C++ <ctime> - strftime() Function

The C++ <ctime> strftime() function converts the date and time information described in timeptr to a null-terminated multibyte character string str according to format string format, with a limit of maxsize characters.

Syntax

size_t strftime (char* str, 
                 size_t maxsize, 
                 const char* format,
                 const struct tm* timeptr );

Parameters

Return Value

Returns the total number of characters copied to str (not including the terminating null-character) on success. If maxsize is reached before the entire string could be stored, 0 is returned and the contents of the array pointed by str are undefined.

Example:

The example below shows the usage of strftime() function.

#include <iostream>
#include <ctime>

using namespace std;

int main () {
  time_t rawtime;
  struct tm * timeinfo;
  char buffer[80];

  time(&rawtime);
  timeinfo = localtime (&rawtime);

  strftime (buffer,80,"Current Date: %A, %F %I:%M %p", timeinfo);
  cout<<buffer;

  return 0;
}

The output of the above code will be similar to:
