C语言基础：延迟执行

#include <stdio.h>
#include <time.h>
int main (void)
 {
    time_t current_time;
    time_t start_time;
    printf("About to delay 5 seconds\n");
    time(&start_time);  // Get starting time in seconds
    do {
      time(&current_time);
    } while ((current_time - start_time) < 5);
    printf("Done\n");
	return 1;
