Jan 31, 2020 · std::string has two modes: long string and short string. It uses a union to reuse the same bytes for both modes. Short string mode is an optimization which makes it possible to store up to 22 characters without heap allocation. Long string mode. The long string mode is a pretty standard string implementation. There are three members:

Feb 1, 2022 · In this article, we will create our custom string class which will have the same functionality as the existing string class. Constructor with no arguments: This allocates the storage for the string object in the heap and assign the value as a NULL character.

Apr 6, 2020 · Below is the complete implementation of the my_string class. I have overridden the ostream operator to support outputting our string to console using std::cout.

Here are Standard, simple, and portable ways to perform common transformations on a string instance, such as "convert to all upper case."
