DATETIME like YYYYMMDDHHMMSS

[Jazzhouse]

Hi,

How do you get the local date time as YYYYMMDDHHMMSS 14 digit string???

I am very new to C++, but if the MSDN tutorials are like that may be it
is better to go with GCC... :)

You can do it the same way in C, C++, VC++, gcc, g++, in fact in any C or
C++ compiler in the world.

#include <time.h>
#include <stdio.h>

time_t t = time(0);
struct tm* lt = localtime(&t);
char time_str[15];
sprintf(time_st r, "%04d%02d%02d%0 2d%02d%02d",
lt->tm_year + 1900, lt->tm_mon + 1, lt->tm_mday,
lt->tm_hour, lt->tm_min, lt->tm_sec);

Untested code

Which part of the above is C++?

All of it apparently.

Starting with two deprecated headers and followed by pure C code. Here and
there introducing the opportunity for buffer overruns. I see. It is code
which compiles with a C++ compiler. I would not call it C++ code.

Oh, Atilla, you are SO fussy!

All of it. Remember that the C++ standard library contains
the (C90) C standard library. Also, tHe headers with .h, while
deprecated, are indeed part of standard C++.

which also qualifies as 'pure C++ code'.

That's a quality issue.

Call it what you like. It *is* C++, according to 14882.

Try:
#include <iostream>
#include <iomanip>
#include <ctime>

int main()
{
time_t t = time(0);
struct tm *lt = localtime(&t);
std::cout << std::setfill('0 ');
std::cout << std::setw(4) << lt->tm_year + 1900
<< std::setw(2) << lt->tm_mon + 1
<< std::setw(2) << lt->tm_mday
<< std::setw(2) << lt->tm_hour
<< std::setw(2) << lt->tm_min
<< std::setw(2) << lt->tm_sec
<< std::endl;

int Blah()

}

int main()

Blah(8);
}
Case and point.

C is irrelevant here.
