Today we cover a variety of topics about strings, which mostly include String Operations in Modern C++ software. We will learn more string operations, mostly about wide strings (c++ std::wstring). We will explain converting string to wide strings, with examples. We will also hear about how the replace method can be used to replace part of a string with another string. We will learn to compare wide strings in modern C++. We will explain how to join and merge strings together. Also, we have a great IDE option example to speed up your compilation.
