Table 9.28 shows the modifier patterns for date/time formatting.įM suppresses leading zeroes and trailing blanks that would otherwise be added to make the output of a pattern be fixed-width. For example, FMMonth is the Month pattern with the FM modifier. Modifiers can be applied to any template pattern to alter its behavior. Time-zone offset from UTC (only supported in to_char) Lower case time-zone abbreviation (only supported in to_char) Upper case time-zone abbreviation (only supported in to_char) Month in lower case Roman numerals (i–xii i=January) Month in upper case Roman numerals (I–XII I=January) Julian Date (integer days since NovemBC at local midnight see Section B.7)

We learned about three different ways to convert a string into char* in C++. It converted a string to a char pointer in C++. Std::copy(sampleText.begin(), sampleText.end(), textArr)
Std::string does the contiguous memory allocation for characters. C++11 onwards, then you can directly take the address of first character of string i.e.
If you are using the latest compiler of C++ i.e. Std::string sampleText = "This is a sample text" Ĭhar* textPtr = const_cast(sampleText.data()) So, we can use this to get a const char to the characters in the string. It returns a const pointer, pointing to the internal contents os string. In C++, the string class provides a member function data().
