C++中头文件<ctime>包含哪些函数

C Time LibraryThis header file contains definitions of functions to get and manipulate date and time information.

FunctionsTime manipulation clockClock program (function)difftimeReturn difference between two times (function)mktimeConvert tm structure to time_t (function)timeGet current time (function)

Conversion:

asctimeConvert tm structure to string (function)ctimeConvert time_t value to string (function)gmtimeConvert time_t to tm as UTC time (function)localtimeConvert time_t to tm as local time (function)strftimeFormat time to string (function)

Macros CLOCKS_PER_SECClock ticks per second (macro)NULLNull pointer (macro)

types clock_tClock type (type )size_tUnsigned integral type (type)time_tTime type (type)struct tmTime structure (type) 请参阅：http://www.cplusplus.com/reference/clibrary/ctime/

不需要重装。conio.h 是个很小的头文件。根据你的编译器类型和版本，下载一个，或找谁复制一个。

例如 MS C V2.03 compatible console I/O 如巧中下枣渗：

/***
