[C/C++] 날짜를 입력받고 timeStamp로 바꾸는 함수 !! ( date to TimeStamp in C/ C++)

안녕하세요, kimgaga 블로그 주인장입니다. 

이번 블로그글은 C/C++ 에서 timeStamp 를 날짜로 바꾸는 것은 

이전 포스팅에서 해봤습니다 !! http://kimgaga.tistory.com/453

이번에는 그 반대로인,

날짜를 입력받고 ( 년, 월, 일, 시간, 분, 초) 

그 시간을 컴퓨터가 알아보는 timeStamp값으로 바꾸는 코드를 보겠습니다 !! 

mktime 이라는 함수를 사용하면 되는데요 !! ( time.h 헤더 ) 

아래 코드에서 확인하세요 ~~

*******************

This writing is an example to transfer from date to timeStamp in C/C++

I write very easy so you can understand easily this code, but if you don't understand something, 

please comment in this posting or email to me. 

I use mktime funcfion which is in header "time.h", you can find this function in many other blog or wiki. 

If you want an example to transfer timeStamp to date, you can find an example in http://kimgaga.tistory.com/453 . 

Thank you for coming and have a nice day.
