最后,使用strftime函数将tm结构体转换为日期时间字符串,并将结果存储在timestr数组中。最终,我们使用printf函数输出转换后的日期时间字符串。 总之,将时间戳转换为日期时间字符串是一项非常常见的任务,在C语言中可以使用time.h头文件中的函数来实现。通过使用time、gmtime和strftime函数,我们可以轻松地将时间戳转换为各种...
Converts the calendar time pointed to by timer to local time in the form of a character string. A value for timer is usually obtained by a call to the time() function. The ctime() function is equivalent to the function call: asctime(localtime(timer)) The function ctime64() will behav...
