我从用户那里读取了 bMonth；
time_t timestamp = time(NULL);
tm* birthday = localtime(×tamp);
birthday->tm_mon = bMonth-1;
// now the tm_mon is set corectly
time_t birthStamp = mktime(birthday);
// now the tm_mon is 0
为什么 mktime 会改变值？
最佳答案
A call to this function automatically adjusts the values of the members of timeptr if they are off-range or -in the case of tm_wday and tm_yday- if they have values that do not match the date described by the other members.
关于C++ mktime 更改我的 tm_struct 的值，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19375113/
