d\n", seconds);
}
